Answer / ghanshyam khatri

two types one contect type onether is non contect type
contect type is eddycurrent based and noncontect type is piezo electric. in non contect type we have to set gap voltage and output is volts and piezo type only output is 4 -20mA

Answer / faiyaz ahmad

vibration sensor is device which is used to measure the gap voltage between the rotating shaft and probe working principle of vibration sensor is eddy current and there are four types of vibration sensor.
Axial vibration
Radial vibration
seismic vibration
vibration switch
Axial vibration is installed in 180 degree and radial vibration is used in 45 degree both are device which is used to gap voltage.

Answer / vinod

There are two types of vibration measurement Technics one is contact type and another one is non contact type. non contact works on eddy current principle mainly used in turbine section contact type is used in feed pumps and id fans etc works on piezoelectric principle .

Answer / nabeel

Eddy current is the principle and there are mainly two types and the are 5 meter system and 9 meter system.

if we open the inlet of an air regulator ,how it will affect the out put of regulator? (out put of regulator is using to operate an on-off valve.it is an air to open valve,and valve is in open position.my doubt is air regulator will hold the valve in open or not,if there is no consumption or leak in regulator out put side ,we only loose the input pressure.)
