Our SMPT range of thin-film 2-wire platinum RTD elements are some of the smallest available and conform to DIN EN 60751 (IEC 751).
Based on a 2mm x 2mm x 0.8mm thin ceramic substrate, the Pt100 (or Pt500 or Pt1000) elements are laser-trimmed for accuracy and then sealed in glass to ensure complete integrity. They are highly stable and suitable for use up to 500oC (Class B) or 300oC (Class A).
R0 values of 100, 500 and 1000 ohms are available with Class A and B tolerances.

For applications where a high water-proof integrity is required, our IP68 Pt100 (or Pt500 or Pt1000) sensors ensure that water ingress will not be a problem. Moulded in TPE, the sensing portion is 5mm dia. x 20mm long and is available in single or double-insulated formats. The double-insulated versions offer a dielectric strength up to 3.75kV.
Suitable for continuous use from -50/+110°C, they can also be used to 125°C for periods of up to 3000 hours.
By utilising one of our platinum RTD elements, we can supply Pt100, Pt500 or Pt1000 class B sensors with an accuracy of +/-0.15K. 4 wire Class A are also available where an even higher degree of accuracy is required.

Our SKTY linear PTC elements offer a solution for the once common KTY series. The SKTY elements are mounted on a small 3mm x 6mm p.c.b. and are available with R25 values of 1kohm and 2kohm with +/-1% tolerances.
The SKTYs can also be supplied as IP68 rated moulded sensors (see above) with single or double-insulated leads. Other probe formats are also available to order.

To compliment the range of IP68 sensors, a wide range of mounting options are available by employing integral or separable thermowell systems in stainless steel.
