Wall mount RTD sensor
PR 7872
- Stainless steel AISI 316Ti
- Optional remote TBT cable sensor
- M12 / PG9 electrical connector
- Pt100 class A / class B 1/10
- Measuring range -196…250°C / -50…100°C
Application
- The stainless wall mount RTD temperature sensor is designed for accurate air temperature measurement in both indoor and outdoor environments.
- It is suitable for climate and ventilation systems, damp rooms, freezer compartments, and storage containers, where precise and reliable temperature control is essential.
- The sensor delivers dependable performance even in environments with high humidity, condensation, or temperature fluctuations.
- Marine certifications: DNV, BV, LR, ClassNK, RINA
Technical characteristics
- Choice of housing with PG9, M12, or raw housing for customer installation of the sensor element.
- Versions with Pt100 sensors available in combinations of PG9 and M12 connection types, with fixed sensor element.
- The outer protective sheath and process attachment are made from acid-proof stainless steel, offering high resistance to corrosion, shock, and vibration. The robust construction ensures consistent performance in indoor, outdoor, and cold storage applications.
- With a protection class of IP67, the sensor is dust-tight and resistant to water ingress, making it ideal for harsh or humid environments.
Electrical connection
- The sensor is designed for simple wall-mount installation and provides a reliable electrical interface for integration with standard control and monitoring systems.
- Connection options include a PG9 cable gland or an M12 connector, depending on configuration.
Options
- Combine with the PR 5300 / PR 5400 series transmitter - we can deliver the transmitter pre-mounted to the sensor.
- Optional ceramic socket available for connection to externally installed transmitters.
- Material certificate, certificate of origin, certificate of conformity and calibration reports can be supplied when ordered together with the sensor.
