High-purity applications require a particular type ofpressure gaugeto ensure accuracy, safety and repeatability. The materials from which it’s made and its safety features must be specialized for demanding environments.
Do you have the right high-purity pressure gauge for your process? Do you need enough space to have multiple devices measuring your process?
Ashcroft’s newly releasedHPS high-purity pressure gauge with reed switchmight be right for you. This article will describe the features of this new gauge and how it can help keep your application, and business, running.
Important Features
The Ashcroft 50 mm HPS high-purity pressure gauges with reed switch are ultrasonically cleaned to provide exceptional quality and reliability in ultra-high-purity gas delivery systems. Its stainless-steel construction and wetted components are ideal for use with industrial gases in semiconductor and electronic manufacturing.
The reed switch capability provides an additional safety feature by actuating an internal switch that triggers an alarm or a process condition change. Thishigh-purity pressure gaugeis an ideal choice for reducing installation costs and providing an added space reduction benefit.
It also has a number of other features that make this gauge stand out:
- 316L Stainless steel wetted parts
- Helium leak tested to 1 x 10-8scc/s
- Cleaned in class 10,000 cleanroom
- Packed in a Polyethylene-sealed bag after nitrogen gas flushing
Materials
This gauge case is made from 304 stainless steel and the bourdon tube/process connection is 316L stainless steel.
