Description
The ACI Immersion Series Thermistor features a 1/4in diameter stainless steel probe with two 14in, 22 AWG Etched Teflon colored lead wires (depending on the probe length ordered) to differentiate the different sensor types. The sensors in this series are manufactured using ACI’s double encapsulation process to eliminate the effects of moisture and to increase the response times using high quality, thermally conductive epoxy. The Immersion Series sensors include a welded thermowell “I” version but can be ordered without the welded thermowell “INW” version. The “INW” version includes a standard 1/4in NPS Male process thread to be used with an optional machined thermowell or in an existing thermowell application. Optional NEMA/IP rated enclosures and NIST certificates are available.
Applications:
- Chilled Water Systems
- Hot Water Systems
- Boilers
- Pumps
- Compressor
- Chillers
