## Summary description

Hewalex KS 3m temperature sensor is an external temperature probe supplied with a 3-meter cable for remote measurement. Designed to measure ambient or outdoor temperature, it connects to compatible Hewalex controllers and monitoring devices. Suitable for weather stations, HVAC systems, and solar installations where a compact external probe and fixed cable length are required.

## Long description

The Hewalex KS 3m temperature sensor is an external probe with a fixed 3-meter cable designed for remote measurement of ambient and outdoor temperature. It is compatible with Hewalex controllers and monitoring devices that accept external temperature probes. The compact probe housing provides straightforward installation on façades, panels or near HVAC and solar equipment where an accurate external temperature reading is required.
Advantages
The external probe design separates the sensing element from the controller, allowing measurement at a distance while keeping the main device protected. The fixed 3 m cable simplifies installation without the need to purchase additional wiring, and the compact, weather-resistant housing facilitates placement in exposed locations. Compatibility with Hewalex systems ensures direct integration into existing controllers and monitoring setups that support external temperature inputs.
Suitable for
 Outdoor ambient temperature monitoring for weather stations
 Temperature sensing for HVAC systems and duct or facade mounting
 Temperature input for solar thermal controllers and monitoring
 Remote temperature measurement where a small, fixed-length probe cable is required
Key specifications
 Sensor type: external temperature probe for ambient/outdoor measurement
 Cable length: 3 meters (fixed)
 Housing: compact, suitable for external mounting (weather-resistant)
 Compatibility: designed for use with Hewalex controllers and monitoring devices supporting external probes
 Typical mounting: façade, panel, near HVAC or solar equipment
How to use
Install the probe at the desired outdoor or ambient location, avoiding direct sunlight and sources of heat that could bias readings. Route the 3 m cable to the Hewalex controller or monitoring device and connect according to the controller's external probe input instructions. Secure the probe housing to a stable surface using suitable fasteners or clips so that the sensor element is exposed to ambient air for accurate measurement. After connection, verify readings on the controller display and allow a short stabilization period for the sensor to reach ambient temperature.
Usage recommendations
For reliable measurements, mount the probe in a shaded, well-ventilated position and away from radiative heat sources. If longer cable runs are required, plan location accordingly since the unit is supplied with a fixed 3 m cable. Regularly inspect the cable and housing for physical damage and clean the probe housing gently if debris accumulates.
