Analog to Pressure Transducer

Product Description:

The ACI/PXP converts an analog input signal into a proportional pneumatic output ranging from 0 to 15 psig. The PXP will automatically modulate it's control valve to control the branch line pressure to the selected setpoint as determined by the input signal. Another notable feature of the PXP is that it has an adjustable manual override potentiometer to increase or decrease the pneumatic output and an LED for power indication. An unlit LED shows that their is no power to the ACI/PXP.

All PXP's contain a 0 to 5 VDC feedback signal that can be connected to a controller to monitor the branch line pressure.

The ACI/PXP0.2 is a single valve version that has no restrictor and does not bleed or exhaust air. It depends on its branch line consuming between 14 and 73 scims. The PXP1, 5, and 7 are constant bleed controllers, with branch response times determined by orifice size and pressure differentials.

Both the PXP2.2 and PXP2.2FS incorporate two valves and are not constant bleed controllers. Their branch exhaust flow and response times are similar to its load rate. If power is lost to the PXP0.2, PXP2.2, and PXP2.2FS they will not exhaust any additional air from the branch line where as the PXP1, 5, and 7 will bleed air until the branch pressure is equal to 0 PSI.

The PXP2.2FS is made of (2) Normally Open valves that upon the loss of power will bleed the branch line pressure to 0 PSI.

The input can be either a 0 to 5, 0 to 10, 0 to 15 VDC or a 4 to 20 mA signal.
