It has been designed to accept most common temperature sensors including those from RTD and thermocouple sensors as well as slidewire and mV signals. The measured value is transmitted to the DIN Rail mounted base station (WRX900), this can accept signals from up to 16 WTX700 transmitters.
The measured signal is transmitted on the ISM (Industrial, Scientific and Medical) band of 868.4MHz. This frequency is virtually insensitive to external interferences and allows transmission even in a harsh industrial environment. The open air range is 300m.
