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

10K Ohms @ 77 °F (25 °C) Type II Thermistor. The metal bell box (BB) configuration has a NEMA 3R rating and is designed for wet environments. This unit also 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. 

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.
