Engineered for accuracy and longevity, our Type K Thermocouple provides consistent temperature readings, making it an ideal solution for critical thermal processes.

This is a PID temperature controller works with universal signal, thermocouple, RTD and analog signals, comes with several options on the output, popular choices is Relay, SSR Drive and 4-20mA, 0-10VDC output, fast sampling rate and built-in timers optional, for system intergration purpose, you can choose the RS-485 modbus feature, up to 2 alarms, heating and cooling control configurable, vivid LCD display. offers standard PID control mode and ON/OFF control mode. fuzzy logic pid algorithm

The MWH300F-692 is a versatile dual-mode intelligent controller supporting both PID temperature control (thermocouple/RTD) and SCR process control (analog voltage/current). It features real-time 3-phase current/voltage monitoring, a bright dual-row digital display, and comprehensive safety protections including over-temperature, over-current cut-off, heater break/short alarm, and 3-phase unbalance detection. With RS-485 communication, PID auto-tuning, and a rugged industrial design, it ensures precise and reliable performance in harsh environments.  

This is a single phase SCR power regulators and temperature controllers 2 in 1 units, in a typical heating system, you would need a temperature controller and a SCR power regulators, and they are two separate devices, we go further and build this two devices in one package, this saves a lot of efforts for panel builders when it comes down to wiring, and RS-485 modbus is a standard feature, controller can be integrated to systems with HMI or PLC etc. the load can be directed wired to this thyristor power regulators, and it works with all kinds of inputs, Thermocuple, RTD, analog signal

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.

Three-Phase Intelligent SCR Power Regulator The Maxwell TC-200S Series is an industrial-grade, three-phase intelligent SCR (Silicon Controlled Rectifier) power regulator designed for precise, stepless control of resistive heating loads in demanding industrial environments. Manufactured by Maxwell Automation Technology Co., Ltd. under the PIDMaxWell brand, the TC-200S combines a fully digital control architecture with an integrated dual-row LED display, multi-function indicator LEDs, and a front-panel keypad, enabling operators to monitor process parameters and adjust output settings directly without external programming tools. The regulator accepts a wide range of analogue control input signals — including 4–20 mA, 0–20 mA, 0–5 VDC, 0–10 VDC, 1–5 VDC, and 2–10 VDC — and features automatic phase detection, making it straightforward to integrate into new or existing control systems. An integrated soft-start (ramp) function eliminates inrush current surges at power-on, protecting both the SCR modules and the connected heating elements from thermal shock. When the heat-sink temperature exceeds the user-defined alarm threshold (AL1), the unit automatically reduces output power to a configurable safe level (EOP), maintaining process continuity while safeguarding the internal SCR modules from thermal damage. An optional RS-485 communication interface with Modbus-RTU protocol enables seamless integration into SCADA systems, PLCs, DCS, and industrial IoT networks. The TC-200S supports auto/manual bumpless transfer, run/stop control, and configurable minimum and maximum output limits, providing the flexibility required for a wide range of industrial heating and process control applications. Rated current options of 100 A, 125 A, 150 A, 175 A, 200 A, and 225 A cover load capacities from 48 kW to 190 kW (three-phase), making the TC-200S suitable for small laboratory ovens through to large industrial electric furnaces.
