Baratron® 41C Single-End Gauge Pressure Switches
Overview
The 41C Single-end 10 - 26,000 Torr 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 41C is referenced to atmospheric pressure. The trip point on can be set to trip above, below (reverse calibration), or exactly at current atmospheric pressure.
- Single-end configuration referenced to atmospheric pressure
- Superb set point accuracy with low hysteresis
- All-metal, all-welded construction exposes 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
