Constant Pressure Control Solution Case V0.1 For Water Pump And Fan - HNC Electric HV610 Series User Manual

Constant pressure control solution Case V0.1 for water pump and fan

1.1. Overview
The process PID closed-loop control regulates the rotation speed of the motor and indirectly controls the water
pressure or air pressure of the pipeline to be constant.
2.1 Two types of pressure sensors for pump and fan control
Type 1: 0 ~ 10v remote pressure gauge
Type 2: 4 ~ 20ma pressure transmitter
3.1 Control wiring diagram
Type 1: pressure sensor is 0 ~ 10v remote pressure gauge
Type 2: the pressure sensor is a 4 ~ 20mA
Pressure transmitter
