Overview

The sensors in the ESP-64HD electronic pressure scanner are mounted on a common hybrid ceramic substrate using a proprietary technique which maximizes long term stability. The outputs of the sensors are electronically multiplexed through a single onboard instrumentation amplifier at rates up to 70,000 Hz using binary addressing. The multiplexed amplified analog output is capable of driving long lengths of cable to a remote A/D converter. The ESP scanners also incorporate a two-position calibration manifold actuated by momentary pulses of control pressures. When placed in the calibrate 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, in place, at the condition to which they are being subjected. Proper and periodic on-line calibration maintains static errors within ±0.03% or better of the full scale (FS) pressure range. The calibration manifold automatically switches between two common reference pressures to ensure a stable reference is applied during calibration. The calibration manifold incorporates a visual position indicator and utilizes a dynamic o-ring seal design for high reliability and easy servicing in the field.
