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 TC-K1 / TC-J1 / TC-T1 Series Screw-In Nozzle Thermocouple is a compact, robust, and highly versatile temperature sensing solution engineered for direct installation into threaded ports on machinery, pipelines, and process equipment. By leveraging the well-established Seebeck effect — in which two dissimilar metal conductors joined at one end generate a measurable electromotive force (EMF) proportional to the temperature difference between the hot junction and the cold (reference) junction — this sensor delivers reliable, real-time temperature readings across a broad operating range. Designed for demanding industrial environments, the TC-K1 / TC-J1 / TC-T1 series features a fully threaded stainless steel body that enables secure, leak-proof installation into standard metric (M6, M8) and pipe-thread (1/4 NPT, 1/4 BSP) fittings. The sensor is available in three internationally recognised thermocouple calibrations — Type K (Chromel/Alumel), Type J (Iron/Constantan), and Type T (Copper/Constantan) — to suit a wide spectrum of temperature measurement requirements. Lead wire material, length, and junction type are all fully customisable, making this series an ideal choice for OEM integrators and system designers seeking a drop-in thermal sensing component.  

The Maxwell TT-501 Series is a robust and highly versatile threaded thermocouple temperature transmitter engineered for demanding industrial environments. Housed in a rugged, explosion-proof aluminum alloy enclosure, this transmitter delivers reliable and accurate temperature measurement across a wide range of process conditions. An integrated digital display provides clear, on-site readings, while the RS485 (Modbus RTU) communication output enables seamless integration into modern PLC-based control systems, SCADA networks, and building management systems. With its highly customizable design — featuring multiple thread options (M6, M8, 1/4 BSP, 1/4 NPT), a selection of premium probe materials (304, 316, and 310 stainless steel, brass, and aluminum), and a comprehensive range of lead wire materials — the TT-501 can be precisely configured to meet the exact requirements of any installation. Both grounded and ungrounded junction configurations are available, offering a choice between faster thermal response and electrical isolation to suit the specific demands of each application.
