51C Baratron® Single-ended Absolute Pressure Switches
Overview
The 51C Single-end Pressure Switch offers accurate and reliable protection for vacuum vacuum/pressure processes. Designed for applications where a DC signal output is not required, these switches provide relay outputs that are readily interfaced with alarms, valve actuators, computers, process controllers, load locks and other protection devices. The 51C is referenced to vacuum.
- Single-end configuration referenced to vacuum
- Superb set point accuracy with low hysteresis
- All-metal, all-welded construction exposing only stainless steel and Inconel® for corrosion resistance
- Switch relay can be set to energize above or below set point for fail-safe operation
- High reliability reduces downtime
