## Summary description

The DEVI 140F1091 is a high-quality floor sensor designed for precise temperature monitoring in electric heating systems. Featuring a resistance of 15 kOhm at 25°C and a 3-meter cable length, this sensor ensures reliable feedback for thermostat control. It is an essential component for maintaining optimal comfort and energy efficiency in underfloor heating installations.

## Long description

The DEVI 140F1091 floor sensor is a precision-engineered component designed to provide accurate temperature feedback for electric underfloor heating systems. By monitoring the floor surface temperature, this sensor ensures that your heating system operates efficiently and maintains the desired comfort levels within your living space. It is built to be durable and reliable, serving as a critical link between the floor structure and the thermostat controller.
Advantages
This floor sensor offers high accuracy in temperature detection, which is vital for the effective regulation of electric heating elements. Its robust construction ensures long-term stability, reducing the need for maintenance or replacement. The 3-meter cable provides sufficient length for most standard installations, allowing for flexible positioning of the sensor tip within the floor construction to achieve optimal thermal readings.
Suitable for
Electric underfloor heating systems
Residential and commercial floor temperature monitoring
Integration with compatible DEVI thermostats
This sensor may not be suitable for use with heating systems that require a different resistance value or for applications involving extreme industrial temperatures outside the standard range for residential floor heating. It is also not intended for use in environments where the cable might be exposed to harsh chemicals or mechanical stress that exceeds its design specifications.
Key specifications
Resistance: 15 kOhm at 25°C
Cable length: 3 meters
Application: Floor temperature sensing
Compatibility: Electric heating thermostats
To install the sensor, it should be placed inside a flexible conduit within the floor structure. This allows the sensor to be easily inserted or removed if necessary. The tip of the sensor should be positioned between two heating cables, ensuring it is not in direct contact with the heating element itself to prevent false temperature readings. Once positioned, the sensor wires are connected to the designated terminals on the thermostat.
What to consider before purchase
Verify that your thermostat is compatible with a 15 kOhm sensor
Ensure the 3-meter cable length is sufficient for your installation layout
Confirm the sensor is intended for floor temperature monitoring rather than ambient air sensing
Usage recommendations: Always install the sensor within a conduit to protect it from concrete or tile adhesive and to facilitate future maintenance. Ensure the sensor tip is placed at an equal distance between heating cables for the most accurate temperature measurement.
