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 PT100-12 is a PT100 Platinum Resistance Thermometer featuring an adjustable compression fitting combined with a robust Form B aluminium connection box (connection head). This combination delivers two key advantages in a single assembly: the compression fitting allows the probe insertion depth to be set and locked at any position within the fitting stroke, eliminating the need for custom-length probes during installation; and the sealed connection box provides a weather-resistant, vibration-tolerant housing for field wiring that is well suited to demanding industrial environments. The sensor complies with EN 60751 and covers a temperature range of −70 °C to +300 °C, making it suitable for a wide spectrum of process and industrial applications. The stainless steel probe is available in three diameters — 4 mm, 5 mm, and 6 mm — and three standard lengths of 50 mm, 100 mm, and 150 mm, all of which can be customised to order. Adjustable process fittings are available in ½ NPT, ¼ NPT, and ¼ BSP thread forms, enabling direct installation into standard process pipework and vessels without adapters. The connection box accepts standard conduit entries, and the sensor ships without lead wire, with all field connections made inside the terminal block housed within the connection box.

The NTC10K Series is a compact, high-precision Negative Temperature Coefficient (NTC) thermistor temperature sensor housed in a rugged stainless steel M8 screw-body probe. Designed for direct installation into threaded ports on pipework, tanks, heat exchangers, and machinery, this sensor delivers accurate, low-cost temperature measurement across a wide operating range without the need for signal conditioning or cold-junction compensation.At the heart of the sensor is a precision NTC thermistor element with a nominal resistance of 10 kΩ at 25 °C and a B-value (B25/100) of 3950 K ± 1%. The thermistor element is encapsulated within a 4 mm diameter stainless steel probe, sealed with high-temperature epoxy resin to ensure moisture ingress protection. The M8 threaded body incorporates a high-temperature silicone gasket to provide a leak-proof seal when installed into a threaded port. A 150 mm flat silicone lead wire terminates in a standard 2-pin SMP (Micro-Fit style) connector for fast, tool-free connection to the host system.The NTC10K series is fully compatible with Maxwell's range of temperature controllers, as well as third-party controllers, HVAC control boards, and microcontroller-based systems that accept a passive NTC thermistor input. The sensor's small probe diameter, short lead wire, and plug-and-play connector make it an ideal drop-in component for OEM equipment manufacturers and system integrators.

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.

MF43H is a touch screen ramp and soak controller, the conventional ramp and soak controllers or some call it profile controllers on the markets are configured via set buttons on the front panel. end user have to go through layers upon layers of parmaeters and navigate through different parameter during the configuration process. the process could be painful and stressed and often times lead to less efficient and frustration. the configuration with our touch screen ramp and soak controller is much more easier, it's easier for end user to pick up the process as they operate the controller like a cell phone. below are some of the basic features with this touch screen ramp and soak profile controller
