Setra 2561150PG2M11 Pressure Transducer

The Setra 2561150PG2M11 Pressure Transducer is a rugged, industrial-grade sensor designed to provide precise gauge pressure measurement in demanding HVACR and process control environments. Engineered with a 0 to 150 PSI pressure range, this unit utilizes Setra’s proven capacitive sensing technology to ensure long-term stability and high resistance to environmental factors like shock, vibration, and EMI/RFI interference. The 4-20 mA output signal allows for seamless integration into standard building automation systems (BAS) and industrial controllers. Housed in a durable NEMA 4/IP65 rated die-cast aluminum enclosure, it features 17-4 PH stainless steel wetted parts for compatibility with a wide variety of non-corrosive liquids and gases. For simplified field installation, the Model 256 includes a 1/4" NPT male pressure fitting, internal terminal strips accessed via a removable cover, and adjustable zero/span potentiometers to maintain accuracy across the -40°F to +185°F operating temperature range.

• High Accuracy Performance: Delivers a ±0.25% FS accuracy rating, critical for precision monitoring in refrigeration and variable speed pump applications.
• Rugged NEMA 4 Enclosure: The weatherproof die-cast housing protects internal electronics from moisture and debris, making it ideal for outdoor HVAC mechanical rooms.
• NIST Traceable Calibration: Built to meet rigorous industry standards (ANSI-Z540-1), ensuring reliable and repeatable pressure monitoring.
• Broad Media Compatibility: The stainless steel sensor diaphragm supports universal application with water, hydraulic fluids, and many refrigerants (hydrogen excluded).

Is this transducer compatible with standard 24VDC loops?
Yes, the 4-20 mA current output is designed for a two-wire loop-powered configuration, typically operating on a 9 to 30 VDC excitation range with an 800-ohm maximum load.

Can I adjust the zero and span settings in the field?
Absolutely. The Setra Model 256 features internal potentiometers accessible under the removable cover, allowing technicians to fine-tune the signal for specific site conditions.

What type of electrical connection does this unit use?
The unit utilizes internal terminal strips for secure wiring and includes 1/2-inch internal threaded conduit ports for standard electrical termination.
