Pressure Sensors When purchasing a pressure sensor for the first time for the project or equipment selection of pressure sensors, often do not know what type is needed, so you need a professional pressure sensor engineers for selection guidance, to provide you with sensing measurement solutions. There are several important parameters you need to understand: Pressure sensor range selection: pressure sensor range should be determined from the product safety considerations, generally choose to make the working pressure value in the standard range value of 60% -80% is appropriate, the entire pressure sensor measurement system may appear in the abnormal conditions caused by the overload pressure shall not exceed the maximum allowable sensor overload. Pressure sensor accuracy selection: the user can be based on the requirements of the test conditions and a single parameter accuracy indicators, in order to achieve higher accuracy requirements with lower prices. Pressure sensor accuracy level should be determined according to the measurement system assigned to the sensor’s large error option selection. Sometimes should also take into account the pressure sensor zero drift, zero and full temperature coefficient of the additional error. Pressure sensor measurement medium: pressure sensor and the measured medium to match the sensor, transmitter enclosure and electronic housing produced by a variety of different materials of construction. With different media compatibility, in order to obtain the use of the effect, not due to media mismatch and damage to the product, the user in the selection of pressure sensors should understand the exact name of the medium, concentration, temperature. Pressure sensor pressure mode: pressure sensors, transmitters, the choice of users according to the nature of the pressure they measure, first of all, should determine the choice of gauge pressure (relative to the local atmospheric pressure), differential pressure, absolute pressure or negative pressure varieties. If the measurement of liquid level, but also to determine the level above the free atmospheric pressure or sealed container pressure. If you measure the level in a sealed pressure vessel, you should use differential pressure products.
