Pressure gauges with bourdon tube: Bourdon tubes are circular curved tubes of oval cross-section. The to be measured pressure acts on the inside of the tube, causing the oval cross section of the circular shape approaches. The curvature of the spring tube creates ring stresses, which are the spring bend. The unbalanced spring end performs a movement that is a measure of the pressure.

 

For pressures up to 40 bar generally circularly curved springs with a winding angle used by 270 °, for higher pressures springs with several turns in helical form.

 

Bourdon tubes have a relatively low restoring force. Therefore, with optional equipment such for example, towing pointers, border signalers or resistance transmitters whose influence to be considered on the ad.

 

Bourdon tubes measuring devices can only limited by supporting the measuring element in a Limit pressure value to be protected against overload. Bourdon tube pressure gauges are used for Measuring ranges from 0.6 bar to 4000 bar are mostly used in classes 0.6 to 2.5.

 

The influence of temperature change on the display is mainly due to the temperature gradient the modulus of elasticity of the Bourdon tube determined. The temperature-related error depending on the material between 0.3% and 0.4% per 10 K.
