The transmission electronics of the RTD temperature probes are placed in the case so that they are vibration-proof; the case is oil-resistant and acid-proof. The ambient temperature of the case may either be from -30 to +85 °C or -25 to +125 °C. The protection type is IP67. A durable lithium battery with 3.6 V is used for voltage supply.
The radio frequencies of the Wtrans measuring system (868.4 MHz or 915 MHz) are largely impervious to external interferences and allow transmission even in a rough industrial environment. When using the antenna wall holder with the 3 meter cable for the receiver then the maximum open air range is 300 m.
The Wtrans transmitter is used in connection with a Wtrans receiver for stationary or mobile detection of temperatures within the operating range of -30 to +260 °C or -200 to +600 °C. This measured temperature value is transmitted wirelessly to the receiver of the Wtrans measuring system; here it is displayed and available digitally at the RS485 interface as well as an analog output. One receiver variant can signal various alarms on two relay outputs.
The stainless steel protection tube with the Pt1000 temperature sensor according to DIN EN 60751, class A in a three-wire circuit is available with a flat, oblique, or centered probe tip. The insertion length extends from 30 to 10000 mm. Variants are available with an extension tube or an M12 × 1 plug connection to connect Pt1000 RTD temperature probes.
