Coolant regulator, particularly for coolant circulation of internal combustion engine, comprises multiple sensors, which are designed as wireless temperature sensors for recording temperature values communicating with receiver

摘要

The coolant regulator (5) comprises a thermostatic valve, which has a valve closing member, acted upon by a driving element depending on temperature values. The sensors are designed as wireless temperature sensors for recording the temperature values communicating with a receiver. Multiple sensors are provided, out of those, some are active sensors and the rest are passive sensors. Active sensors are provided, which corresponds to its energy for data communication from its surroundings and passive sensors are provided, which are radio-interrogation surface wave sensors.
