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. The hermetically sealed construction reduces the chance of leaks, and makes field filling an easy option. |
