Status launches unique wireless temperature monitoring system

10 January 2011

Status Instruments has launched a new wireless temperature and transmitter and receiver for industrial applications where installing hard wired technology can be costly and disruptive.

The new WX series consists of the WTX700 wireless temperature transmitter and the WRX 900 DIN rail receiver. Together, they provide an adaptable option for all types of facilities, including the harshest of industrial environments.

The WTX700 transmitter accepts RTD and thermocouple sensors as well as slidewire and mV signals. It is powered using a 3.6V Lithium battery with a lifespan of up to 3 years depending on the transmission rate. Two choices of connecting heads allow for maximum flexibility, the aluminium SCH11 is sensor-mounted while the ABS plastic SCH4 can be sensor-mounted or surface-mounted, particularly valuable when used with a flying lead sensor.

Data gathered by up to 16 WTX700 transmitters is sent to the WRX900 DIN Rail receiver. The receiver converts up to four temperature values into isolated current or voltage signals or into two current signals and two relay alarm signals. Any one of the in-head transmitters can be linked to any one of the analogue or relay outputs and all are available via the RS485 digital interface.

An optional antenna mounting bracket and extension cable is available for cabinet installations or to optimise signal strength. The WX Series has an open air range of up to 300m, making it a valuable resource for large-scale operations.

The data signal is transmitted on the ISM band (Industrial Scientific and Medical Band) of 868,4MHz, a frequency resistant to external interferences, making the WX Series suitable for use in the harshest of industrial environments.
