Rs 485 pressure sensor digital RS485 output transmitter

Product description How to detect high precision pressure sensors? The detection of the bridge is mainly to detect the circuit of the high precision pressure sensor, generally the whole bridge circuit is detected. The ohm of a multimeter is used to measure input and output impedance. These two impedances are respectively input impedances and output impedances of high precision pressure sensors. If the impedance is infinite, the bridge panel breaks, indicating a problem with the high precision pressure sensor or an incorrect pin definition. Zero-point detection, using the voltage level of a multimeter to detect the zero-point output of a high-precision pressure sensor under the condition of no voltage. The output voltage is generally millivolts. If it exceeds the technical index of the high precision pressure sensor, it means that the zero deviation of the high precision pressure sensor is out of the measuring range.
