The Jumo Wtrans RF temperature probe, type T01.G1, for mobile or stationary measurement of temperature at movable and fixed locations, and the matching T01.EC1 multifunction receiver, were developed so that temperature measurements can be transmitted without needing any wiring. The transmitter is built into the probe handle, and is protected by a waterproof housing. The transmission frequencies which are used are largely insensitive to external sources of interference, and permit transmission even in tough industrial environments. The transmitter is designed as an insertion probe. The probe is available with fitting lengths from 50 to 500 mm, and includes a platinum chip resistor as the sensing element. The transmitter can handle a temperature range from -30 to +260 °C. The permissible ambient temperature range for the eletronics is -30 to +85 °C. In order to take account of the presently applicable legislation and comply with the existing regulations and industrial standards, an RF solution was selected that uses a proprietary protocol in the ISM band on frequencies of 868 MHz (Europe) or 915 MHz (Australia, Canada, New Zealand, USA).
