Pressure Gauge & Pressure Transmitter

Introduction

The pressure measuring cell converting the pressure into an electrical signal is the heart of the pressure sensor.

Pressure transmitter

Categorization of Pressure Instruments:

• Pressure gauges

• Pressure transmitters

The pressure gauges

The pressure gauge instrument is used for measuring the condition of a fluid (liquid or gas).

Pressure gauge accessories are as follows:

• Diaphragms

• Bellows

• Bourdon Tube

Diaphragms

Bellows

Bellows (fig. 3) are made with a number of convolutions from a soft material and one end of it is fixed, whenever air can go through a port. The other end of the bellows is free to move.

Bourdon Tube

It is basically consisted of a C-shaped hollow tube, whose one end is fixed and connected to the pressure tapping, the other end free.

Pressure transmitters

A pressure transducer, often called a pressure transmitter, is a transducer that converts pressure into an analog electrical signal.
