There are a variety of options and accessories for pressure gauges and pressure transducer/transmitters that are designed to address specific application requirements, and ensure safe operation and installment.
Liquid filling in a pressure gauge reduces the effects of mechanical vibration and pressure pulsation, and can dampen pressure spikes during operation making the gauge pointer easier to read.
Piston snubbers protect a gauge, transducer, or transmitter from pressure pulsation and pressure spikes. This type of snubber resists clogging and is self-cleaning.
Sintered snubbers are another cost effective solution to protect expensive instrumentation. Sintered snubbers increase gauge readability by smoothing out pressure surges, pulsations and spikes. Multiple elements can be chosen for each snubber to accommodate specific application needs such as gases, water, light oil and heavy oil.
Steam syphons protect the gauge, transducer, or transmitter from the damaging effects of high temperature steam, and are recommended for use in all steam applications.
Diaphragm seals are designed to isolate and/or protect pressure gauges, pressure transducers and pressure transmitters from corrosive, viscous, contaminated or very high temperature process media. See the article above for more detailed information on seals.
Needle valves can provide block and bleed function for a pressure sensor in the system. Good industry practices state that a pressure measurement device should be “blocked in or have a block and bleed feature” for safety and ability to service the instrument.
