Description
Adash America A3900 – 1 Channel Online Condition Monitoring with Display
- Machine monitoring systems
- Simultaneous measurement of velocity (mm/s, ips) and acceleration (g)
- Relay for indication of exceeding the predefined vibration limits (ALARM, ALERT)
- Measured quantities are exported as output current loops 4-20 mA
- Simple connection to control systems (PLC)
The Adash 3900-II Demo is designed for simple promotion of A3900 features. It content wide range power supply, which enables to work with voltage from 100V to 230V.
Also the relay is installed, which switch on or of the output power in relation to vibration level. When vibration level exceeds the vibration limit ( set by user), the power output is switched off. When the vibration level decreases under limit, then the power output is switched on.
The simple machine (e.g. grinder) is often used for demonstration purposes. The exceeding of limit switches off the machine. It is important, that the machine has to have the special circuit breaker cold Magnetic Safety Switch. These switches automatically shut down when the power unexpectedly goes off. When the electricity comes back on, the equipment will not start up until you press the start button.
When the powering is interrupted (vibration higher then limit), then this breaker has to switch off itself and must be switched on manually. If the breaker has not this feature, then the A3900 continuously switch off and switch on the machine. That is why the vibration level decreases under limit, when the machine is switched off.
Scheme
Current loop 4-20mA output is powered from internal 24V power. It means, you can use standard simple voltmeter for display of current value.
