NTC Mounting Recommendations
- The sensor must be installed in a copper sleeve, to improve response time and to reduce setoff. The copper sleeve must be brazed on the surface of the pipe – see Figure 1.
- Protect the sensor from being moved or removed by transport, vibration etc.
- Use thermal compound to improve the heat transfer from the sleeve to the sensor. Thermal compounds must be approved for these temperature ranges.
- To reduce the impact of ambient temperature the pipe including the sensor or thermostat must be insulated.
- The sensor should be on the upper side of the pipe in a region of 45° as shown in Figure 2.
- If a sensor is placed after a bend it should be on the inner side of the bend at around 22.5° from the top of the pipe.
- Make sure the sensor cables are not installed along with other high voltage cables.
- For positioning of the sensor, please refer to Table 1 below.
Sensor| Position
---|---
Suction (compressor) temperature sensor| 120 mm from the compressor inlet
Liquid temperature sensor| 120 mm from the condenser or liquid receiver
Discharge temperature sensor (DLT)| 120 mm from the compressor outlet
Suction (evaporator) temperature| 400-600 mm from evaporator outlet (this must be validated by the OEM)
