- Transducers for motor protection TMU300 are transducers for 1-3 sensors Pt100 (RTD). A new, current-saving measuringsystem makes it possible to evaluate 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.
- connection of 1-3 sensors Pt 100 in 2-wire-technique
- measuring range 0...200 °C
- automatic selection of warmest sensor
- I < 3,5 mA at short circuit in any sensor
- I > 25 mA at interruption in any sensor
- analog output 4-20 mA
- rated ambient temperature up to 85 °C
- no supply voltage required (supplied by 4-20 mA loop)
- with sealed-in electronics
