Pressure controllers for flowing processes

Open in new window

Single-valve pressure controllers from Alicat are designed to rapidly control the pressure of flowing processes. They are available with internal pressure sensors or remote sensors that can be plumbed to any point in your process.

Absolute or gauge pressure

PC-series absolute or gauge pressure controllers contain pressure sensors that are referenced to vacuum (absolute) or to local barometric pressure (gauge). PC3-series absolute or gauge pressure controllers have flow paths that are isolated from their pressure sensors. Instead, an external pressure sense port can be plumbed to measure pressure at any point in your system.

The EPC series condenses our single-valve PC series absolute or gauge pressure controller into a bare-bones form factor that is ideal for OEM applications and large-quantity orders.

Differential pressure

PC-series differential pressure controllers maintain a constant pressure differential between their two measurement ports. Like the PC3 above, each of the two pressure measurement ports of the differential pressure controller can be plumbed to any point in your process.

Faster Leak Testing (PC3)

Establish stable pressure for the leak check by measuring pressure precisely at the device under test with Alicat’s PC3-series pressure controller with remote sense port.

 

Filter Characterization with Differential Pressure Control (PC)

Characterize the flow vs. pressure drop curve by fixing the differential pressure across the filter using a differential pressure controller.

 

Vacuum Coating with Pressure Control (PC-EXTSEN)

Use your favorite vacuum gauge with Alicat’s PC-EXTSEN pressure controller to maintain the ideal absolute pressure for vacuum deposition.

 

Split Flow Gas Chromatographs (EPC)

Small size, fast response and dual analog/digital communications make the EPC easy to build into OEM products.

Pressure controllers for closed volumes

Open in new window

Dual-valve pressure controllers from Alicat eliminate the need for a bleed valve for pressure control in closed or dead-ended volumes. They are available with internal pressure sensors or remote sensors that can be plumbed to any point in your process.

Absolute or gauge pressure

PCD-series absolute or gauge pressure controllers contain pressure sensors that are referenced to vacuum (absolute) or to local barometric pressure (gauge). In addition to inlet and outlet ports, a third process port connects the sensor to your closed volume. PCD3-series absolute or gauge pressure controllers have flow paths that are isolated from their pressure sensors. In addition to the process port, an external pressure sense port can be plumbed to measure pressure directly from any point in your closed system.

The EPCD series compacts our dual-valve PCD series absolute or gauge pressure controller into a bare-bones form factor that is ideal for OEM applications and large-quantity orders.

Differential pressure

PCD-series differential pressure controllers maintain a constant pressure differential between their two measurement ports. Like the PCD3 above, each of the two pressure measurement ports of the differential pressure controller can be plumbed to any point in your process.

Fluid Dispensing Using Pressure Control (PCD)

Control the pressure in the head space above the liquid to be dispensed with minimal waste of process gases.

 

Electronic Pressure Control with Remote Sensing (PCD3)

Accurately monitor and control the pressure in a closed volume, even when flow rates are high.

 

Valve Characterization in Martian Environments (PCD)

Cycle through several pressure differentials that are referenced to the simulated Martian atmosphere instead of Earth’s own atmospheric pressure.

 

Fluidic Dispensing for Flow Cytometry (EPCD)

High accuracy and wide usable ranges make possible the dispensing of precise amounts of fluid with your OEM instrument.

Differential pressure controllers and transducers

Open in new window

Differential pressure instruments from Alicat have sensors that measure the difference in pressure between any two points in your process. If you leave the downstream port open to atmosphere, the differential pressure readings become equivalent to gauge pressure readings, allowing differential pressure instruments to work as gauge pressure instruments as well.

P-series differential pressure transducers display the pressure difference between your two measurement points.  The PB-series differential pressure transducers add a rechargeable battery to make pressure audits easy.

PC-series differential pressure controllers use a single valve to maintain a constant pressure differential between their two measurement ports. Their flow paths are isolated from the two ports of the differential pressure sensor. Each of these two pressure measurement ports can be plumbed to any point in your process.

PCD-series differential pressure controllers use two valves to control pressure differentials for closed volumes. The second valve opens only to vent excess pressure from the system. Like the PC series above, each of the two pressure measurement ports of the PCD for differential pressure is isolated from the flow path and can be plumbed anywhere in your system.

Filter Characterization with Differential Pressure Control (PC)

Characterize a filter’s flow versus pressure drop curve by fixing the differential pressure across the filter.

 

Valve Characterization in Martian Environments (PCD)

Cycle through several pressure differentials that are all referenced to the simulated Martian atmosphere instead of Earth’s own atmospheric pressure.

Pressure transducers

Open in new window

Digital pressure transducers from Alicat provide real-time measurements of absolute, gauge or differential pressure.

Absolute or gauge pressure

P-series absolute or gauge pressure transducers reference pressure to vacuum (absolute) or to local barometric pressure (gauge). PB-series absolute or gauge pressure transducers add a rechargeable battery to make your pressure transducer easily portable.

Differential pressure

P-series differential pressure transducers display the pressure difference between the two measurement points. If you leave the downstream port open to atmosphere, the differential pressure readings become equivalent to gauge pressure readings. The PB-series differential pressure transducers feature an integrated rechargeable battery.
