Freezing point is determined independently from the de-icing material

Active cooling concept enables the freezing point determination independently from de-icing material.

Maintenance, calibration and replaceability

Sensor consists of two parts: replaceable sensor head with electronics and fixed mounted socket.

Extra road surface temperature sensor

Actual surface temperature sensor is integrated into a second housing for accurate measurements not influenced by the active colling/heating element. One additional measurement is carried out to find out critical conditions in the next few hours.

Invasive technology allows

Permanent usage on runways where non-invasive sensors cannot be used.
