A new, current-saving measuring- system makes it possible to eva- luate 3 sensors with a transducer that is supplied by a loop 4-20 mA. This design is protected. The sensors Pt100 are connected in 2-wire-technique. The output signal is a current 4-20 mA. The value of the output current corresponds with the temperature of the hottest sensor. Application: Recording of temperatures at e.g. motors, generators, transformers or compressors and forward them to relais or controls for evaluation. In difference to PTC with sensors Pt100 a adjustable switching temperature can be realized. The temperature protection can be adapted to the requirements at any time. Optimal operation and longer life by intelligent management pos- sible. E.g. no start at high motor temperatures. The cast-resign sealed electro- nics can be used at temperatures up to 85 °C and thus be placed near the sensors, e.g. in the terminal box of a motor. This reduces influence of EMC and line resistance. The signal 4-20 mA can be transmitted over long distances 1 - 3 x Pt 100 DIN 43 760/IEC 751 without compensation of line resistance DC 4...20 mA DC 12...32 V class 2,5 0,025 %/°K IEC 770, Tu = 23 °C ± 5 °C, Us = DC 24 V ± 1 V -20...+85 °C TMU300 Design 420 with terminals 60 x 55 x 32 mm Screw mounting 2 x M4 IP 40 / IP 20 approx. 70 g Technical Data Input Output Current output Voltage loop Error Temperature coefficient Reference conditions adm. operating temperature Dimensions (W x H x D) Attachment Protection housing / terminals Weight 2016-10-19 TMU300 Part number: T236076
