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.
