The TC-K8 is a high-performance K-type thermocouple temperature sensor engineered for accuracy and durability in demanding high-temperature environments. Its defining feature is a robust ceramic sheath that provides exceptional resistance to thermal shock, chemical corrosion, and oxidation at elevated temperatures — making it the preferred choice for industrial processes such as kiln firing, furnace monitoring, and heat treatment operations. The sensor consists of two distinct probe sections: a stainless steel section that connects to the connection box, and a ceramic section that extends into the high-temperature measurement zone. This dual-material construction combines the mechanical strength and machinability of stainless steel with the superior thermal stability and chemical inertness of advanced ceramic materials. The integrated die-cast aluminum connection box provides a secure, weatherproof enclosure for the thermocouple terminals, protecting electrical connections from moisture, dust, and mechanical interference. Both the probe diameter and probe length of each section are fully customizable, enabling precise adaptation to virtually any industrial installation geometry. As part of the PIDMaxWell range of temperature measurement solutions, the TC-K8 is designed to integrate seamlessly with PID temperature controllers, temperature transmitters, and data acquisition systems.

The PIDMaxWell Quick Connectors series provides a complete range of thermocouple quick-connect plugs and sockets for use with K, J, T, E, and N type thermocouples and extension wires. Available in both standard and miniature sizes, and in nylon (up to 220 °C) or ceramic (up to 650 °C) body materials, the connectors are colour-coded in accordance with universal thermocouple standards — yellow for K, black for J, violet for E, blue for T, and orange for N — making polarity identification and type verification immediate and error-free in the field. Each connector is supplied as a matched male (plug) and female (socket) pair. The polarised pin geometry prevents incorrect insertion, and the screw-terminal wire clamps inside each connector body accept a wide range of thermocouple and extension wire gauges without soldering. The compact miniature format is ideal for space-constrained installations and portable instrumentation, while the standard format provides a more robust grip for fixed industrial installations. All connectors are fully customisable and available in bulk quantities to order.

CH102, CH402, CH702, CH902 is a very popular controller on the markets, comes with relay and SSR Drive output, relay and SSR Drive output at the same time, faciliated wiht different terminals, if you want to use the relay output, then connect your AC contractor or SSR with the relay output terminal, if you want to use SSR drive output, then connect your solid state relay with SSR Drive output terminal, with 1 alarm and works on wide range of power supply, works with thermocuple and RTD inputs despite the cost being very competetive.

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.

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.
