If your application can experience overpressure, your pressure gauge needs to withstand those negative effects. Pressure line spikes and “water hammer” may introduce pressure beyond the operating range of the instrument and cause damage. How can you protect your pressure gauge from the impacts of overpressure? This article will discuss some of the options available for overpressure protection to keep your application running, even in harsh environments.

Protect your pressure gauge from the effects of overpressure with Ashcroft’s new option XRA for the 1209 pressure gauge. This 4 ½-in. stainless steel, solid front pressure gauge now offers option XRA to accommodate up to 417% overpressure without damaging the gauge. In applications where pressure spikes, surges and water hammer are a possibility, option XRA reduces the need for an external pressure limiting valve while extending gauge capacity. The 1209 is also available with optional liquid fill or the patented PLUS!™ Performance option to dampen shock, vibration and pulsation. This review will look at the new option for this pressure gauge and how it can provide reliable pressure measurements for your high-pressure application.
Pressure gauges for 40,000 psi and above are critical for numerous applications where monitoring extremely high system pressures is a required safety precaution. Such gauges must be manufactured so they can withstand the rugged conditions they will be exposed to at these extremely high pressures.
The purpose of a manifold valve is to isolate or block the flow of fluid in the system so the process media may be isolated from pressure instrumentation. A block-and-bleed manifold is used to isolate or block the upstream process media from the instrumentation and allows the bleeding off or venting of the remaining fluid from the system on the downstream side of the manifold.
A steam siphon can be a useful device for protecting your pressure gauges or other instrumentation. The steam siphon is a simple device with the crucial benefit of protecting the instrument from elevated process temperature. However, one of the most common questions I’ve heard during my time working in this industry (and one that our customer service team at Ashcroft hears frequently) is, “Why do I need a steam siphon and how does it work?”
