Product Description

The ESP Pressure Scanner is a miniature electronic differential pressure measurement device consisting of a set of silicon piezoresistive pressure sensors, one for each pressure port. The sensors are mounted on a common hybrid ceramic substrate using a proprietary technology that maximizes long-term stability. The output of the sensors is electronically multiplexed through a single on-board instrumentation amplifier using binary addressing at rates up to 70,000 Hz.
The ESP scanner also contains a two-position calibration manifold driven by transient pulses that control pressure. When placed in the calibration position, all sensors are connected to a common calibration pressure port. A series of accurately measured pressures can be applied through this port to characterize the sensors under the conditions they are subjected to. Proper and regular in-line calibration can maintain static errors of ±0.03% or more of the full scale (FS) pressure range. The calibration manifold automatically switches between two commonly used reference pressures to ensure a stable reference pressure is applied during calibration. The calibration manifold includes a visual position indicator and features a dynamic O-ring seal design for high reliability and easy field serviceability.
