The polycarbonate NEMA 4X, immersion configuration is designed for wet environments and adds a level of corrosion resistance. It has male 1/2 inch NPT threads and the sensing element is double encapsulated to avoid sensor failures caused by moisture infiltration. ACI also standardizes with etched Teflon lead wires and a two part well is included with this configuration. 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: 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.
- Negative temperature coefficient
- Double encapsulated sensor
