Description
The ACI 121469 is a precision 10kOhm thermistor well-mount temperature sensor designed for accurate fluid and pipe temperature measurement in HVAC, hydronic, and building automation applications. Featuring a 4″ insertion depth, this sensor is engineered to make solid thermal contact within standard immersion wells, delivering reliable and repeatable temperature data to building automation systems, controllers, and energy management platforms.
Key Features
- 10kOhm thermistor element for high-accuracy temperature sensing
- 4″ insertion depth for compatibility with standard immersion/thermowell fittings
- Protective enclosure shields the sensor head from moisture, dust, and mechanical damage
- Designed for use in hydronic piping, boiler systems, chilled water loops, and process fluid monitoring
- Easy field installation — inserts directly into a matching thermowell without draining the system
- Compatible with a wide range of BAS controllers, DDC systems, and energy management platforms accepting 10kOhm NTC thermistor inputs
- Durable construction suitable for commercial and light industrial HVAC environments
Applications
- Hydronic heating and cooling systems
- Boiler supply and return temperature monitoring
- Chilled water and condenser water loops
- Building automation and DDC control systems
- Energy management and sub-metering installations
