Vibration detector is similar to vibration sensor and they are both tools used for vibration measurement and detection. But its precision is higher than vibration sensor and its monitoring objects are more important. For example, machine tool with high precision mainly uses vibration detector to detect its vibration state.
1. Principle of vibration detector
The principle of vibration detector has many similarities with vibration sensor’s. They both collect mechanical quantity of the vibration and transform it into current by system processing and then recognize. When detecting, it will judge the current received by the system. If the current is over certain range, vibration detector will raise the alarm.
2. Functions of vibration detector
Vibration detector can have a 24-hour continuous detection of mechanical devices. It will measure the vibration frequency of the mechanical devices at all times. When the vibration frequency is exceptional, it will immediately raise the alarm and prompt users. The application of vibration detector can help users reduce losses caused by exceptional vibrations minimally.
The vibration detector has high sensitivity and wide detection range. It can detect any vibration waveform in real time and collect vibration data occurred in all directions. Vibration detector with high performance can achieve to collect vibration data in three different directions in one-thousandth of a second.
3. Usage of the YT-SHK-A vibration detector
Vibration detector has high measurement sensitivity and good anti-jamming capability as well as higher reliability than vibration sensor. Therefore, it is widely used for vibration detection of mechanical devices such as precision machine tool and security monitoring of ATM, vaults, motor vehicles and walls and windows of warehouse.
Vibration detector is strong and durable with compact structure and can work independently. It is specially designed to protect mechanical devices from imbalance, eccentric errors and looseness as well as bearing worn. It can be applied to detect the vibration level which can detect the failures in advance and thus make the arrangement of preventive maintenance plan easier.
Vibration detector can be directly fixed on the measurement point of the protected machine. Due to its small cubage, it can be installed almost everywhere.
It is most suitable for protecting exhaust fans, blowers, crushers, compressors, coolers, mixers, cash dispensers, vaults, warehouses, fence walls, glasses, large motors, transmissions, turbines, conveyors, pumps, centrifuges, vibratory conveyors and most reciprocating machines.
