For hot water boiler applications, the Boiler Probe for OEMs has been released by Measurement Specialities. It contains an NTC thermistor soldered on an industry standard 2.5 mm connector. RoHS compliant, the probe features a fast response time and an operating temperature range from -40 to 125 °C. The durable brass housing provides 1/8 BSPF for ease of installation and replacement. Optional threads are available for custom designs. Typical performance for the probes is 10,000 Ohms resistance at 25 °C. A reliable ±1 °C tolerance is held over 25 to 85 °C. Beta value is 3976 K with a variance of ±1%. Custom tolerances are available upon request as are ranges of R/T curves. The probe withstands harsh environments and has been tested to withstand rapid temperature cycling. Both Nickel and Platinum can be accommodated for special applications requiring RTD elements.
