## Summary description

DANFOSS temperature sensor model 140F1091 with a 15 kOhm resistance value in a black finish. Designed for temperature measurement and control in heating systems and related appliances, it provides a fixed resistance characteristic for use with compatible controllers and thermostats. Suitable for replacement or integration into residential and light-commercial setups.

## Long description

The DANFOSS 140F1091 temperature sensor is a fixed-resistance sensing component with a nominal resistance of 15 kOhm in a black housing. It is intended for temperature measurement and control within heating systems and associated appliances where a passive, stable resistance element is required by compatible controllers, thermostats or control modules. The sensor is supplied as a replacement or for integration into residential and light-commercial heating installations and accessory assemblies.
Advantages
This sensor provides a consistent 15 kOhm resistance characteristic suitable for systems designed to accept fixed-resistance temperature inputs. The compact black housing allows discreet installation in a variety of locations and integrates with standard control wiring. As a component from DANFOSS, the unit is produced to align with common application requirements in heating control circuits, enabling straightforward replacement or upgrade without redesign of the control logic.
Suitable for
Temperature sensing in residential boilers and central heating controllers
Replacement of compatible thermostat probes and sensor modules
Integration into light-commercial HVAC equipment requiring a 15 kOhm passive sensor
Use in control cabinets or accessory panels where a fixed-resistance input is needed
Key specifications
Sensor type: fixed-resistance temperature sensor
Nominal resistance: 15 kOhm
Finish: black housing
Application area: heating systems, thermostats, controllers
How to use
Install the DANFOSS 140F1091 sensor by connecting it to the compatible input terminals of the controller or thermostat configured to accept a 15 kOhm passive temperature sensor. Ensure the electrical connections are secure and that wiring conforms to the equipment manufacturer’s polarity and terminal specifications. Position the sensor in the location representative of the medium or ambient temperature to be measured, avoiding direct exposure to heat sources or drafts that could skew readings. After installation, verify that the controller recognizes the sensor input and that temperature readings are stable before returning the system to normal operation.
Usage recommendations
Use the sensor as a direct replacement only where the control system specifies a 15 kOhm passive input. Follow the heating system and controller documentation for wiring, mounting and environmental limits. If uncertain about compatibility, consult the controller manufacturer or a qualified technician to confirm correct sensor selection and to ensure safe installation.
