The PT100-5 is a compact and versatile probe-type Platinum Resistance Thermometer (PT100 RTD) featuring a stainless steel sensing tube without screw fittings. This design makes it an ideal choice for applications where the sensor is inserted directly into a thermowell, clamped in place, or embedded within equipment — offering a clean, low-profile installation without the need for threaded process connections. The PT100-5 is fully waterproof, making it well suited for wet or humid environments. Lead wire material and length are fully customisable, and the sensor is available in three probe diameters and multiple probe lengths to accommodate a wide range of installation geometries. Its straightforward construction and broad compatibility make it a popular choice for both OEM integration and field replacement applications.

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.

The PT100-3 is a widely used probe-type Platinum Resistance Thermometer (PT100 RTD) engineered for reliable and accurate temperature measurement in harsh industrial environments. The sensor integrates a rugged Form B connection box that protects internal wiring from dust, moisture, and mechanical damage, making it especially well suited for outdoor installations, chemical plants, and other demanding process environments. Compliant with EN 60751, the PT100-3 delivers a broad measurement range of −70 °C to +300 °C with high stability and repeatability. The sensor is compatible with a variety of standard process fittings — including 1/2 NPT, 1/2 BSP, 3/4 NPT, and M16 — enabling straightforward integration into existing pipelines and equipment. Probe diameter and length are fully customisable, allowing the PT100-3 to be tailored to virtually any installation requirement.

HART® is a worldwide known protocol which has been proven to be reliable and robust, TT-217 equipped with HART 7, put the electrical isolation between input and output and source, the configuration can be done via our free windows software, a HART to USB modem will be needed if you want to configure the temperature transmitter via PC, another option is to configure the unit by using various Hart field communicator.
