Overview
ControlAir's Dahl P200 and P290 P/I transducers are designed for converting pneumatic signals into electrical current with high accuracy and reliability. These devices are suitable for various industrial applications, including hazardous environments.

Specifications

• Inputs: Accepts instrument air at 3-15, 3-27, or 6-30 psig.
• Outputs: P200 offers 4-20 mA and 10-50 mA outputs; P290M provides 4-20 mA output.
• Accuracy: ±0.15% of span guaranteed; typical accuracy is ±0.10%.
• Temperature Range: Operating from -40°F to 161°F for P200 and -40°F to 167°F for P290.
• Protection: Includes reverse polarity, transient, and over-current protection.

Features

• Non-interactive calibration and RFI immunity.
• Explosion-proof housing for P200, suitable for hazardous locations.
• P290 offers high-density DIN rail adapters for space-saving installations.

Principles of Operation
The transducers use a solid-state, piezo-resistive transducer configured as a Wheatstone Bridge. Pressure applied to the transducer causes an imbalance, which is converted into an electrical signal.

Approvals and Certifications
The P200 is FM approved and CSA certified for various hazardous locations, including explosion-proof and dust ignition-proof environments.

Warranty
ControlAir products are warranted for 18 months against defects in materials and workmanship, with liability limited to repair, replacement, or refund.
