Product Overview
The Dwyer 2813-WP I/P transducer uses a closed-loop pressure feedback system to carefully control pneumatic output while compensating for fluctuations in supply pressure, temperature, mounting angle and vibration. This makes it suitable for demanding industrial installations, including applications where the transducer is field mounted directly on a valve.
A piezoceramic actuator with a protective covering provides a continuous barrier against impurities and humidity, supporting reliable operation in demanding environments. The Series 2800 design is field reversible and incorporates a NEMA 4X enclosure, with CSA and FM approvals for intrinsically safe applications.
The 2813-WP accepts a 4-20 mA loop-powered input and produces a proportional 3-15 psig (0.2-1.0 bar) pneumatic output. Its output capacity reaches 4.5 scfm at 25 psig supply and 12.0 scfm at 100 psig supply.
Installation is flexible, with input and output ports available on both the front and rear of the unit. The electrical connection is 1/2" female NPT, while the pressure connection is 1/4" female NPT. External zero and span adjustments allow the transducer to be calibrated in the field.
The housing is constructed from chromate-treated aluminum with epoxy paint and is rated for operation from -40 to 160°F (-40 to 71°C). With a compact weight of approximately 0.8 lb (0.37 kg), the 2813-WP is suitable for valve, panel and remote mounting applications where space and installation flexibility matter.

Who This Product Is Best For
The Dwyer 2813-WP is suited for process, HVAC and industrial control applications requiring an intrinsically safe current-to-pressure signal converter.
It is particularly useful for systems where a 4-20 mA electrical control signal must be converted into a 3-15 psig pneumatic signal for a valve positioner, actuator or other pneumatic final control element.
The compact Series 2800 construction also makes it suitable for field-mounted valve applications, panel installations and remote mounting, depending on the system configuration.
How to Specify & Commission It
- Confirm that the 3-15 psig (0.2-1.0 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 air supply and pneumatic output through the 1/4" female NPT pressure connection.
- Ensure the air supply 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.
