PR-276 Series Overview

100% Solid‑State, Micro‑Machined, Glass‑on‑Silicon, Ultra‑Stable Capacitance Sensor
Duct Pressure Transducer and Static pressure Tip Integrated as One Unit
NIST Traceable Calibration

The PR‑276 incorporates sophisticated integrated circuits and a new micromachined glass‑on‑silicon (Gl‑Si) capacitance sensor to not only provide a high level, fully conditioned and temperature compensated output, but also to offer up to three (3) field selectable pressure ranges in one unit. The field selectable feature eliminates costly inefficiencies by providing a single unit which can be configured to cover all the pressure ranges for a particular application. For instance, 1.25", 2.50" and 5.00" wc are in one unit.
