The PT100-14 is a bolt-on PT100 Platinum Resistance Thermometer designed for direct surface temperature measurement. The sensor element is integrated into a ring (eye) terminal lug that is bolted or screwed directly onto the surface to be measured — such as a motor casing, heat sink, pipe outer wall, bearing housing, or structural component — ensuring intimate thermal contact without the need for a thermowell, probe pocket, or adhesive. This makes the PT100-14 an exceptionally convenient and cost-effective solution wherever surface temperature monitoring is required.

The ring terminal inner diameter is available in 6 mm or 8 mm as standard, and can be customised to match any bolt or screw size specified by the customer. The sensor is supplied with a stainless steel braided cable for mechanical protection and EMI shielding, and the lead wire material is fully selectable from stainless steel braid, silicone, fiberglass, or Teflon to suit the thermal and chemical conditions of the installation environment. Standard cable lengths are 2 m, 3 m, and 5 m, with custom lengths available on request. The sensor is available in temperature ranges up to 100 °C, 200 °C, or 300 °C.
