Allen-Bradley 80026-619-01-R Pressure Transducer

Product Overview

The 80026-619-01-R is a pressure sensor transducer manufactured by Allen-Bradley (Rockwell Automation). It converts process pressure into a standard 4–20 mA or 0–10 VDC output signal for integration with PLC, DCS, and SCADA systems. With a stainless steel housing and wide pressure range, this transducer delivers reliable measurement in hydraulic, HVAC, water treatment, and general industrial automation applications.

FAQ

Q: What is the accuracy class of the 80026-619-01-R?
A: The transducer delivers ±0.25% of full-scale accuracy across the calibrated pressure range.

Q: Can the output signal be configured in the field?
A: Output selection (4–20 mA vs. 0–10 V) is typically factory-configured. Verify your part number suffix or consult the datasheet for field-configurable variants.

Q: Is this transducer suitable for outdoor installation?
A: The -40°C to +85°C temperature range and stainless steel housing support outdoor use. Add a weatherhead or enclosure for additional moisture protection.

Installation Guide

• Mount the transducer on a process tap or manifold using Teflon tape or appropriate thread sealant.
• Connect 24 VDC power to the supply terminals and the signal wire to the PLC analog input card.
• For 4–20 mA loops, verify loop resistance does not exceed the transducer's maximum load rating.
• Apply a known pressure reference (calibrator or deadweight tester) and verify output at 0%, 50%, and 100% span.
• Zero and span trim if adjustable trim pots are provided on the transducer body.

Selection Tips

• Pressure Range: Select a range where normal operating pressure sits at 50–75% of full scale for optimal resolution and overpressure protection.
• Output Compatibility: Match 4–20 mA to PLC analog input cards with 250 Ohm burden resistors, or 0–10 V to high-impedance voltage inputs.
• Media Compatibility: Verify wetted materials (stainless steel diaphragm, O-rings) are compatible with your process fluid.
• Response Time: For pulsating flows or rapid pressure cycling, specify a transducer with dampening or snubber accessories.
