Modbus Surface Temperature Sensor ANDOBTF/MD RS485 sensor is designed for measuring the temperature on plain surfaces such as windows. The feeler is made of aluminum and can be mounted to the respective surface with the borehole (4,1 mm) located on the upper half of the sensor. The sensors are equipped with a standardized 0…10 V or 4…20mA output and can be connected to any PLC or DDC.
Additional options for sensor ANDOBTF/MD (surcharges):
- display,
- power supply cord per meter (PVC),
- relay.
Sensor type:
- Modbus sensor
Alternative sensor versions:
- Passive Surface Temperature Sensor ANDOBTF,
- Active Surface Temperature Sensor ANDOBTF/MU.
