Johnson Controls Thermistors

Overview

Johnson Controls ST-W24 is an immersion temperature sensor that uses a 10K Type II NTC thermistor and a 4 in stainless steel probe with a 1/2 in NPT fitting for installation into a thermowell. The temperature element is sealed with a thermally conductive compound and the probe assembly is removable for replacement without draining the system. Typical applications include hydronic HVAC and process temperature monitoring. 10K Type II NTC thermistor sensing element for resistive temperature output 4 in stainless steel probe with temperature-conductive sealing compound and 1/2 in NPT thermowell fitting Probe assembly removable for replacement without draining the system; typically ships with 8 ft 24 AWG pigtail leads (non-polarized 2-wire) Product Highlights Immersion 10K Type II thermistor, 4 in stainless probe, 1/2 in NPT thermowell compatibility, removable probe assembly Product Information Standard Information Brand : JOHNSON CONTROLS Manufacturer Part Number : ST-W24 Technical Specifications Brand : Johnson Controls MPN : ST-W24 Product Type : Immersion temperature sensor Configuration : Immersion Sensor Type : Temperature sensor Sensing Element : 10K Type II NTC thermistor (10K-2 curve) Probe Material : Stainless steel Probe Length : 4 in Fitting : 1/2 in NPT Thermowell Material : Brass Mounting Type : Pipe mount / thermowell Accuracy : +/-0.36 F (+/-0.2 C) Operating Temperature Range : -40 to 221 F Wiring : Typically ships with 8 ft 24 AWG pigtail leads; non-polarized…
