Coolant Level Sensor XGZP6181

  • Absolute Pressure Type
  • 1bar~11bar(Available to customize range under 50bar)
  • MEMS oil-filling construction
  • Fast response
  • Anti-overload&Shock&Vibration
  • High reliability and stability
  • Low Cost


  • Cooling Systems.
    For data centers, energy storage, battery management and other temperature control systems, this sensor is applied to water-cooled systems to measure coolant pressure to evaluate the system’s heat dissipation function.
  • Air Conditioning Systems.
    Measuring and monitoring the pressure in air conditioning line and feeds this signal back to the ECU, which adjusts the cooling fan speed in time to prevent compressor damage based on this voltage value.



Coolant level sensor XGZP6181 is a finished product of pressure sensor launched by CFSensor for automotive market and industrial control field. The core technology of this product is based on the piezoresistive effect of high temperature resistant MEMS pressure sensor chip and automotive grade signal conditioning AISC chip, which is encapsulated by mature and reliable oil-filled isolation technology, and through the conditioning circuit to calibrate and compensate the sensor signal, the pressure signal is converted to standard analog output signal (range and output can be customized) to ensure the consistency of the output; the product has fast response speed, high reliability and good stability.

Using these sensors products may malfunction due to external interference and surges, therefore, please confirm the performance and quality in actual use. Just in case, please make a safety design on the device (fuse, circuit breaker, such as the installation of protection circuits, multiple devices, etc.), so it would not harm life, body, property, etc even a malfunction occurs. To prevent injuries and accidents, please be sure to observe the following items:

  • The driving current and voltage should be used below the rated value.
  • Please follow the terminal connection diagram for wiring. Especially for the reverse connection of the power supply, it will cause an accident due to circuit damage such as heat, smoke, fire, etc.
  • In order to ensure safety, especially for important uses, please be sure to consider double safety circuit configuration.
  • Do not apply pressure above the maximum applied pressure. In addition, please be careful not to mix foreign matter into the pressure medium. Otherwise, the sensor will be discarded, or the media will blew out and cause an accident.
  • Be careful when fixing the product and connecting the pressure inlet. Otherwise, accidents may occur due to sensor scattering and the blowing out of the media.
  • If the sensor come with sharp PIN, please be careful not to hurt your body when using it.
