This document is an introduction manual for Schneider Electric's pressure switch products. It provides detailed information on the features and characteristics of each of Schneider Electric's pressure switch products.
This document introduces Barksdale’s pressure switch products, covering types like diaphragm, bourdon tube, and piston switches. It provides selection criteria based on service life, proof pressure, function, housing, and adjustable range. Application guidelines include wiring diagrams for various control scenarios and considerations for steam, chemical, and corrosive environments.
The guide also addresses life expectancy factors, such as flexing range and cycling speed, and offers recommendations for specific environments like steam service or corrosive conditions, with notes on compatible fittings and chemical protectors.
| Adjustable Range | Vacuum to 150 psi for diaphragm switches |
|---|---|
| Maximum Proof Pressure | 24,000 psi for bourdon tube switches |
For service life of one million cycles or less, use bourdon or diaphragm switches. For more than one million cycles, use piston switches.
For optimal accuracy and life, the set point should be in the middle 30% of the adjustable range.
