1 Scope

The order applies to pressure, vacuum and pressure in the vacuum passive controller (hereinafter referred to as the controller) initial verification, Use and subsequent verification check.

2 Overview

Pressure controller for industrial process measurement and control system for controlling the pressure of a special instrument. Its working principle is When the pressure reaches the set value input to control or alarm. Pressure controller according to the type of pressure-sensing elements can be divided into diaphragm, bellows, bellows, spring and piston tube Type, etc; whether by switching difference adjustable switching difference can be divided into adjustable and non-adjustable switching difference; according to the set point is adjustable to Divided into adjustable set point and the set point is not adjustable.

3 Terms and Definitions

3.1 pressure controller pressureswitch When the input pressure reaches the set value, the output contacts off the role the accused played a pressure control and alarm The role of the instrument. 3.2 pressure control range range The controller can control the pressure range. 3.3 Setpoint (value) setpoint Enter the desired pressure generating control or alarm value. 3.4 switch value switchingvalue When the digital control instrumentation stroke (or the next trip), the output change from one state to another state measured input value. Switching on the value of high-switchingvalue 3.5 When the input pressure rises, the controller generates pressure control or alarm signal upon changes. 3.6 under switch value low-switchingvalue When you enter a pressure drop, the controller generates pressure control or alarm signal upon changes. 3.7 switching difference differentialgap Difference between the value and the lower value of the toggle switch on the same setpoint. 3.8 Setpoint deviation setpointerror Output variable according to the requirements output, the difference between the set value and the measured actual value. 3.9 Setpoint (value) range setpointrange Adjustable set point controller, the setpoint can be adjusted for the difference between the maximum pressure and the minimum pressure value. ......
