100 Ohms @ 32 degrees F ( platinum RTD sensing element) with a 0.00385 temperature coefficient in a three wire configuration. The polycarbonate NEMA 4X immersion (4X) configuration is designed for wet environments and adds a level of corrosion resistance and includes a two-piece 304 stainless steel thermowell which has male 1/2 inch NPT threads. The wells are milled to tight tolerances so there is maximum temperature transfer and this eliminates the need for thermal grease. The sensing element is double encapsulated to avoid sensor failures caused by moisture infiltration.
