EPC Single Valve Controller

Alicat Scientific EPC-Series Pressure Controllers incorporate a digital pressure

gauge with a single control valve and circuitry. The integrated control

algorithm measures the pressure, compares it with the setpoint, and adjusts

the valve accordingly at 1000 times per second.

The response time of the system will depend on the operating conditions and

the PID tuning of the device.

EPC-Series Pressure Controllers are normally intended to control the process

pressure downstream of the controller. In order for this to occur, a supply

pressure greater than the full scale pressure control range of the device

should be connected to the "IN" port.

EPC-Series Pressure Controllers can also be configured as back pressure

controllers, opening to release pressure upstream of the controller, and

closing to increase restriction and increase pressure upstream of the

controller. EPC Back Pressure controllers will have a "DS" in the part number.

EPCD Dual Valve Controller

Alicat Scientific EPCD-Series Closed Volume Pressure Controllers incorporate

a digital pressure gauge with dual control valves and circuitry. The integrated

PID loop measures the pressure, compares it with the setpoint, and adjusts

either the Inlet or Exhaust valve accordingly at 1000 times per second.

They are designed with a feed port, a process port, and an exhaust port. This

allows the controllers to raise and lower the pressure of a closed system

within the operating range of the controller without wasting gas under

constant pressure conditions.



Connect your EPCD into your process via the "OUT" port of the

unit. This is the "Process" port.



Connect a supply pressure greater than the full scale pressure

control range of the device to the "IN" port.



The "VENT" port can vent to atmosphere or be tied to a vacuum

source as the application demands.

✓

Note: The pressure at the vent port should be at atmospheric pressure or

below to allow the controller to be used over its full scale range.
