The relation between the voltage signal collected by the pressure sensor and the measured pressure value
When the pressure changed from P0 to PMAX, the linear pressure sensor, its output is from V0 to VMAX, if the output of the VX sensor, can be obtained from the PX type under pressure:PX=P0+ (VXV0) * (PMAXP0) / (VMAX-V0)The factory should be calibrated the sensor, is given a known P0, PMAX, V0, VMAX measured values can be obtained on the slope type; then the output of the sensor VX know as long as we can find the pressure value of PX.Turn left and turn right |
We use the pressure transmitter here, the output is the standard 4 ~ 20mA signal, 4mA corresponding to zero pressure, 20mA corresponding to the upper limit of measurement of transmitter (Ji Liangcheng), the middle is linear correspondence. Are generally current signals, there are voltage signals, generally 0 ~ 10V. The corresponding relation is identical to that of the current signal.
