FLAMEPROOF PRESSURE SWITCH

FLAMEPROOF PRESSURE SWITCH

EEx IIA / IIB / IIC‑Certified Switch for Hazardous Gas & Dust Zones

Overview

The FLAMEPROOF PRESSURE SWITCH from AIMS Control is designed to provide uncompromising safety and precision in explosive atmospheres such as refineries, paint booths, and LNG terminals. Encased in a heavy‑duty aluminum pressure die‑cast housing certified flameproof to EEx IIA, IIB, IIC and sealed to IP 65, this switch isolates ignition sources while maintaining exact, repeatable pressure control. Field technicians can fine‑tune the set‑point from outside the enclosure, then lock it internally to prevent tampering or vibration drift.

Key Features & Benefits

• Flameproof Enclosure (EEx IIA / IIB / IIC)

Meets global standards for Zone 1 & Zone 2 gas groups, preventing flame propagation in case of internal arcing.

• Field‑Adjustable Set Point

External screw with graduated scale enables rapid calibration; internal lock ring secures final value.

• Fix / Adjustable Differential

Order with factory‑fixed dead‑band for safety circuits or adjustable differential for process flexibility.

• High Repeatability

Snap‑action mechanism and AISI 316 SS diaphragm deliver ± 0.5 % F.S. repeatability.

• Heavy‑Duty Contacts

1 × SPDT rated 15 A @ 250 VAC / 2 A @ 24 VDC handles direct motor loads or low‑level PLC inputs (other ratings on request).

• Ingress Protection IP 65

Gasketed joints and cable glands keep dust and water out—even in wash‑down areas.

• Versatile Mounting

Bottom process port for in‑line installation; optional rear bracket for panel integration.

Why Choose This Switch?

1. Certified Explosion Safety – Protects people and assets in Zone 1 & 2 hazardous areas.
