The ACI Thermistor Immersion Series features a 1⁄4” diameter stainless steel probe with two, 14 inch 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 proven double encapsulation process to eliminate the effects of moisture and to increase the response times using our high quality, thermally conductive epoxy. The immersion sensors include a welded thermowell “-I” version but can be ordered without the welded thermowell “-INW” version. The “INW” version includes a standard 1⁄2” 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 the back of the product data sheet.
