Setra 204 Specifications

Model 204

High Accuracy Gauge & Absolute
Pressure Transducer

Setra’s Model 204 is the “standard” for the measuring gauge and
absolute pressure in the test and measurement industry. Decades worth
of installations have helped the 204 build a reputation of reliability and
remains the trusted choice for critical installations. The 204 delivers a high
performance ±0.073% FS accuracy over a wide temperature range which
outperforms competitive transducers in the mid to high pressure market.
The 204 offers multiple options to meet both simple and demanding
application requirements that are not provided on competitive transducers.

Long-term reliability

The Model 204 pressure transducer uses a simple and reliable variable
capacitance sensor design. The 204 provides repeatable and dependable

readings in rugged applications through its efcient sensor design.

Accuracy & performance

The Model 204 is a test and measurement grade transducer for mid to
high pressure ranges. The 204 covers a large selection of pressure ranges
with ±0.073% FS accuracy over a wide temperature range. The Model 204
provides response time of <1 ms, exceeding the performance of many
competitors.

Features

• Ideal for high accuracy applications

• Excellent thermal effects

• Highly congurable design

• ±0.073% FS accuracy

• 0-5 VDC

• Fast response, less than 1 ms

• Low output noise

• Solid one-piece stainless steel sensor

• Meets CE conformance standards

Applications

• Hight accuracy general purpose

• R&D test and measurement

• Vacuum systems

• Dynamometers

• Engine test cells

Customization is standard

Unlike many competitors, the 204 offers many mechanical and electrical
options that can be integrated into existing system designs. These options
reduce engineering design time, allowing for earlier project completion
and quicker time to market.

Zero output factory set to within ±10mV. Span (Full Span) output factory set to within ±10mV.

Note: Both output leads are normally 1.6 VDC above the negative excitation lead at zero pressure.
Either negative excitation or negative output should be connected to case (ground). But both leads
cannot be connected to case (ground). Unit is calibrated at the factory with the negative excitation
connected to case (ground.)
