3 Terms
The following terms and definitions apply to this standard.
3.1
Pressure controller pressurecontroler
To control or alarm when the measured pressure reaches the set point, but the device does not indicate the measured pressure function.
3.2
Control voltage range controlablepressurerange
The controller can control the pressure range.
3.3
Setpoint (value) setpoint
I want to happen input pressure switch.
3.4
Switch value switchingvalue
The output signal of the controller changes the pressure value.
3.5
The switch value upperswitchingvalue
When the input pressure rises, the controller output signal of the pressure changes when the value.
3.6
By switching value lowerswitchingvalue
When the input pressure drop, the pressure controller output signal changes when the value.
3.7
Reset value resetvalue
With the rise in input pressure, the output signal of the controller changes (ie, the switch), and then enter the pressure drops, the controller signal
