Wireless transmitters & receivers
Data Acquisition Networks has developed wireless transmitters and receivers for local data transfer. Not just hardware, but intelligent combinations able to produce various outputs including via a RS232 port in a human readable format. For probes that are located at distance from the gathering point or are located where wiring is too difficult, the DAN wireless system may provide the ideal answer. Designed to link with the DAN data logging product, with an on site system or with both simultaneously, DAN wireless technology has advanced the transmission of data from where it is gathered to where it is needed to new heights. And as is typical with DAN products, simplicity of operation is the key.
Estuarine monitoring using wireless loggers
Data Acquisition Networks has a history of successful involvement with the monitoring of estuarine water quality through maintaining salinity records that are an indicator of water water impurity. Put simply, when it rains and there is run-off from land into the estuary there is a probability the water will become impure. By correlating water salinity with meat quality the aquaculture industry is able to determine at what salinity level an estuary should be closed for aquaculture harvesting.
New wireless transmitters from DAN enable multiple points within an estuary to be monitored from one data logger positioned in a farmer’s shed. This enables readings to take into account tidal flows that may conclude rainfall does not effect every point in an estuary equally.
Data loggers from DAN continue to lead the way in estuarine salinity monitoring.
Transmitters for local data transmission
During July 2008 Data Acquisition Networks has announced the release of NEW WIRELESS TRANSMITTERS & RECEIVERS for ‘local’ data transmission.
Wirreless transmitters and receivers save substantial time and money. They are flexibly locatable on a site and require NO ‘HARD’ WIRING!
One DAN receiver can accommodate multiple DAN transmitters and can transmit data over a distance of 2 kilometers. Each transmitter can take up to 6 inputs and the receiver can transfer data to you SCADA system or can be connected to a DAN DM01 data logger from where data can be transferred to your desk wherever that may be located.
Wireless transmitters and receivers
DAN Wireless Transmitters and Receivers are designed for a wide range of applications in process variable measurement and data transfer. When distance between the probe and the logging unit, or site conditions make hard wiring difficult or impractical DAN wireless connections offer a unique and convenient solution. Typically the range between a transmitter and receiver can be up to 2 kilometers depending upon the terrain and the obstructions and the antennas used at each end. With the use of selected antennas, the range may in some cases be extended to 10 kilometers.
Wireless DATA LOGGERS from DAN
New wireless transmitters and receivers available from Data Acquisition Networks have a number of benefits for people wishing to use data loggers.
1.Wireless units enable data loggers to be installed for a fraction of the cost. No ‘hard’ wiring is necessary and the wireless units can transmit up to 3km’s from the point at which data is collected to the DAN DM 01 command unit.
2.Wireless units provide flexibility. When wireless units are linked to a DAN DM01 data logger the various points at which data is captured can be varied.
3.Multiple locations can be monitored through one DM01 data logger.
4.The DAN DM01 data logger can be conveniently located near mains power thereby negating the need for alternative power such as solar, to be installed.
