Setra 2091200PG2M11A1 Pressure Transducer

The Setra 2091200PG2M11A1 Pressure Transducer is an industrial-grade capacitive sensor designed for contractors requiring high stability and precision in HVACR monitoring and process control systems. Engineered with a 0 to 200 PSI gauge pressure range, this unit features 17-4 PH stainless steel wetted materials, ensuring corrosion resistance when used with various liquids and gases. Its 4-20 mA current output is loop-powered, operating on a 9 to 30 VDC supply, and provides a robust signal even over long cable runs, minimizing electrical noise interference in demanding mechanical rooms.

This OEM-quality pressure sensor includes a 1/4" NPT male pressure fitting for standard mechanical threading and a 2-foot multiconductor cable with a 1/2" conduit cover for secure electrical termination. With an accuracy of ±0.25% Full Scale, it delivers the reliable data logs necessary for building automation systems and hydraulic pressure tracking. The rugged Valox housing protects the internal capacitive sensing element, which features a patented overpressure stop capable of withstanding spikes up to 16X the rated range without catastrophic failure.

• High Overpressure Protection: Features a patented internal stop to protect the sensor against hydraulic shocks and system pulsations.
• Stainless Steel Durability: 17-4 PH stainless steel wetted parts provide excellent media compatibility for water, refrigerants, and non-corrosive gases.
• Industry-Standard Signal: Reliable 4-20 mA output ensures seamless integration with standard PLCs and HVAC controllers.
• Compact Footprint: Small Form-factor design allows for installation in tight manifolds and OEM equipment enclosures.
• Wide Temperature Support: Operational performance maintained across a wide ambient range of -40° to 185°F.

• How do I wire this transducer to my controller? This is a 2-wire, loop-powered device. Connect the Red lead to the positive excitation (+) and the Black lead to the control input/return (-) of your loop.
• Is this sensor compatible with ammonia refrigerants? While 17-4 PH stainless steel is highly durable, always verify specific chemical compatibility for ammonia applications for long-term reliability.
• Can it be installed outdoors? Yes, when used with the integrated conduit cover and proper weather-tight fittings to protect the electrical terminations.
