Transmitter and receiver for harsh environments

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 harsh industrial environments.

The WTX700 transmitter accepts RTD and thermocouple sensors as well as slide-wire and mV signals.

It is powered using a 3.6V lithium battery with a lifespan of up to three 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, which is ideal 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 suitable for large-scale operations.

The data signal is transmitted on the Industrial Scientific and Medical (ISM) band of 868,4MHz, a frequency resistant to external interferences.
