Pressure Measurement on Railway Tank Wagons
Bourdon tube pressure gauges for pressure monitoring on tank wagons for powdery goods
Deutsche Bahn AG, for manufacturers of rail cars, shipping companies (e.g. chemical industry)
Tank wagons that transport powdery goods belong to the special purpose wagons. These are normally equipped with a pressure gauge for pressure monitoring.
The Problem
Tank wagons that transport powdery goods have to be monitored on varying pressure ratios. During test operation (24 h) the pressure range is 1.0 bar. During transport, the pressure must be 0.5 bar. Unloading takes place at a pressure of 2.5 bar, which must not be exceeded.
Our Solution
In order to be able to monitor these values accurately, we have “spread” our pressure gauge. This means, in a range from 0 – 1.4 bar over 120°, we are able to read the values precisely. The unloading pressure is 2.5 bar. A red mark indicates the unloading pressure. This pressure must not be exceeded.
