Description
Overview
The KMC Controls STE-1404 is a rigid duct-mount temperature sensor designed for reliable air temperature measurement in commercial HVAC and building automation applications. Featuring a 10K ohm thermistor sensing element housed in a durable 12-inch rigid insertion probe, this sensor delivers accurate, repeatable readings directly within the airstream of supply, return, or mixed-air ductwork.
Key Features
- 10K ohm thermistor sensing element for precise temperature detection
- 12-inch rigid insertion probe for deep duct penetration and accurate airstream sampling
- Rigid probe construction provides stable, vibration-resistant installation
- Designed for duct-mount applications in commercial HVAC systems
- Compatible with KMC Controls building automation controllers and a wide range of third-party BAS/DDC systems accepting 10K thermistor inputs
- Compact sensor head with straightforward field wiring
Applications
- Supply air, return air, and mixed-air duct temperature sensing
- Building automation and direct digital control (DDC) systems
- Energy management and HVAC optimization strategies
- Commercial and light industrial air handling units (AHUs)
Why Choose the KMC Controls STE-1404
KMC Controls has been a trusted name in building automation for decades, engineering sensors and controllers built to perform in demanding commercial environments. The STE-1404’s rigid 12-inch probe ensures consistent contact with the airstream, reducing measurement error caused by stratification near duct walls. The industry-standard 10K thermistor output makes integration with virtually any DDC or BAS platform straightforward, minimizing commissioning time and cost.
Installation Notes
- Mount through a field-drilled hole in the duct wall using the included mounting hardware
- Ensure probe is inserted perpendicular to airflow for optimal accuracy
- Suitable for installation in insulated or uninsulated ductwork
- Refer to KMC Controls installation documentation for wiring and controller configuration details
