FLAMEPROOF DIFFERENTIAL PRESSURE SWITCH

FLAMEPROOF DIFFERENTIAL PRESSURE SWITCH

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

Overview

The FLAMEPROOF DIFFERENTIAL PRESSURE SWITCH from AIMS Control safeguards filtration, flow, and pump systems operating in explosive atmospheres. Encased in a heavy‑duty aluminum pressure die‑cast housing that is flameproof to EEx IIA / IIB / IIC and sealed to IP 65, it prevents internal ignition sources from reaching the surrounding environment. Field engineers can fine‑tune the set‑point externally, then secure it with an internal lock ring—achieving both flexibility and tamper‑proof safety.

Key Features & Benefits

• Flameproof Safety (EEx d IIA / IIB / IIC)

Certified for Zone 1 & 2 gas groups, stopping flame propagation during internal arcing events.

• Field‑Adjustable Set Point

Graduated external scale plus screwdriver slot allow rapid calibration; internal set‑point lock prevents drift.

• Fix / Adjustable Differential

Choose a factory‑fixed dead‑band for critical cut‑outs or an adjustable differential for process optimisation.

• High Repeatability

AISI 316 SS diaphragm and snap‑action contacts deliver ± 0.5 % F.S. repeatability for accurate switching.

• Heavy‑Duty Contacts

1 × SPDT rated 15 A @ 250 VAC / 2 A @ 24 VDC handles motors, solenoids, or PLC inputs with ease.

• Ingress Protection IP 65

Gasketed joints keep dust and water out—ideal for wash‑down areas and humid environments.

• Versatile Mounting

Bottom process port for inline installation or rear bracket for panel mounting.

Why Choose This Switch?

1. Explosion‑Proof Assurance – Protects personnel and equipment in Zone 1 & 2 hazardous areas.
2. Precision Differential Control – Ensures stable trip points for filter monitoring, pump protection, and flow safety.
3. Tamper‑Proof Calibration – Internal lock ring secures settings in high‑vibration and remote locations.
4. Backed by pressure gauge manufactures in Gujrat India – Local stock, quick lead times, and expert technical support.
