500AC Electro Pneumatic Transducer Order
A straight catalogue order for the 500-AC: the 4-20 mA input, 3-15 psi output, 180 ohm configuration that matches a standard 20-100 kPa actuator spring.
Controlair Type Transducer 500-AC configuration, standard EAA nameplate
What The Customer Needed
The buyer needed a quantity large enough to standardise their instrument store on one transducer part number, which meant every unit had to be identical and the nameplate data had to be legible for the technicians who would later fit them.
How It Was Built
A single build of the one configuration, each unit labelled with input, output and supply pressure so the specification can be read off the valve without paperwork.
What The Photographs Show
Units were calibrated individually and then grouped for a batch check. The photographs show the finished transducers packed in rows, the arrangement used for the final visual and label inspection before cartoning.





How It Finished
One part number covering the buyer's standard-spring valve population, replacing several incompatible spares.
