7400 Pt100 Temperature Sensor

Brand: PR Electronics

  • Accuracy, IEC 60751 class A
  • Terminal head DIN 43729 form B
  • 1/2” RG connection
  • Stainless, acid-proof steel
  • Protection tube Ø 9 x 1
  • Temperature range -50°C to +400°C
Features
  • 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.
