Calibrating Pressure and Differential Pressure Instruments (AIC02)

In Instrumentation

Details

This lesson demonstrates the necessary steps for calibrating pressure instruments.

Prerequisites

This lesson is designed for participants familiar with the basic principles of calibration including the steps of a calibration procedure, common instrument errors, and the standards for instrument performance. An understanding of algebra is also recommended.

Description

This lesson demonstrates the necessary steps for calibrating pressure instruments. The lesson also identifies procedures and set-up equipment for pressure calibration.

Objectives

Set up a pressure transmitter, differential pressure transmitter, and a pressure gage for calibration with the appropriate input and output test equipment, proper connections, and mountings. Perform a five-point calibration check on an analog electronic pressure transmitter, a differential pressure transmitter, and a pressure gage. Identify zero shift, span error, combined error, and nonlinearity. Properly adjust pressure instruments to eliminate errors. Use a digital interface device to re-range a smart pressure transmitter.
