Description
Applications
- Test, laboratory, and production applications
Special Features
- Capsule-type pressure elements
- High differential pressure is applied to the capsule; low pressure to the case
- Available in 22 standard ranges, they combine aneroid convenience with liquid-column accuracy
- Rugged enough to maintain their high accuracy in test and process applications
