Setra 204 Data Sheet

Model 204

High Accuracy Gauge & Absolute

Pressure Transducer

Setra’s Model 204 is the “standard” for 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 oers 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 e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.

Customization is Standard

Unlike many competitors, the 204 oers 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.)
