Many temperature sensing applications in HVAC, appliance and other industries require that the sensor be mounted in or near areas that are subject to moisture due to condensation. Thermistors can be seriously affected by long term exposure to moisture. Over time, this condition will cause low or very erratic resistances due to sensor instability. In high moisture environments, its imperative that the internal construc- tion of the probe assembly is capable of sealing off all moisture paths to the thermistor. This design from MS provides for an excellent moisture seal between all parts of the system and deters water from entering the assembly. A unique internal construction is utilized as well as a special combina- tion of wire and epoxies to provide a moisture resistant seal to the outside environment and, thus protecting the Ordering Information thermistor sensing element. Material Wire MS Part Number R25 (W) Curve Color Any number of different thermistor curves and values A2253BT22P0 2,252 Z Orange can be accommodated as well as a broad range of housing and wire styles.
