Tailor the sensor to fit your application


The choice of materials, technologies, size, form  and capabilities of our sensor is very large. Our experts help you find the right ingredients for the ideal sensor solution for your application. The following examples are just a few of the infinite possibilities available to you:

Select from the available special sensor characteristics

Pt temperature sensor with metallized backside

Metallized backside (M)

  • Can be easily soldered onto a metallic surface - improvement of thermal coupling
  • Improved accuracy and response time
  • Also available as RealProbeTemp - sensor built-in into stainless steel probe
Invert welded and bent wires

Invert welded and bent wires (U)

  • For applications with limited space
  • Optimal for mounting the sensor to the bottom of a tube or a blind hole
  • Available with metallized backside and extended or directly welded wires
1E wired temperature sensor

Insulated wires, directly welded

  • 1E Enameled Cu-wire (Ø 0.2 mm), extended wires possible, with stripped insulation and pre-tinned wire ends for easy soldering
  • 2I Cu/Ag-wire or 2L Cu/Ag-stranded wire with PTFE-insulation for outstanding robustness, optimal for connector assemblies or for soldering, welding and crimping
Class A PW sensor up to 600 °C

Temperature measurement up to 600 °C in class A (PW sensor)

  • Precise measuring results up to IEC 60751 F0.15 (IST AG reference class A) within a wide operating temperature range from -200 °C to +600 °C

  • Combines the advantages of wire wound sensors (high accuracy in a wide temperature range) with the advantages of thin film sensors (robustness, small dimensions and very low hysteresis at an optimal price level)
  • Available in round ceramic housing (wire-wound sensors can easily be replaced)
  • The IST AG PW RTD sensor has been developed as an alternative to the traditional wire-wound sensors. The PW sensor combines the advantages of high accuracy and precision of the wire-wound sensors with the advantages of thin-film sensors that offer robustness, small dimensions and very low hysteresis at an optimal price level.


Sensor pairs and groups

Pairs and groups

  • For applications where the relative deviation between two or more sensors is crucial
PG sensor

Other temperature coeffiecients (standard: 3850 ppm/K)

  • 3911 ppm/K: GOST-norm compatible, IST AG term: PG
  • 3750 ppm/K: partly used in USA as common characteristic curve, IST AG term: PU
  • 3770 ppm/K: especially for automotive applications (up to +1000 °C)

Customer specific sensor adaptions

3-wire construction, extended wires

Extended 2- to 4-wire constructions

  • 2- to 4-wire constructions available (depending on application), sensors with extended wires or with wires directly welded to the chip
  • Various types of wire material and length are available
Shrink tube

Shrink tube

  • To avoid electrical short-circuits
  • Shrink tube covers one or more of the electrical contacts
  • Various solutions, e.g. shrink tubes placed over the extension point, shrink tubes covering the sensor chip or both in one solution
with M5 eyelet and PUR cable with 3-pin M8 plug


  • Sensor solutions with ready mounted connectors on wire ends for optimized assembly
  • Various types of connectors for different applications available
soldered to copper sheet, silicone glob top for protection

Sensors on sheets/disks

  • Sensors with metallized backside soldered to metal sheets, disks or in caps
  • Optimal thermal coupling 
  • No need of in-house soldering technology
PW in ceramic housing

Sensors in housings

  • Conventional way: after inserting the sensor, the housing is filled with an epoxy, polyurethane or silicone
  • Alternative: sensor is soldered to the bottom of the housing (better thermal contact, faster response time)
  • Housings are available with various diameters, lengths and materials
  • Easy integration in various applications - optimized assembly at the customer site
