The Setra 204 is a high accuracy gauge and absolute pressure transducer, sold by Setra as their standard reference instrument for the test and measurement field. It has been around for decades and is a common sight in labs and test benches where the pressure reading itself needs to be trustworthy, not just adequate.
It uses a solid one-piece stainless steel sensor with variable capacitance sensing technology, giving accuracy of ±0.073% FS under standard conditions (±0.14% FS on units above 5,000 PSI) and a response time of under 1 millisecond. Pressure ranges run from 0-25 PSIG up to 0-10,000 PSIG in gauge, absolute or differential configurations, plus a 0-14.7 PSIV vacuum option. Output is available as 0-5VDC (standard), 0-2.5VDC, 1-5VDC, 1-6VDC, 0-10VDC, or 1-10VDC, on 22-30VDC excitation (24VDC normal) with reverse polarity protection. Overpressure ratings scale with the range ordered, for example 50/150 PSI proof/burst on the 25 PSIG range up to 11,000/12,500 PSI on the 10,000 PSIG range.
From our experience, this is specified for universal high precision pressure measurement, research and test work, vacuum systems, dynamometers, and engine test benches. Before we quote this, we would normally check the pressure range, output signal, and configuration (gauge, absolute or differential) needed. Hope this helps.
