Instruments Liquid-Filled Gauges
are designed to perform in rugged applications and harsh
environmental conditions - especially where pulsation and vibration are
a problem. Liquid-filled gauges offer a significant cushioning and
dampening effect, reducing pointer flutter and internal gauge damage;
also lubricating the internals, and reducing corrosion.
All stainless steel
liquid-filled gauges feature a vent top fill plug for pressure relief
and ease of venting after installation. pressure ranges are
available through 20,000 psi, with high pressure ranges offering a
helical bourbon tube for longer gauge life and increased durability.
The hermetically sealed construction reduces the chance of leaks, and
makes field filling an easy option.
