Focus on pressure

Pressure is a measure of applied force compared with the area over which the force is exerted. Key terms: Pressure control is managed by a device or system that can raise, lower, or maintain the internal pressure in a vessel or in process equipment; pressure measurement determines the internal force per unit area in a process vessel, tank, or piping system as a result of fluid or compressed gas; and pressure rating is the maximum allowable internal force pre unit area of a pressure vessel, tank, or piping system during normal operation.

Transducers

The PX5500 Transducer Series provides high performance in demanding industrial and research applications where accuracy, reliability, and price are important. This transducer has a 10-year MTBF rate and is stable to 0.1% of FSO over an 18 month period. This translates into less down time, fewer test reruns, more time between calibrations, and high confidence in your pressure data. When recalibration is impossible, relying on the high stability of the PX5500 Series transducer may be the only cost-effective way to obtain pressure data over the long term. 

The thin film technology makes this premium performance possible. The strain gages and associated structures are sputter-deposited directly onto the pressure sensing element thus eliminating the need for adhesives. The resulting molecular bond between the sensing element and the strain gages ensures virtually no shifting, drifting, or "creep" in the performance of the transducer. The micro-geometry design of the PX5500 sensing element results in a very small, low mass sensor that reduces effects of mechanical vibration and shock.

Gauges

The Cecomp F16-series programmable pressure/vacuum gauges offer high accuracy and ruggedness at a competitive price. The gauges can be customized with the features you need for your application. They are available in most engineering units with pressures to 5000 psi plus vacuum, bipolar, absolute, and compound (inHg/psig) ranges. 

Models that operate on battery or low voltage AC/DC power offer min/max capture and pushbutton zero. 2-wire loop-powered versions and 4-wire transmitters are available. Models with user-settable alarm relays and/or analog output provide maximum versatility. An optional NEMA 4X housing makes the F16 series ideal for industrial applications.  

Accuracy is ±0.25% with 316 stainless steel wetted parts and a ¼" NPT process connection.

Regulator

The Type 3500 High Pressure Regulator reduces inlet pressures from as high as 6000 psig (413 BAR) down to working pressures ranging between 0 and 225 psig (15.5. BAR). The self-operated, high-pressure regulator can be designed to be used in applications requiring high-pressure reducing regulators for various gases. The Type 3500 regulator can also be used where high-pressure gas must be reduced for use as pilot supply pressure in pilot-operated regulators or as loading pressure in pressure-loaded regulators.

The Type 3500 regulator provides outlet pressure to 225 psig (15.5 bar) in three spring ranges: 0-125 psig (0-8.6 BAR), 0-150 psig (0-10.3 BAR) and 0-225 psig (0-15.5 BAR). A choice of three output ports provides plumbing flexibility for easy hookup. A replaceable nylon valve seat provides up to 4 replacement sealing surfaces. The Type 3500 regulator is optionally available with a ¼" NPT female connection on the spring case for remote venting (tapped exhaust).  Socket head or tee handle adjustment is available.
