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.

Operation interface in English, Chinese and Spanish.

The PT100-9 is a tri-clamp liquid-tight Platinum Resistance Thermometer (PT100 RTD) engineered for reliable and accurate temperature measurement in sanitary and process environments where a secure, leak-proof connection is essential. The sensor features a stainless steel flanged tri-clamp fitting that forms a robust liquid-tight seal, making it ideally suited for food processing, dairy, brewing, pharmaceutical, and chemical applications where hygiene and contamination prevention are paramount. The probe is constructed from stainless steel and is available in three diameters (4 mm, 5 mm, and 6 mm) with probe lengths of 30 mm, 40 mm, or 50 mm, all of which can be customised to meet specific installation requirements. Lead wire material is fully selectable — stainless steel braid, silicone, fiberglass, or Teflon — allowing the sensor to be matched to the thermal and chemical conditions of the surrounding environment. Lead wire length is available in 2 m, 3 m, or 5 m. The “-TC” suffix in the ordering code designates the tri-clamp liquid-tight connection, clearly distinguishing this series from standard probe-type RTDs.

The Maxwell SCR20CA Series is a highly integrated, single-phase AC power controller designed for advanced feedback control and precise voltage regulation. Built around a high-power thyristor (SCR) chip, this compact unit incorporates a digital phase-shift control circuit alongside highly accurate output voltage and current measurement systems. A standout feature of the SCR20CA is its multi-functionality: users can seamlessly switch between constant voltage, constant current, and constant power control modes directly via the digital panel or communication interface. Equipped with true RMS sampling and a fully isolated measurement system, it ensures safe and reliable operation. With built-in RS-485 Modbus RTU communication, pluggable control terminals, and comprehensive protection mechanisms, the SCR20CA is an ideal solution for modern, automated industrial heating and power control applications.
