Ex i RTD sensor
PR 7600
- Interchangeable insert
- Protective tube Ø9 mm
- G ½ process connector
- 4-wire sensor element
- Accuracy, IEC 60751 class A (-30...300°C)
- Measuring range -50...500°C
Application
- The 7600 is a general purpose intrinsically safe RTD temperature sensor designed for use in hazardous areas where explosive gas or dust atmospheres may occur.
- Suitable for use in chemical and pharmaceutical industries, refineries, power generation, and offshore installations requiring certified equipment for Zone 0/1 and Zone 20/21 applications.
- Intended for temperature measurement in gaseous and liquid media within the process temperature range of -30...300°C.
Technical characteristics
- The 7600 model features an interchangeable Pt100 class A measurement insert, ensuring easy replacement and calibration without process interruption.
- The protective tube is made of acid-proof stainless steel EN 1.4571/1.4404 / AISI 316L/TI, offering high mechanical strength and corrosion resistance.
- A ½" G process connection is welded to the protecting tube for a secure and tight installation.
- An optional cooling extension is available for applications where the process temperature or ambient conditions require additional separation from the terminal head.
- The terminal head is a DIN 43729 form B housing in light-alloy metal, finished with corrosion-resistant industrial lacquer.

- Labelling: Ex II 1/2 G Ex ia IIC T6–T1, Ga/Gb Ex II 1/2 D Ex ia IIIC Tₓ Da/Db
- Input parameters: Ui = 30 V, Ii = 101 mA, Pi = 750 mW, Ci, Li = negligible
- The sensor is designed for installation in hazardous gas (Zone 0/1) and dust (Zone 20/21) environments in accordance with intrinsic safety standards.
Electrical connection
- Supplied with a 4-wire configuration, allowing for lead resistance compensation and high-accuracy temperature measurement when used with an Ex i-certified transmitter.
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.
