Mobrey MSP-RTP External Temperature Sensor Part No : MSP-RTP For use with ultrasonic transmitters MSP400RH and MSP900GH Introduction For transmitter installations where the integral temperature sensor is not representative of the air / medium temperature in the process, the use of the external temperature sensor improves accuracy. Sensor Specification 316 Stainless steel body with two locknuts, M8 thread, 6 mm maximum panel thickness. Sensor working temperature -40 to 85 °C, cable working temperature -20 to 80 °C. Cable 5 m long, single twisted pair. Note: When connected to a MSP900GH intrinsically safe transmitter, this sensor is classif edas'simple apparatus’ according to EN 50020 paragraph 5.4. Temperature class T6, -20 °C < Ta < 80 °C delta mobrey

1. Connect the two sensor wires to terminals 7 and 8 of the transmitter; polarity is not important. See diagram below; also refer to Transmitter Installation Manual. Ensure use of a suitably IP rated cable gland to maintain the IP rating of the transmitter. 2. Mount the sensor between the transmitter and the liquid level, to measure the air / medium temperature at a representative point. 3. Avoid allowing the sensor to become submerged. 4. Do not mount the sensor near a heat source or in direct sunlight. 5. For the optimum response to temperature change, do not mount directly onto a large thermal...
