ACIA/CP-I-4-GD, ACI,

10K Ohms @ 77 °F (25 °C) Type II Thermistor. The galvanized metal immersion (GD) configuration 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. 

ACI immersion temperature sensors are designed for HVAC, Building Automation Systems, and light industrial applications.  Specific applications include: chillers, hot water systems, tanks, and boilers.  NOTE: Standard (welded) thermowells are not intended for moving water or high pressure service. Fluid velocity and wake frequency are primary factors in well failure. Machined thermowells should be used in these types of applications.
