JUMO 537805 Widerstandsthermometer, Funk, Gri

The radio transmitter module with M 12 plug connection basically allows the connection of various resistance thermometers, which are designed with measuring insert 1x Pt1000 according to DIN EN 60751 (tolerance class A) in three-wire technology and M 12 plug connection. Thus extended temperature ranges from -200 up to +600 °C can be transmitted. The transmitter electronics are located in an oil and acid resistant housing, whose ambient temperature may be in the range of -25 to +125 °C. The measured values are transmitted wirelessly via an integrated Wtrans transmitter to the appropriate Wtrans receivers, where they are displayed and are available in digital form at the RS485 interface and as an analog output. The radio transmitter module is suitable therefore everywhere, where one places flexibility to the temperature sensor selection and additionally a high wiring expenditure would like to avoid. The protection class is IP67. A long-life lithium battery 3.6 V is used for the 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. One receiver version can signal different alarms at two relay outputs. If the antenna wall mount with the 3 m long antenna cable is used on the receiver side, the range in free field is 300 m. A setup program is available as an accessory for easy configuration and parameterization of the Wtrans measuring system on a PC. As an option, the OnlineChart function can be used to record measured values on the PC.
