Bell Engineering & Marketing
Over 40 years of precision gauge manufacturing from Ahmedabad, Gujarat — trusted by thousands of industries across India and exported globally.
India's Trusted Pressure Gauge Manufacturer Since 1984
Bell Engineering & Marketing was established in 1984 in Ahmedabad, Gujarat, with a clear mission: to manufacture high-precision, durable and affordable industrial measurement instruments.
Today, we are an ISO 9001:2015 certified manufacturer supplying pressure gauges, temperature gauges, vacuum gauges and specialty instruments to thousands of clients.
Our manufacturing facility features modern CNC machinery, an in-house calibration laboratory with traceable standards, and a rigorous quality management system.
We work with three distinct groups of buyers: plant engineers and procurement teams ordering standard catalogue gauges for maintenance and new installations; OEMs and panel builders who need custom-branded, private-label instruments built to their drawing; and international distributors and EPC contractors sourcing bulk export volumes with full documentation.

Our Story
From a small precision-instrument workshop in Ahmedabad to a pressure gauge manufacturer exporting worldwide.
Bell Engineering & Marketing began in 1984 in Ahmedabad, Gujarat — a region that has since grown into one of India's major industrial and manufacturing hubs. The company started with a focus on Bourdon tube pressure gauges for local hydraulic and pneumatic equipment builders, and gradually expanded into temperature gauges, vacuum gauges and differential pressure instruments as customer requirements diversified.
Over four decades, that growth has been driven by two consistent priorities: measurement accuracy that plant engineers can rely on, and manufacturing discipline that supports both single-piece orders and large OEM production runs. That same approach guides Bell Engineering today as an ISO 9001:2015 certified pressure gauge manufacturer and exporter.
Bell Engineering & Marketing is established in Ahmedabad, Gujarat, manufacturing Bourdon tube pressure gauges for local industry.
Manufacturing expands to include temperature gauges, vacuum/compound gauges, differential pressure gauges and diaphragm-seal instruments.
An in-house calibration and testing laboratory is set up, allowing 100% pre-dispatch testing against traceable reference standards.
Bell Engineering formalises its quality management system and is certified to ISO 9001:2015 across design, manufacturing and testing.
Bell Engineering begins exporting pressure gauges and temperature gauges to the GCC region, building toward supply into 20+ countries today.

Why Choose Bell Engineering as Your Pressure Gauge Supplier
What plant engineers, OEM buyers and export distributors consistently tell us matters most when they switch to Bell Engineering.
1. Single-Source Range
Pressure gauges, vacuum gauges, temperature gauges, differential pressure gauges and diaphragm gauges from one ISO-certified manufacturer — fewer vendors to qualify and manage.
2. OEM & Custom Capability
Custom dial printing, branded cases, non-standard ranges and connection types manufactured to your specification, not just catalogue selection.
3. Documented Traceability
Calibration certificates, material test certificates and batch traceability provided on request — built for ISO, IATF and plant QA audit requirements.
4. Export-Ready Documentation
Commercial invoice, packing list, certificate of origin and test certificates prepared for smooth customs clearance in export markets.
5. Engineering Support
Talk directly to our engineers about range selection, media compatibility and connection type before you order — not a generic sales script.
6. 40+ Years of Continuity
One manufacturer, one facility, four decades of production history — the kind of supply continuity long-term maintenance contracts and OEM agreements depend on.

Manufacturing Capacity & Engineering Expertise
Production scale and engineering depth that support single-unit orders, project-based supply, and recurring OEM volumes alike.
Production Capacity
Multi-line production capacity across pressure, vacuum and temperature gauge ranges, able to scale from small trial-order quantities to recurring bulk and OEM production schedules. Exact capacity and lead time depend on gauge type and specification — confirmed at enquiry stage.
Engineering & Application Support
Our engineering team reviews operating pressure, media compatibility, ambient conditions and connection requirements before recommending a gauge — reducing the risk of premature failure from incorrect range or material selection.
Product Development
New dial layouts, connection variants and case configurations are developed in response to real customer and OEM requirements, then validated through our in-house testing process before release.
Custom Engineering to Drawing
For OEM and panel-builder customers, gauges can be engineered to a supplied drawing or specification sheet — range, dial branding, connection type, wetted material and case finish.
Quality Assurance & In-House Calibration Laboratory
Quality control at Bell Engineering runs through three checkpoints: incoming raw material inspection, in-process checks during Bourdon tube forming and assembly, and 100% final testing before dispatch on our in-house dead-weight tester and hydraulic/pneumatic calibration rig.
Every finished gauge is checked at multiple points across its full scale before it leaves the facility. Calibration certificates, material test certificates and batch traceability documentation are issued on request, supporting ISO, IATF and plant QA audit requirements.

OEM & Private Label Pressure Gauge Manufacturing
As an OEM pressure gauge manufacturer, Bell Engineering produces gauges to a customer's own specification rather than only supplying from a fixed catalogue — covering custom pressure ranges, dial layouts, connection types, case materials and accuracy classes.
For private label / white-label orders, we manufacture under your brand name and dial artwork, with your company details on the case and documentation — a common arrangement for panel builders, instrumentation distributors and equipment manufacturers who want a consistent house brand across their product line.
