The Setra AccuSense Model ASM is a high perf ormance pressure transducer designed for accurate, reliable pressure measurements. Th e ASM has a high level analog output signal, excellent stability, and secure calibration to help meet the increasing demands of today's complex test systems. The Setra AccuSense Mode l ASM pressure transducer is ideal for high performance industrial, laboratory, a nd engine test ce ll applications.

The Setra AccuSense Model ASM pressure transdu cer offers ranges from vacuum to 1000 psi in gauge or absolute pressures. An accuracy of up to ±0.05% FS (End-Point Accuracy) or 0.1% of reading ensures stable, re peatable and precise pressure read ings throughout the testing process.

## The ASM total error band is < ±0.25% FS, minimizing therma l error. This exceptional performance is achieved by combining Setra's unique electronic circuitry with its patented digital

sensor.

The Setra AccuSense Model ASM pressure trans ducer has a choice of 0 to 5 VDC, 0 to 10 VDC, or 4 to 20 mA output. A wide range of pressure and electrical connectors are also offered, maximizing the adaptability of the ASM to a wide variety of test system applications. The ASM is a durable pressure transducer that features all stainless st eel construction, groove design, and hydrophobic porous plug at top of unit protects the rece ssed air vent from contaminants in
industrial environments. The ASM offers sta ndard overpressure protection up to 2X proof pressure and a patented high overpressure pr otection option that en ables up to10X proof

pressure.

The Setra ASM eliminates the manual trim pots t ypically used on pressure transducers in order to ensure tamper-proof calibra tion. The optional SecureCal calib ration accessory allows quick and easy digital calibrations.
