Differential Pressure Sensors vs. Pressure Gauges by Definition: Differential Pressure Sensors The primary function of a differential pressure sensor is to transmit a pressure signal to an electronic device, which in turn displays the pressure in a computer. A pressure gauge is an instrument that measures and indicates pressure above the ambient pressure using an elastic element as the sensitive element. The difference between pressure sensors and pressure gauges in terms of power supply: Pressure sensors need a separate power supply, on-site or remote transmission can be displayed, but also can output signals. Pressure gauge does not need power supply, only on-site digital. Can only display the value of pressure. Pressure sensor and pressure gauge in the display of the difference: Pressure sensor is the sensing part, need to connect a display table, send out 4-20 mA current signal, by the display table converted to pressure values. Pressure gauge is in situ table, direct reading. The sensing part and the display part are together. Pressure sensor and pressure gauge in the accuracy of the difference: Pressure sensors can be remotely monitored, with anti-interference, overload and shock resistance, small temperature drift, high stability, high measurement accuracy, is the ideal pressure measurement instrument in the field of industrial automation. Low accuracy of pressure gauge. Pressure sensors and pressure gauges in the connection of the difference: Pressure sensors need to be wired to connect to the back-end acquisition equipment. Pressure gauge can be directly threaded connection, you can visualize the current pressure.
