Instrumentation, Equipment & Calibration Services

PGI INTERCEPTOR SAMPLERS – PGI is a premier manufacturer of composite sampling systems for gas and refined liquid applications offering the most cost effective systems by means of patented technological advancements.

PGI DIRECT-MOUNT SYSTEMS – PGI is the recognized industry leader in the close coupling of manifold systems. Pioneered by PGI in 1988, Direct-Mount™ Systems can minimize or eliminate Gauge Line Error (GLE), resulting in more accurate flow measurement

PGI offers a wide range of manifolds to fit any service, meet any requirement, all with the patented Teflon® Pressure-Core® Stem Seal with an unmatched 5 year warranty. Our offering of 2,3 and 5 valve manifolds ranges from a simple by-pass manifold to our sophisticated purge adapter. All are available in a wide range of material. All of our 316 stainless steel manifolds meet NACE MR0175/ISO 15156-3 as standard.

Turn-Saver™ — Only 3-1/2 Turns!
This new innovative feature minimizes the number of turns to fully open or close the bonnet of the valve or manifold assembly. The Turn-Saver allows less repetitive motion and saves significant time during calibrations or transmitter replacement. This added feature comes without an added price on all PGI Pressure-Core large bore soft seat applications.

PGI’s Valves Systems feature the patented Teflon® Pressure-Core® Stem Seal with an unmatched 5 year warranty. All valves and manifolds are available with a bonnet handle lock-out that prevents unauthorized cycling in either the open or closed position, or an anti-tamper bonnet that allows the bonnet stem to be placed in any position before removing the handle. OS & Y bonnets available. Standard 316 SS models conform to NACE MR0175/ISO 15156-3.

What is a Rosemount Transmitter?

In industrial process control, a “transmitter” is any device which converts measurements from a sensor into a signal, conditions it, to be received, usually sent via wires, by some display or control device located a distance away. Typically in process control applications the “transmitter” will output an analog 4-20 mA current loop or digital protocol to represent a measured variable within a range. For example, a pressure transmitter might use 4 mA as a representation for 50 psig of pressure and 20 mA as 1000 psig of pressure and any value in between proportionately ranged between 50 and 1000 psig. (A 0-4 mA signal indicates a system error.) Older technology transmitters used pneumatic pressure typically ranged between 3 to 15 psig (20 to 100 kPa) to represent a process variable.
