I provide 4mm Rtd Pt100 sensors engineered for precision and durability in demanding industrial processes. With compact 4mm diameter probes and high-reliability Pt100 elements, these sensors deliver stable readings across wide temp ranges and steady long-term performance. I offer ODM solutions to tailor connectors, sheathing, and calibration to your exact requirements, plus Factory direct pricing and fast lead times to keep your production on track. My sensors are suitable for food, pharma, chemical, and manufacturing environments, with corrosion-resistant sheaths and robust termination options. I assemble to spec, test thoroughly, and ship ready for integration into your control system. Whether you need custom connector types, cable lengths, or calibration certificates, I will work with you to meet your spec and scale your implementation. Choose a partner who values quality, traceability, and responsive service, and you’ll get a reliable sensing solution you can trust for years to come.
Global buyers seek compact yet reliable 4mm RTD Pt100 probes that deliver precise signals in tight spaces. The 4mm form factor supports fast response while withstanding demanding processes. Adhering to IEC 60751, these sensors offer 100 Ω at 0 °C with Class A or Class B tolerances, and are available with corrosion-resistant sheaths (304/316 stainless steel) or alternative materials for high temperature or chemical environments. Custom solutions cover end fittings, tip geometry, lead lengths, and connector options to fit your installation. Choices include exposed, grounded, or insulated tips, various IP ratings, and pre-wired assemblies with M12 or DIN connectors. Optional traceable calibration, batch records, and tailored tolerances help meet food, pharmaceutical, chemical, or energy sector needs. With scalable production and reliable QA, you can secure steady supply and consistent performance across global operations.
