Brand: Setra Systems

Description

Overview

The Setra 209 is an industrial and OEM pressure transducer engineered for plants and equipment builders who need dependable pressure signals at an affordable price point. Built around a capacitive sensing element, the Setra 209 delivers ±0.25% full-scale accuracy across pressure ranges from as low as 1 PSI up to 10,000 PSI, giving instrumentation engineers a single transducer family that can be specified across hydraulic systems, compressor control, industrial engines, and general HVAC/R equipment without switching sensor technologies between low and high pressure duty points.

With fast quotation turnaround and technical support, Seven Star LLC proudly supplies the Setra 209 pressure transducer to process plants, OEM equipment manufacturers, and industrial maintenance teams across the Sultanate of Oman, Muscat, and the wider GCC region.Seven Star LLC supplies this item on request with the manufacturer documentation, and availability and lead time are confirmed at quotation.

Measurement Principle of the Setra 209

The Setra 209 uses a variable capacitance sensing technology in which the process pressure deflects a stainless steel diaphragm positioned between two fixed capacitor plates. As pressure changes, the gap between the diaphragm and the reference plate changes proportionally, altering the capacitance in a highly linear and repeatable manner. This solid-state approach avoids the strain-gauge drift and welded-joint fatigue that limit the service life of older mechanical and piezoresistive transducer designs, giving the Setra 209 the stability required for continuous duty in demanding plant environments.

Because the sensing diaphragm and reference plate are all-stainless-steel wetted materials, the Setra 209 resists corrosion from a wide variety of process gases and liquids while maintaining its rated accuracy over the transducer’s operating life. The design incorporates a patented overpressure stop that lets the sensor withstand overpressure conditions up to 16 times the rated range without permanent damage, a critical benefit in hydraulic systems and reciprocating compressor applications where pressure spikes and pulsation are routine. The result is a transducer that resists nuisance failures without requiring costly external snubbers or surge protection.

Engineering Design of the Setra 209

Setra engineered the 209 with flexibility as a core design goal, offering a wide range of pressure fitting and electrical connector combinations to fit challenging OEM installation requirements without custom engineering. The transducer accepts common process fittings and is available with either a 4-20 mA current output or a voltage output, letting integrators select the interface that matches their existing control system without adding a separate signal converter. This flexibility minimizes engineering time during equipment design, allowing OEM manufacturers to reach production faster.

The Setra 209 operates on low-cost unregulated DC power, simplifying the power supply design for OEM control panels, and its rugged construction is rated for high shock and vibration applications typical of mobile and industrial engine platforms. With no seals or O-rings prone to leakage and no brazed joints susceptible to corrosion, the Setra 209 is built for long-term reliability in the field, and the unit carries CE and RoHS compliance for use across international projects.

Key Features

The Setra 209 pressure transducer combines industrial-grade construction with the flexibility OEM integrators require. Core capabilities include:

Exceptional ±0.25% full-scale accuracy across the complete Setra 209 product range.
True low-range sensor design supporting full-span ranges down to 1 PSI without additional signal amplification.
Pressure coverage extending up to 10,000 PSI for demanding hydraulic and compressor applications.
All stainless steel wetted materials for broad chemical and process fluid compatibility.
Patented overpressure stop rated to 16X the sensor’s rated range on select ranges.
Selectable 4-20 mA current output or voltage output to match existing control architecture.
Rugged design suited to high shock and vibration environments, including mobile equipment.
CE and RoHS compliant construction for use across regional and international installations.

Industrial Applications

Process plants and equipment manufacturers throughout the region specify the Setra 209 wherever a compact, reliable pressure signal is needed at a competitive installed cost. Hydraulic power units on construction and material handling equipment use the Setra 209 to monitor system pressure and protect pumps from cavitation, while compressor control panels rely on it to track suction and discharge pressure across multi-stage compression trains. HVAC/R equipment manufacturers integrate the Setra 209 into chillers and refrigeration packages destined for district cooling plants and commercial developments across Muscat, and industrial engine OEMs use it for oil and fuel pressure monitoring in generator sets deployed throughout Oman’s power and water infrastructure projects.

With engineering support in Muscat, Seven Star LLC supplies the Setra 209 to OEM panel builders, industrial maintenance contractors, and process engineering firms operating within the Sohar and Salalah economic zones, as well as to industrial clients throughout Muscat and the broader Sultanate of Oman.

About brand

Setra Systems, founded in 1967 and based in Boxborough, USA, builds pressure transducers for building air systems, clean spaces and industrial equipment. Seven Star LLC, an independent supplier in Oman, lists the Setra 264 low differential pressure transducer, the Setra 267 very low differential pressure transducer and the Setra 209 pressure transducer.

Setra pressure transducers listed here

The 264 and 267 measure small air pressure differences, the kind found across a filter, between two rooms or in a duct. The 267 comes in a NEMA 4 housing for wall or duct mounting, with an optional static pressure probe and LCD, and both are ordered by range, unidirectional or bidirectional span and output signal. The 209 is a different instrument: an industrial pressure transducer. The 264 and 267 use Setra's stainless steel capacitive sensing element.

Ordering Setra transducers: what we need

Setra part numbers are long because each character fixes a feature. Copy the full number from the label. If the label is gone, send the model (264, 267 or 209), pressure range and unit, whether the range is one-sided or plus and minus, output (voltage or 4-20 mA), supply, accuracy grade, and pressure and electrical connections. Projects in the GCC often specify a display or a duct probe on the 267, so mention those too.
