Temperature sensor BHS-HoReCa BHS-K-EVS-DT

A temperature sensor measures the air inside blast chillers and freezers, sending a continuous signal to the control system so the appliance can maintain or change its cooling cycle. In professional kitchens, this sensor is positioned where it samples the coldest and warmest points, allowing the unit to respond before the load drifts outside safe limits. The method relies on a thermistor or resistance element that changes its electrical resistance as the temperature shifts; the control board reads this change and adjusts the compressor, fans and defrost cycles accordingly.

To use the sensor, the operator first ensures the appliance is powered off and disconnected. The old sensor is unclipped or unscrewed from its mounting bracket inside the cabinet. The new BHS-K-EVS-DT is positioned in the same location, reconnected to the wiring harness, and secured. Once power is restored, the control panel will immediately begin reading the new sensor, eliminating the need for manual calibration.

The sensor is housed in a sealed plastic or stainless-steel probe that protects the sensing element from moisture and mechanical damage. Wiring is insulated to withstand the low temperatures and high humidity typical of blast chillers and freezers.

The stated temperature ranges of -5 to +8 °C and -20 to +18 °C correspond to the operating zones of the blast chillers and freezers it is designed for. A sensor rated for -5 to +8 °C is used in units that chill food rapidly to refrigeration temperatures, while the -20 to +18 °C range covers both freezing and defrost cycles. The 1 1/2 to 4 1/2 section notation indicates the number of standard gastronorm trays the appliance can hold, helping to match the sensor to the correct model.

Cleaning is limited to wiping the probe with a damp cloth; no water should enter the connector or wiring. Regular inspection of the mounting bracket ensures the sensor remains correctly positioned for accurate readings.

This sensor fits BHS blast chillers and freezers in the specified section ranges, replacing the original part without modification.

In the BHS catalogue, the BHS-K-EVS-DT is listed under spare parts for refrigeration equipment.
