The PT100-8 is a probe-type Platinum Resistance Thermometer (PT100 RTD) distinguished by its adjustable insertion depth — a key feature that sets it apart from fixed-length sensors. A stainless steel compression fitting is integrated into the assembly, forming a liquid-tight or pressure-tight seal against the process wall while allowing the operator to slide and lock the probe at any desired insertion depth before or after installation. This eliminates the need to specify a fixed immersion length at the time of ordering and greatly simplifies retrofitting into existing equipment. The probe is constructed from 304 stainless steel and is available in diameters of 4 mm, 5 mm, and 6 mm. The lead cable is shielded with a metal braid and covered with PTFE insulation, delivering low noise, high mechanical strength, and excellent resistance to elevated temperatures. The PT100-8 is compatible with a wide range of process fittings — including NPT, BSP, and metric threads — and is available in a waterproof configuration, making it suitable for measuring the temperature of both air and liquids across diverse industrial environments.

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.
