3.3.1 External temperature sensor
The MSP400RH transmitter will accept an input from a Mobrey external temperature sensor.
Order part number
This is a thermistor based temperature sensor specifically designed for use with the MSP400RH transmitter.
Full installation instructions are supplied with the temperature sensor, but note that it should be mounted out of direct sunlight in a position such that it can give a representative reading of the air temperature between the liquid surface and the MSP400RH transmitter.
3.3.2 After completing the wiring
Ensure all cable glands / blanking plugs and seals are in good condition after wiring to maintain the weatherproof rating of the transmitter.
Check that the cover seal is in good condition and not twisted or misaligned in the seal location groove. When replacing the cover, tighten the 3 cover screws evenly to exert uniform pressure on the cover seal.
