Page 6: 2．Function
2．Function The pressure sensor of this product can measure differential pressures. If the pressure on the H side is higher than that of the L side, the pressure display shows a positive value. This sensor performs A/D conversion of the signal from the pressure sensor, then performs zero compensation and movement average processing, and finally displays the value and performs the digital communication output. -
Page 7: Digital Communication Function (Modbus)
2-2 Digital communication function (MODBUS) 1）Digital communication (input/output) By means of RS-485 (MODBUS/RTU) communication, it is possible to acquire pressure measurement values, execute zero adjustment, and change the various settings. For the items and effective value ranges, refer to P.18 “4-5 MODBUS address map“. 2）Output filter The number of the moving average filter for digital communication output is set in the output filter setting mode. -
