SM25K07 The liquid level pressure sensor (transmitter) is made of diffused silicon material by special process and laser correction. It contains high-performance signal conditioning circuit and unique sealing process, which can be stably used underwater and other liquids for a long time. It not only has the functions of automatic zero point correction and full scale linear adjustment, but also has active nonlinear correction and frequency response shaping technology to ensure that the sensor transmitter has high measurement accuracy. The hollow cable is used to transmit signals, which counteracts the influence of atmospheric pressure changes on measurement accuracy. It is especially suitable for petroleum, chemical industry, water conservancy and hydropower, urban water supply, hydrological exploration, metallurgical mines and other fields.
