MINIATURE DIAPHRAGM SEAL

MINIATURE DIAPHRAGM SEAL

Compact, Economical & Weld‑Tight Protection for Small‑Dial Gauges

When space is limited but media compatibility and measurement accuracy are critical, the MINIATURE DIAPHRAGM SEAL from AIMS Control offers full‑scale protection in a pocket‑size form factor. Engineered for 50 mm and 63 mm pressure gauges, this all‑stainless, laser‑welded seal isolates delicate gauge elements from corrosive, viscous, or clogging process fluids—without adding bulky adapters or costly hardware.

Manufactured by leading pressure gauge manufactures in Gujrat India, the seal delivers industrial‑grade reliability at an economical price point, making it a smart upgrade for OEM equipment, laboratory skids, and compact process panels.

Key Performance Highlights

Compact Welded Body – Zero Compromise on Integrity

• Laser‑Welded Housing

A continuous seam joins the diaphragm to the seal body, forming a leak‑tight barrier that withstands thermal cycling and vibration.

• Minimal Dead Volume

Flush internal geometry prevents residue build‑up, ensuring fast, accurate pressure transmission even with viscous or particulate‑laden media.

• 316 L Stainless Steel Wetted Surfaces

Excellent corrosion resistance for chemicals, solvents, and hygienic fluids alike.

Why This Miniature Seal Makes a Big Impact

1. Economical & Lightweight – Ideal for OEMs or retrofits where cost and panel weight must stay low.
2. Direct Assembly – Threads straight onto a small‑dial gauge with no capillaries or adaptors; reduces measurement lag and simplifies installation.
3. Broad Temperature Window – Silicone DC 200 fill maintains stable response from cold‑room environments to hot‑process lines.
4. Versatile Range – Covers both vacuum and moderate pressure applications in a single model.

Typical Applications

• Skid‑Mounted Analytical Equipment – pH dosing panels, chlorine monitoring units
• Food & Beverage Fillers – Syrup and sauce lines where cleaning agents could damage bare gauges
• Pharmaceutical Pilot Plants – Small‑volume reactors requiring sterile, dead‑leg‑free pressure pickup
• Laboratory & R&D Benches – Compact test rigs needing corrosion‑resistant, accurate pressure control
• OEM Machinery – Compressors, pumps, and hydraulic tools with restricted instrument bays
