Digital pressure gauge common fault analysis
2014-07-02 Reads : 22
Digital manometer common fault is inaccurate data appears, mainly in the following five reasons: 1, the effect of temperature are not fitted with water trap, high-temperature steam or hot liquid directly into the spring tube, except under pressure, since the temperature The expansion and contraction of the spring-generating elongation, resulting in increase of the spring action, the error becomes large. 2, the impact of vibration is measured as a gas, liquid or measured body vibration; a vibration gauge internal organization. The results of vibration makes the gauge gear wear deformation, gossamer disorders, pointer loose, bearing damage, etc., resulting in the loss of accuracy of the gauge, or even damaged. Digital pressure gauge Troubleshooting two digital pressure gauge pointer does not refer to the zero position. 3, the spring bends loses its elasticity (straight). 4, gossamer loss of elasticity and loss. 5, three cocks channels, pressure gauges and even clogged pipe or water trap, making the pointer bent or stuck.
