T1000 Electro Pneumatic Transducer Order
A catalogue order for the general purpose class of the Type 1000, the most commonly specified of the four build classes.
Marsh Bellofram Type Transducer Type 1000 general purpose build, 4-20 mA input
What The Customer Needed
The buyer's plant runs valve actuators, damper drives and air cylinders on the same instrument air system, and wanted one pattern that could cover all three rather than a different transducer for each.
How It Was Built
The Type 1000 application list covers exactly that spread: valve actuators, damper and louver actuators, valve positioners, controllers, relays, air cylinders, clutches and brakes. One pattern, one footprint, one spare.
What The Photographs Show
Units were calibrated direct acting as the factory standard, with the field reversible feature left available so that any unit could later be run reverse acting by reversing the signal lead polarity and recalibrating.





How It Finished
A single transducer pattern covering three different kinds of final element on one site.
