description Technical Overview
Zedeyes 212 Electric Contact Pressure Gauge
The Zedeyes 212 is an economical, industrial-grade electric contact pressure gauge designed for combined pressure monitoring and automatic process switching. Engineered with a durable stainless steel safety case (Version S1 per EN 837) and precision brass movement, it offers a reliable solution for opening or closing electrical circuits based on real-time process pressure levels.
When system pressure reaches or exceeds a pre-configured set-point, the gauge pointer engages the contact arm to either close a circuit (Normally Open / NO) or interrupt a circuit (Normally Closed / NC). This dual-functionality eliminates the need for separate pressure switches and dial gauges, streamlining control panel installation and reducing equipment costs.
Key Features & Benefits
-
Dual Monitoring & Control: Combines local pressure indication with reliable electrical switching in a single instrument.
-
Economical & Durable Design: Features a robust 304 stainless steel case combined with a high-precision brass movement and copper alloy pressure element.
-
Snap-Action Contacts (EC1): Equipped with 70% silver / 30% nickel gold-plated contacts to ensure arc resistance, high conductivity, and long switching service life.
-
Safety Version S1 (EN 837-1): Includes a heavy-duty safety glass window and protective case design engineered according to strict European standard safety guidelines.
-
Versatile Switching Modes: Supports both normally-open (NO) and normally-closed (NC) switching logic to adapt to diversas safety shutdown and system control routines.
-
Flexible Sizing & Pressure Ranges: Available in standard 100 mm and 160 mm nominal dial sizes across extensive measuring spans from 0–1 bar up to 0–600 bar, including compound and vacuum ranges.
Primary Applications
-
Industrial Process Automation: Automatic pump control, motor start/stop triggers, and valve actuation.
-
Alarm & Safety Shutdown Systems: Immediate over-pressure or loss-of-pressure limit switching in utility circuits.
-
Hydraulic & Pneumatic Power Units: Pressure level maintenance and automatic pressure relief control.
-
General Industrial Machinery: Cost-effective pressure monitoring for OEM equipment and factory test benches.
