Kolkata anchors eastern India's heavy industry — steel and metals, engineering and foundries, jute and textiles, chemicals and fertiliser, thermal power and a major port. Much of it is old, hot, hard-duty plant where instruments have to survive rather than merely measure.
Kolkata and the wider eastern belt — Howrah, Durgapur, Asansol, Haldia and the Hooghly industrial corridor — carry some of the country's oldest and heaviest industry. Steel, alloys and metals; foundries and heavy engineering; jute and textiles; chemicals and fertiliser; thermal power; and the Haldia refinery and port. This is hot, hard, continuous duty — furnaces, boilers, hydraulic presses, aggressive media and high pressures — the environment in which a wrongly-specified instrument fails soonest and most visibly.
That is precisely the duty we manufacture for. Furnace and foundry thermocouples with the right sheath and protection tube; high-pressure steam and boiler gauges with siphons and gauge savers; hydraulic press gauges that survive spikes; diaphragm sealed instruments for corrosive chemical and fertiliser media; and, for the Haldia belt, certified transmitters and remote seals. All of it built, ranged and calibrated at our works and shipped with traceable certificates for the plants that audit measurement.
We are a Faridabad manufacturer supplying Kolkata pan-India by freight. For heavy eastern duty the value is in specifying the instrument to survive the process — the correct furnace protection, the correct steam fitting, the correct wetted material — so that what arrives works and keeps working.
Kolkata and eastern India are a regular pan-India dispatch for us:
Foundries, engineering and metals — furnace thermocouples, hydraulic and high-pressure gauges, and pressure switches.
Steel, alloys and heavy engineering — high-temperature thermocouples with ceramic wells, high-pressure gauges and boiler instrumentation.
Certified pressure and DP transmitters, remote seals, diaphragm seals and instruments specified to area classification.
Chemicals, engineering and processing — diaphragm sealed instruments, DP monitoring and transmitters.
Steam gauges with siphons, temperature sensors and pressure instruments on processing machinery.
High-pressure steam and feedwater gauges, drum level instruments and DP transmitters across the cycle.
Heavy, hot, continuous duty defines the east. These are the Kolkata sectors we specify for.
High-temperature furnace thermocouples with ceramic protection, high-pressure hydraulic gauges and boiler instrumentation.
High-pressure steam and feedwater gauges with siphons, drum level instruments and safety-critical pressure measurement.
Furnace thermocouples, hydraulic press gauges with snubbers and utility instrumentation.
Diaphragm sealed instruments for corrosive and crystallising media, DP monitoring and temperature control.
Steam gauges with siphons, process temperature sensors and pressure instruments on mill machinery.
Certified pressure and DP transmitters, remote seals and instruments specified to area classification.
Everything below is manufactured, ranged and calibrated at our Faridabad works and delivered to Kolkata on the terms shown further down this page.

If you are not sure which instrument suits your duty, send us the media, the working pressure or temperature, the process connection and the environment on WhatsApp. We will size it — and if a cheaper instrument would do the job, we will tell you that too.
Most instrument failures are not manufacturing defects — they are specification mistakes. These are the ones we see most often in Kolkata.
In steel and foundry duty the protection tube takes thermal shock, scale and mechanical abuse. Match the sheath and ceramic protection to the atmosphere and temperature, and the thermocouple stops being a monthly consumable.
Live steam cooks a gauge movement in weeks. A pigtail or coil siphon fills with condensate and protects it — a trivial cost against a gauge you keep re-buying in a jute mill or a power house.
On boilers and hydraulic systems the gauge is part of the safety case — correct range, over-range protection, blow-out back and the right connection are not optional. We specify them as standard.
Aggressive and crystallising media destroy direct-connected instruments. Diaphragm seals with the correct wetted material and fill fluid keep the process off the instrument.
Steel, power and refinery plants audit measurement. Tell us the documentation you need with the order and the instrument arrives complete and audit-ready.
A captive power plant in the Durgapur belt was replacing steam-header pressure gauges far too often, keeping a stock of cheap gauges and swapping them as they failed — treated as an unavoidable cost of a steam plant.
The gauges were connected directly to the header with no siphon. Live steam was entering each socket and cooking the movement; no dry gauge survives that, and the cheaper replacements simply failed faster. It was an installation problem wearing the disguise of a gauge-quality problem.
We fitted coil siphons and gauge savers, ranged the gauges to sit at two-thirds of scale, and used filled gauges on the pulsating points. The steam condensed in the siphon loop and protected the movement. The frequent replacements stopped and the gauge spend collapsed — fixed by a fitting worth a fraction of the gauge.
Eastern India's heavy plants waste a lot of instrument spend not on premium instruments but on cheap ones bought repeatedly, because the installation was never specified. A steam gauge without a siphon, a furnace thermocouple with the wrong protection, a corrosive line with a direct gauge — each fails predictably, and the usual response is a cheaper replacement that fails just as fast.
We would rather specify it to survive once. Supplying by freight from Faridabad, what we bring is the correct furnace protection, the correct steam fitting, the correct wetted material — the specification that makes an instrument last in hard duty, arriving complete and documented.
Heavy-duty and stock instruments freighted to Kolkata with tracking.
Furnace protection, siphons, remote seals and high-pressure builds specified correctly.

Specification and sizing before you order.
Instrumentation supply, calibration and service across the region.
Vedika Instruments supplies Kolkata and eastern India's heavy industry — steel and metals, foundries and engineering, jute and textiles, chemicals and fertiliser, thermal power and the Haldia refinery and port, across Howrah, Durgapur, Asansol and the Hooghly corridor. This is hot, hard, continuous duty where instruments must survive: furnace thermocouples with the right protection, high-pressure steam and boiler gauges with siphons, hydraulic press gauges that take spikes, diaphragm sealed instruments for corrosive media, and certified transmitters for Haldia — every item built, calibrated and documented.
We manufacture in Faridabad and supply Kolkata pan-India by freight. In heavy duty the instrument's first job is to last, so what we bring is the specification that makes it survive — the correct furnace protection, the correct steam fitting, the correct wetted material — arriving complete and audit-ready. Specified to survive once beats a cheap replacement bought over and over.
Send a tag list, a datasheet or a photo of the instrument you are replacing. We will size it and quote it.
