Product Overview
The Dwyer 2816-WP I/P transducer uses a closed-loop pressure feedback system to maintain accurate pneumatic output while correcting for changes in supply pressure, temperature, mounting angle and vibration. This makes it well suited to demanding field applications, including mounting directly on control valves.
A piezoceramic actuator with a protective covering provides continuous protection against impurities and humidity. The Series 2800 design is field reversible and incorporates a rugged NEMA 4X enclosure, making the 2816-WP suitable for industrial environments where enclosure protection and intrinsic-safety approvals are required.
The transducer accepts a 4-20 mA loop-powered input and provides a proportional 6-30 psig (0.4-2.1 bar) pneumatic output. Its output capacity reaches 4.5 scfm at 25 psig supply and 12.0 scfm at 100 psig supply.
For installation flexibility, the unit provides input and output ports on both the front and rear. The electrical connection is 1/2" female NPT, while the pressure connection is 1/4" female NPT. External zero and span adjustments allow field calibration.
The chromate-treated aluminum housing with epoxy paint provides a durable enclosure for applications operating across a temperature range of -40 to 160°F (-40 to 71°C).

Who This Product Is Best For
The Dwyer 2816-WP is suited for process, HVAC and industrial control applications requiring reliable current-to-pressure signal conversion.
It is particularly useful where a 4-20 mA control signal needs to drive a pneumatic valve positioner, actuator or other final control element, especially in installations requiring NEMA 4X protection and FM/CSA intrinsic-safety approvals.
How to Specify & Commission It
- Confirm that the 6-30 psig (0.4-2.1 bar) output range matches the requirements of the final control element.
- Connect the 4-20 mA loop-powered input using the 1/2" female NPT electrical connection.
- Connect the pneumatic supply and output through the 1/4" female NPT pressure connection.
- Apply an appropriate air supply, ensuring it is at least 5 psig above the maximum required output and does not exceed 100 psig.
- Use the external zero and span adjustments to complete field calibration as required.
