The upper range of the pressure transmitter should be higher than the maximum possible pressure value in the actual operating condition. Proper range selection can extend the service life of the pressure transmitter: According to our years of experience in automatic control design, When measuring the steady pressure: the maximum working pressure should not exceed 2/3 of the upper limit of the measurement, When measuring pulsating pressure: the maximum working pressure should not exceed 1/2 of the upper limit of measurement, When measuring high-pressure pressure: The maximum working pressure should not exceed 3/5 of the upper limit of measurement. After calculating the upper limit of the instrument according to the maximum value of the pressure under the working condition, it is not possible to use this value directly as the measurement range of the pressure transmitter. Because the range of the pressure transmitter is not arbitrary, it is necessary to select the nearest range column reasonably according to the selection parameters provided by the star sensor. Star Meter Manufacturing Co., Ltd. is a high-tech enterprise integrating R&D, production and sales. Specializing in the production of pressure transmitters, liquid level transmitters, temperature transmitters, temperature and humidity transmitters, differential pressure transmitters, soil moisture transmitters, 3051 transmitters and related instrumentation accessories.
