Setra 2301100PD2F11B Pressure Transmitter

The Setra 2301100PD2F11B Pressure Transmitter is a high-accuracy wet-to-wet differential pressure transducer engineered for demanding HVACR and industrial process control. With a 0 to 100 PSID unidirectional pressure range and a standard 4-20 mA output, this unit provides precise monitoring of liquid and gas media in hydronic systems. The rugged construction utilizes 17-4 stainless steel wetted parts and Viton bleed screw seals to ensure chemical compatibility and long-term stability. Designed for professional installation, it features 1/4" NPT female pressure fittings and a NEMA 4 (IP65) enclosure, making it resilient against moisture and airborne contaminants. This capacitive pressure sensor maintains a ±0.25% full scale accuracy, providing the technical reliability required for critical differential pressure measurement in pump control, heat exchanger monitoring, and chiller plant optimization.

Key Benefits for Contractors

• High-Precision Monitoring: Achieves ±0.25% FS accuracy for superior control in variable speed pumping and flow measurement applications.
• Extreme Durability: The 17-4 PH stainless steel sensor and NEMA 4 housing protect internal components from harsh mechanical room environments.
• Simplified Maintenance: Equipped with standard Viton bleed screw seals to facilitate easier air purging and system commissioning.
• Industrial Integration: The 4-20 mA signal ensures seamless communication with building automation systems (BAS) and PLC controllers.
• Robust Overpressure Protection: Features high proofs of 350 psig (high port) and 250 psig (low port) to prevent sensor damage during system surges.

Common Questions

Is the Setra 2301100PD2F11B compatible with glycol systems?
Yes, the 17-4 stainless steel wetted materials and Viton seals are highly resistant to water/glycol mixtures commonly found in chilled water and heating loops.

Can this transmitter be used in outdoor environments?
The unit is housed in a NEMA 4 (IP65) rated enclosure, which provides protection against windblown dust and rain, making it suitable for sheltered outdoor installations.

What is the maximum line pressure this unit can handle?
While the scale is 100 PSID, the sensor is designed to handle significant line pressure; however, the cumulative high-side pressure should not exceed the 350 psig burst rating to ensure component integrity.
