What is Bourdon gauge?
A Bourdon gauge is a mechanical device used to measure and display pressure. The gauge can be used for measuring pressure in both gas and liquid state systems. The bourdon gauge may appear like one of the least interesting pieces of equipment out there, but it is still one of the most widely spread.
Where are Bourdon gauges used?
The Bourdon and spiral tube are typically used on water systems and diaphragm units on both water and air systems. These mechanical devices can all be connected to a transmitter.
What is the working principle of Bourdon tube?
The Bourdon tube works on a simple principle that a bent tube will change its shape when exposed to variations of internal and external pressure. As pressure is applied internally, the tube straightens and returns to its original form when the pressure is released.
Who invented Bourdon gauge?
Eugene BourdonBourdon tube / Inventor
What is Burden pressure gauge?
Bourdon tube pressure gauges are used for the measurement of gauge pressures from 0.6 7,000 bar. They are classified as mechanical pressure measuring instruments, and thus operate without any supply voltage.
What are the types of Bourdon gauge?
Bourdon tubes come in three basic types: C-type, spiral-type, and helical-type.
Does Bourdon gauge measures absolute pressure?
Bourdon tubes measure gauge pressure, relative to ambient atmospheric pressure, as opposed to absolute pressure; vacuum is sensed as a reverse motion. Some aneroid barometers use Bourdon tubes closed at both ends (but most use diaphragms or capsules, see below).
What are the types of Bourdon tube?
Types of Bourdon Tubes
- C-type. C-type Bourdon gauge tube. This is the most commonly found tube.
- Spiral type. Spiral Bourdon Tube. This type of Bourdon tube is spiral in shape and suitable for pressures up to 28,000 kilopascals.
- Helical type. Helical Bourdon tube.
When was the Bourdon gauge invented?
Eugene Bourdon (1808–1884) was a brilliant French watchmaker and engineer who invented the Bourdon gauge in 1849. This revolutionary new pressure measurement device enabled accurate measurement of much higher pressures than existing measurement devices.
What is the English meaning of Bourdon?
Definition of bourdon 1 : burden entry 3 sense 1. 2a : a drone bass (as in a bagpipe or a hurdy-gurdy) b : a pipe-organ stop of a droning or buzzing quality usually of 16-foot pitch. c : the lowest bell (as in a carillon) in a ring of bells.
What is the function of Bourdon gauge?
Instrumentation System Elements. The Bourdon tube is an almost rectangular or elliptical cross-section tube made from materials such as stainless steel or phosphor bronze.
How does a bourdon tube gauge work?
Chemical processing plant
What pressure does the Bourdon gauge measure?
Absolute pressure is zero-referenced against a perfect vacuum,using an absolute scale,so it is equal to gauge pressure plus atmospheric pressure.
What is the source of error in a Bourdon gauge?
The existence of one potentially major source of error in Bourdon tube pressure measurement has not been widely documented, and few manufacturers of Bourdon tubes make any attempt to warn users of their products appropriately. The problem is concerned with the relationship between the fluid being measured and the fluid used for calibration.
