What you need to know about DAN SENTRY

Data Acquisition Networks provides a range of data loggers and data logging solutions applicable to temperature monitoring, environmental monitoring, process monitoring and a vast array of other commercial applications.

1. General Information

DAN SENTRY is an online data storage system. It is available to customers who have purchased and installed DAN field hardware on site and where that hardware sends data to and receives data from the DAN SENTRY web site.

2. What does DAN SENTRY Allow You to DO

You can do the following using DAN SENTRY:

• Set up your data base
• Access data held in your data base
• Set up alarm functions and parameters for your field hardware
• Calibrate your system
• Place field hardware into ‘GROUPS’
• Add or remove users and change passwords

DAN SENTRY provides you with a high level of control over the entitlements of your staff to access data or change site operational factors.

3. Security

Every person accessing data, changing set-up conditions or carrying out an administrative role, must have been issued with a Security Identification by you or by an authorised administrator appointed by you. Access will only be granted to issued Security Identifications and to the extent of entitlements assigned to those Security Identifications.

4. Ability to control entitlements

You are in control of and can issue each user with a Security Identification and set the entitlements of each user to access. DAN SENTRY functions. This includes the ability to view data, change site operational factors and to manage administrator functions. All changes made to the system are tracked and logged and form part of the data stored.

5. What are the charges?

The current fees for DAN SENTRY will be agreed with DAN and set out in the DAN SENTRY Fee Schedule.

6. What are the risks?

All Web based products involve a certain amount of risk. For DAN SENTRY, we strongly recommend that you implement robust information systems management processes appropriate to your PC or network. We also strongly recommend that you implement and regularly review the risks associated with your own internal procedures and controls.

7. Data integrity.

You are responsible for ensuring that your site operational factors including alarm conditions and calibrations are complete and accurate. Incorrect or incomplete information will result in no or potentially worthless data and alarm alerts.

8. Unauthorised access

Adequate security precautions must be taken to prevent an unauthorised user accessing your data and/or changing your site operational factors. This should include the use of appropriate anti-’spamming’, anti-’key logging’ and anti-‘Virus’ software in addition to appropriate personal computer or network ‘firewall’ protection.

9. Operational risk

Operational risk is the risk of loss resulting from failed internal processes, people and systems or actions because of external events. You rely on the ability of DAN to provide your data and process your changes to site operational factors in a timely and accurate manner. DAN in turn is   dependent on the reliability of its own operational processes that include public communication networks, computers and associated infrastructure. Whilst we take great care to

ensure that our systems and processes are robust, disruptions to DAN’s processes may lead to delays in the retrieval of your data or alarms or the processing of changes to site operational factors. DAN is not liable to you for any direct or consequential losses which arise from disruptions to our systems or processes.

The above is a general summary of DAN SENTRY. You should read the TERMS & CONDITIONS before deciding whether DAN SENTRY is the service for you.

CASE STUDY - POOD PROCESSING

Food manufacturers are required to monitor and record Critical Control Point (CCP) information as a part of a compliant HACCP (Hazard Analysis and Critical Control Point) system. Record-keeping is critical to a food safety auditor’s determination of compliance.

Depending upon the type of food being processed the critical control points will change. The safety of some products is temperature dependent whereas for others sanitizing is critical to ensure bacteria counts are at the required level prior to the product being frozen or chilled for transport and sale. In the poultry processing industry for example, both temperature and sanitization are critical to effective production.

Current practices of determining the operating quality of sanitized water in the poultry processing industry requires the periodic measurement of free chlorine and pH.  From an operational standpoint, automated measurement of pH is practical and already in place in many applications Much thought must be given to the sampling method as pH probes can notoriously become saturated with fats and greases and perform sub-optimally as a consequence. Automated measurement of free chlorine however requires expensive apparatus and fats or oils once again need to be considered for their impact on probe efficiency. This has traditionally made automated monitoring solutions problematic and expensive!

Current practical methods of data collection involve manual immersion of sensitive strips followed by colour matching to standards or involve the use of hand-held probes. These methods cannot provide alerts when water parameters are changing nor can a manufacturer be certain the readings are being consistently taken from the same point. The method is also limited by the ability to match colours by eye and relies upon people not forgetting to sample. The method often results in over-dosing of chlorine because of its inherent imprecision.

An alternative method of determining the sanitizing quality of the water is to utilise the measurement of ORP (Oxidation Reduction Potential) along with the measurement of pH.  ORP is a direct measure of the effectiveness of the free chlorine in the water and varies with changes in chlorine levels and also with changes in pH.  Harvard University has concluded and published the recommendation that ORP levels for poultry sanitization be above 625mV.  As measurement of both pH and ORP can be mechanized, a continual monitoring process has been developed by DAN that can be implemented with alarms generated by changes being sent in real time. The financial benefits are in reduction in chlorine usage (and cost) reduction in sampling labour cost and improved sanitizing leading to the option for shelf-life extension. The food safety benefits come from greater control over a critical process.

As can be seen from the sample data below, DAN presents an AVERAGE, a MAXIMUM and a MINIMUM for each reporting period, for each critical control point. DAN systems automatically generate the information necessary to fulfill the requirements of HACCP record-keeping.

The system provides data available for viewing on a web site accessible from any computer via the internet (Passwords and login ID’s protect the data).  In addition, alarms may be generated by email and SMS to preset conditions also input via the internet.

DAN has also developed an Operator’s Console view that can be used within a factory by Supervisors, Quality Controllers and Operators to constantly monitor the process at a glance.

The above graphic is representative of the DAN Console view.

SCIENTIFIC EVIDENCE

There is a significant body of scientific evidence constructed by large ‘learning’ organisations that support the use of ORP measurement and the correlation between ORP levels and the survival rates of micro organisms. The table below provides a useful summary.

 Before DAN developed the ORP monitoring system for poultry processing, automated monitoring was cumbersome, expensive and unreliable. Similarly, manual monitoring and record-keeping was a less than ideal solution.

DAN currently sells and installs food processing equipment at a fraction of the cost of alternatives and is proud of what it has achieved whilst working hand-in-hand with major manufacturers.

What is TRUE data monitoring?

True data monitoring is in place when there is a system that is automated (i.e. it is not dependent on human action) and which collects data routinely and stores that data so it cannot be tampered with and it cannot be lost. True data monitoring also does not allow humans to interpret what they believe the data should be!

Data Acquisition Networks provides true data monitoring. Inputs are polled each second and the data averaged and a maximum and a minimum for the ‘reporting period’ transferred automatically to a website where it is stored for access by those with password authorisation. The data is accessed in much the same way as you retrieve your banking details.

Data Acquisition Networks provides true data monitoring solutions for minimal cost.

Food Standards Australia requires businesses to prepare and sell food that is safe to eat. Food causes illness because there are high levels of food-poisoning bacteria and these poisons are called toxins. “A way of preventing or limiting bacteria from multiplying or producing toxins in food is to control the temperature of the food by either keeping it cold or very hot”. Food Standards Australia requires potentially hazardous foods to be kept at 5degC or colder and prescribes that it is “safe for food to be between 5degC and 60degC for a limited time only”. Health regulators and inspectors commonly refer to the range between 5degC and 60degC as the DANGER ZONEfor perishable foods. Food Standards Australia defines potentially hazardous foods as foods that might contain food-poisoning bacteria and which will allow food-poisoning bacteria to multiply. Examples of potentially hazardous foods are listed as raw and cooked meat, smallgoods, dairy products, seafood, processed fruit and vegetables, cooked rice and pasta, foods containing eggs, beans and nuts and foods that contain these foods for example sandwiches and rolls. Many of these food types are also the foods that are inclusions in a balanced and nutritious diet.  Food Standards Australia also requires that potentially hazardous frozen foods are kept frozen when they are stored, displayed or transported. Whilst no specific temperature is specified for frozen food it must be kept frozen to remain safe. Temperature abuse of frozen food can also have a detrimental impact on eating quality. It is commonly accepted that -18degC is a safe temperature at which frozen food should be stored. It is also generally agreed that infrequent but consistent temperature abuse can have a detrimental impact on the shelf-life of food and with some foods temperature abuse can also affect its nutrient value. Food Standards Australia prescribes food that has been temperature abused for a continuous period of greater than 4-hours should be discarded. The NSW Food Authority recommends perishable foods should not be left in the danger zone for longer than 2-hours!
