Setra 2301025PD2F11B Pressure Transmitter

The Setra 2301025PD2F11B is a high-accuracy wet-to-wet differential pressure transmitter engineered for demanding HVACR and industrial applications. Built on the proven Setra Model 230 platform, this unit features a 0 to 25 PSID unidirectional pressure range and utilizes a single-diaphragm capacitive sensor. Unlike dual-sensor units that calculate differential pressure and are prone to line pressure errors, this true wet-to-wet transducer provides superior ±0.25% FS accuracy and a response time up to 20x faster than traditional oil-filled sensors. The 4-20 mA output ensures a stable linear analog signal over long cable runs, while the 1/4" NPT (F) pressure fitting and Viton bleed screw seals facilitate secure, leak-free integration with various gases and liquids. Housed in a NEMA 4 rated enclosure, the 2301-025PD-2F-11-B is designed for technicians who require reliable differential pressure measurement in process control, pump monitoring, or chilled water systems without the risk of internal fluid rupture.

Key Benefits:

• True Differential Pressure Performance: Single-diaphragm design eliminates line pressure effect for precise wet-to-wet pressure sensing.
• Enhanced Signal Integrity: The 4-20 mA current loop provides high noise immunity and remains accurate across wide temperature variations.
• Durable Construction: 17-4 PH stainless steel wetted parts and Viton seals offer compatibility with both liquid and gas media.
• Rapid Response Time: All-stainless capacitive sensor technology delivers nearly instantaneous data for real-time system adjustments.
• Field-Ready Reliability: Standardized 1/4 inch NPT threads and bleed port valves simplify air purging and manifold mounting.

Common Questions:

Can the Setra 230 be used for liquid and steam systems?
This transmitter is fully compatible with liquids and gases that do not react with 17-4 PH stainless steel, 300-series stainless, or Viton. It is highly recommended for chilled water and hydronic heating systems.

How do I handle air trapped in the lines?
The unit includes integrated Viton bleed screw seals on the housing. During installation, these should be utilized to purge air from the sensing chambers to ensure accurate differential pressure readings.

What is the maximum line pressure this unit can handle?
While the measuring range is 0-25 PSID, the Model 230 is typically rated for a total line pressure of up to 250 or 350 PSIG depending on the manifold configuration, protecting the sensor during common system spikes.
