A/1K-2W-FA-8'-EH - 1000 Ohms @ 32 degrees F ( platinum RTD sensing element) with a 0.00385 temperature coefficient. This European style enclosure flexible averaging configuration provides an averaged output based on the cable length ordered.  The European style enclosure locks out moisture with a gasketed cover and watertight fitting which makes it suitable for wet environments.  ACI averaging temperature sensors are designed for HVAC or Building Automation Systems.  Specific applications include: zone control air handling unit and large sized ducts. 

A/1K-2W-I-2.5"-GD - The galvanized metal box with well configuration has male 1/2" NPT threads. The sensing element is double encapsulated to avoid sensor failures caused by moisture infiltration. ACI also standardizes with etched Teflon lead wires and two part wells are included for this part. ACI immersion temperature sensors are designed for HVAC Building Automation System and light industrial applications. Specific applications include: chiller hot water system tank and boilers. NOTE: 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.
