Monitoring the shaft speed of rotating machinery is an indispensable part of closed-loop control. The sudden change of speed is also an important parameter to reflect the running condition of the machine, such as rotor grinding, misalignment, stress and bearing damage in the rotor system will be shown from the process of speed change with time, so monitoring shaft speed can be warned in advance to avoid machine damage and unplanned production. VB-Z440G intelligent tachometer can reliably measure shaft speed, suitable for various types of rotating machinery. It can be equipped with a variety of speed sensors (such as magnetoelectric sensor, Hall sensor, etc.).
· Input power protection function.
· You can set alarm parameters, range, relay delay and other parameters by pressing the button.
· The set parameters will not be lost after power loss.
· Sensor break detection, sensor break, block relay output, OK light out.
· The speed signal can receive the reluctance sensor and eddy current sensor signal.
· Lock the relay output within 10 seconds after power-on.
