The insertable resistance thermometer with measuring element 1x Pt1000 according to DIN EN 60751 (tolerance class A) is designed in three-wire technology and is intended for temperatures from -30 to +260 °C. The measurement values are transmitted wirelessly via an integrated Wtrans transmitter to the corresponding Wtrans receivers, where they are displayed and are available in digital form at the RS485 interface as well as an analog output.

The resistance thermometer is suitable for applications where high wiring effort should be avoided or is not possible. A receiver variant can signal different alarms at two relay outputs. The transmitting electronics of the resistance thermometer are shockproof and housed in an oil- and acid-resistant casing, which can operate in ambient temperatures ranging from -30 to +85 °C. The protection class is IP67.

A long-lasting 3.6 V lithium battery is used for power supply. The radio frequencies of the Wtrans measuring system (868.4 MHz) are largely insensitive to external interference and allow transmission even in harsh industrial environments. When using the antenna wall mount with the 3 m long antenna cable on the receiver side, the range in open field is 300 m.

The 4.0 mm thick stainless steel protection tube is equipped with a central measuring tip (angle 25°). The insertion length is 100 mm. For easy configuration and parameterization of the Wtrans measuring system on a PC, a setup program is available as an accessory. Optionally, measurement data can be recorded on a PC using the OnlineChart function. EAN: 4053877011347.
