T1000 Electro Pneumatic Converter Order
An order for the Type 1000 pattern, the force balance instrument with an integral volume booster rated at 12 SCFM (339 SLPM) at midrange.
Marsh Bellofram Type Transducer Type 1000 force balance converters with integral volume boosters
What The Customer Needed
The actuators on this job were large enough that flow, not accuracy, was the limiting factor. A compact transducer would have stroked them too slowly for the control strategy.
How It Was Built
The Type 1000 was selected on its flow figure rather than its accuracy figure, since the integral booster is what lets it feed an actuator directly without a separate relay in the line.
What The Photographs Show
Supply air was regulated to sit above the maximum output as the datasheet requires, and each unit was calibrated with the supply held steady. The photographs show the batch on the bench with the air and signal connections made.





How It Finished
Actuators stroking at the speed the control strategy assumed, from a transducer that did not need a booster relay behind it.

Can this configuration be supplied under our own brand
Yes. Nameplates are printed to customer artwork and part numbering and checked against the build before fitting.
How is a batch kept consistent
The whole quantity is built in one run and calibrated consecutively on the same bench against the same standard current generator and 0.1 class pressure gauge.
What is the specification on this order
Type 1000 force balance converters with integral volume boosters.
Can we order a different range in the same body
Yes. The published selection table or coding system for this pattern lists the available input signals, output ranges and terminations.
