Evergreen pushes custom PT100 and PT1000 RTD sensor selection

Dongguan Evergreen Technology says buyers comparing PT100 and PT1000 RTD sensors should weigh cable length, accuracy, wiring and operating conditions, not just price. The company is positioning its custom sensing process, ISO-backed manufacturing and traceability as a way to match sensor specs to industrial applications.

Why it matters: - PT100 and PT1000 choices affect signal quality, long cable runs, compatibility with measurement systems, and repeat sourcing for production batches. - Buyers in furnace control, battery-conversion and food-processing applications need sensor specifications that match the installation, not just the nominal part number. - Custom RTD design can reduce wiring mismatches, improve repeatability and make field installation more reliable.

What happened: - Dongguan Evergreen Technology Co., Ltd. outlined how it helps buyers choose between PT100 and PT1000 RTD sensors for industrial temperature sensing projects. - The company framed PT100 and PT1000 selection as part of a broader custom PT RTD sensor specification process. - Evergreen invited buyers to submit application conditions, sample requirements and specification details through the company's website.

The details: - PT100 sensors have a nominal resistance of 100 ohms at 0 degrees Celsius. - PT1000 sensors have a nominal resistance of 1000 ohms at 0 degrees Celsius. - The higher resistance of PT1000 can improve signal quality over long cable runs because the element produces a larger signal for the same temperature change. - Evergreen treats PT100, PT1000 and other custom resistance values as options within one Pt RTD sensor line. - RTD accuracy classes under IEC 60751 include Class A for calibration-grade or precision work and Class B for routine industrial monitoring. - Two-wire, three-wire and four-wire configurations affect measurement accuracy differently, and cable length adds another variable. - Evergreen says its engineering review addresses resistance value, wiring and installation factors before an order is placed. - Probe housing material, outer diameter and protection against water, pressure or vibration determine whether a sensor survives its operating environment. - Evergreen offers stainless steel housings as a standard option and adjusts outer diameter, housing material and protection level to fit the equipment. - The company also customizes temperature coefficient of resistance, cable insulation and connector configuration as part of one buildable part. - Evergreen supports projects from prototype sampling through wholesale-volume batch production and says its traceability runs from raw material to finished sensor. - RTD sensors suit applications that need a wide temperature range, strong interchangeability and long-term repeatability. - NTC thermistors are often better for cost-sensitive projects where fast response matters more than range. - PTC devices are typically used for overheat protection rather than continuous measurement. - Evergreen said its engineering team made that RTD-versus-NTC-versus-PTC comparison for a European industrial IoT sensor company that needed stable readings across a demanding temperature range. - The company operates under ISO 9001:2015 and ISO 14001:2015 management systems. - Quality control covers raw-material inspection through final performance testing in a roughly 13,000-square-meter production facility. - Evergreen recently expanded the production base with added cleanroom capacity and more automated testing and marking equipment. - The company says minimum order quantities and sample timing depend on the level of customization in the application.

Between the lines: - The message is that RTD procurement is becoming more application-specific, with buyers weighing environment and wiring architecture alongside sensor type. - Evergreen is positioning itself less as a parts seller and more as an engineering partner that can turn application details into a reproducible specification. - The emphasis on ISO systems, traceability and expanded automation suggests the company is targeting repeat OEM orders that need consistent batch-to-batch output.

What's next: - Buyers evaluating PT100 or PT1000 sensors are expected to define target resistance, accuracy class, operating range, cable length, wiring configuration, probe material, installation space and exposure conditions before requesting samples. - Evergreen says that information can be used to move a project toward a datasheet, sample and working specification. - The company is seeking inquiries for PT1000 RTD sensor solutions, PT100 temperature sensors and broader custom RTD supplier relationships.
