TWO-WIRE VIBRATION TRANSMITTER
Two-wire vibration transmitters are 'loop-powered' devices that provide a continuous 4-20 ma signal proportion to the level of machine vibration calibrated in units of acceleration, velocity or displacement. These rugged, hermetically-sealed transmitters provide continuous machine condition signals for remote alarming, display or trending. Two-wire vibration transmitters are first broken down into two catagories..... top exit electrical connection transmitters and side exit electrical connection transmitters. While both styles offer equial measurement performance, these two configurations allow the customer to choose which style will best suit his installation requirements.
TOP EXIT Vibration Transmitters (A=Acceleration V=Velocity D=Displacement)
