General purpose RTD sensor - fixed insert
PR 7400
- Terminal head DIN 43729 form B
- Protective tube Ø9 mm
- G ½ process connector
- 3-wire sensor element
- Accuracy, IEC 60751 class A
- Temperature range -50...+400°C
Application
- Temperature measurement in industrial systems, e.g. in the food, chemical and pharmaceutical industries, cold storage plants, district heating, power plants, refineries and ships.
- Temperature measurement in gas and floating media.
- Marine certifications: DNV, BV, LR, ClassNK, RINA
Technical characteristics
- The 7400 comes with a fixed measurement insert.
- The sensor element is a thin film platinum resistor - Pt100 - trimmed at a laboratory to comply with the resistance values of the standard IEC 60751, class A. The advantage of a thin film element is an ultra short reaction time. The Pt100 element is electrically isolated from the protecting tube and terminal head.
- The protecting tube is Ø 9 x 1 mm stainless, acid-proof steel W no. 1.4571 / AISI 316TI, filled with aluminum oxide powder. A 1/2” RG thread nipple is welded on the protecting tube with a packing sheet of Ø 30 and span 30.
- The terminal head is a standard DIN 43729 form B housing produced in light-alloy metal, protected against corrosion through strong industrial lacquering.
- The sensor is available with or without cooling extension to keep the terminal head clear of isolated surfaces.
Electrical connection
- Each sensor is delivered with a three-wire connection which allows cable compensation to the sensor element.
Option
- 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.
