FLAMEPROOF PRESSURE SWITCH, HIGH PRESSURE

Explosion‑Proof Switching for Extreme‑Pressure Operations

Durable, Flameproof, and Built for High‑Pressure Safety

When operations demand both high‑pressure handling and explosion protection, the FLAMEPROOF PRESSURE SWITCH, HIGH PRESSURE from AIMS Control delivers unrivaled peace of mind. Its heavy‑duty aluminum pressure die‑cast enclosure is certified Flameproof EEx IIA / IIB / IIC and sealed to IP 65, ensuring that any internal spark stays contained while the unit shrugs off dust, moisture, and corrosive atmospheres.

Explosion‑Proof Design for Hazardous Zones

A precision‑machined AISI 316 SS piston sensing element tolerates severe pressure spikes and pulsations without fatigue. The robust flame‑path design prevents flame propagation, making the switch perfectly suited for Zone 1 and Zone 2 gas or dust environments typical of refineries, chemical plants, and offshore platforms.

Field‑Adjustable Set Point for Precise Control

Technicians can dial in the cut‑in / cut‑out pressure externally via a calibrated screw and scale. Once set, an internal lock secures the setting against vibration or tampering—ideal for unmanned or remote installations. Fixed or adjustable differentials are available to match safety‑shutdown or process‑control requirements.

Process Connection and Electrical Integration

  • Mounting: Bottom process port (¼″ NPT standard) for direct line installation or rear panel bracket for cabinet mounting.
  • Switch Element: 1 × SPDT contact rated 15 A @ 250 VAC / 2 A @ 24 VDC (other ratings on request).
  • Ingress Protection: IP 65 sealing guards internals from wash‑downs and airborne contaminants, extending service life in the harshest climates.

Applications Across High‑Stakes Industries

  • Oil & Gas: Wellhead pressure interlocks, separator and compressor safety cut‑outs.
  • Chemical & Petrochemical: High‑pressure reactor and pump protection in hazardous zones.
  • Power Generation: Boiler and turbine trip circuits requiring flameproof assurance.
  • Hydraulic Equipment: Press brakes, jacking systems, and heavy‑duty actuators operating at elevated pressures.
  • Mining & Marine: Mobile rigs, dredging vessels, and booster‑pump skids exposed to blasting or salt spray.

Accuracy and Compliance

Every switch is calibrated for ± 1 % F.S. repeatability and pressure‑cycled to 150 % of maximum working pressure. Full flameproof documentation, electrical test results, and material traceability for the AISI 316 SS piston accompany each shipment, ensuring compliance with global safety audits.
