Hemkund Automation is the authorised distributor of Marsh-Bellofram USA in India — bringing America's most trusted electropneumatic transducer technology directly to Indian process industries.
The industry's best-selling electropneumatic transducer — a proven standard for over four decades. Converts a 4-20mA or voltage signal into a proportional pneumatic output to control valves, actuators, positioners and more.
The Type T-1000 Transducer is an electro-pneumatic force-balance device that reduces supply pressure to a regulated output pressure directly proportional to an electrical input signal. It accepts a wide range of supply pressures — from a minimum of 3 PSIG above the maximum output up to 100 PSIG (6.9 BAR).
An integral pneumatic volume booster provides high flow capacity up to 12 SCFM (339 SLPM), eliminating the need for an external booster relay in most applications. All models are field reversible — switch between direct and reverse acting simply by reversing polarity.
Zero and Span adjustments are on the front face of the unit — accessible without removing the transducer from the line or breaking process connections.

All variants share the same proven T-1000 platform — select the variant that fits your application:
Complete specifications, dimensional drawings, ordering information and agency approvals for all T-1000 variants
For high-flow applications, manifold mounting or where the most advanced transducer architecture is required — the T-1500 and T-2000 extend the Marsh-Bellofram range.
The T-1000 has been the standard I/P transducer in process control for over four decades. More T-1000 units are installed globally than any other electropneumatic transducer.
Every Marsh-Bellofram transducer is manufactured in Newell, West Virginia, USA — to the rigorous quality standards expected of the world's most critical process industries.
FM, CSA, ATEX and CE approvals across the range. Suitable for general purpose, NEMA 4X, intrinsically safe and explosion-proof classified area installations worldwide.
Tested to less than 0.5% of span repeatability with less than 1.0% hysteresis — performance specifications that have remained the benchmark for three decades.
As the authorised Indian distributor, Hemkund Automation stocks T-1000 units for immediate dispatch — no long international lead times or import delays.
Our Pune-based team provides full pre-sales sizing assistance, installation guidance and post-sales technical support for all Marsh-Bellofram products in India.
