Waterproof Thermocouple / RTD Connection Head Terminal Box

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 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 TC-K14B is a fast-response K-type thermocouple engineered for applications where rapid, accurate temperature measurement is essential. Unlike conventional sheathed thermocouples, the TC-K14B features an exposed welded-bead junction with minimal thermal mass, enabling it to detect temperature changes within fractions of a second. This makes it the preferred choice for dynamic temperature monitoring tasks in research, testing, and industrial quality control environments. The sensor is constructed from a fine-gauge Chromel-Alumel (K-type) thermocouple wire pair, twisted together and insulated with a flexible fiberglass braid. The green-and-white color coding of the lead wire follows the international K-type thermocouple standard, providing clear polarity identification. The fiberglass insulation offers excellent thermal resistance and flexibility, allowing the sensor to be routed through confined spaces and around complex geometries without risk of insulation damage. At the instrument end, the TC-K14B is fitted with a standard miniature K-type quick-disconnect connector (green housing, labeled 'K NiCr+ / NiAl−'), which is compatible with a wide range of handheld thermometers, data loggers, and temperature indicators that accept the IEC 60584 / ANSI miniature thermocouple connector standard. The plug-and-play design eliminates the need for field wiring, enabling rapid deployment and sensor replacement without tools or specialist knowledge. The lead wire length is fully customizable, making the TC-K14B adaptable to installations where the measurement point is located at a significant distance from the instrument. As part of the PIDMaxWell range of temperature measurement solutions, the TC-K14B is designed to integrate seamlessly with PIDMaxWell PID temperature controllers, temperature transmitters, and compatible third-party instrumentation.  

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.
