About - Industrial Vibration Sensors
When the object makes regular reciprocating motion in the equilibrium position, it is called mechanical vibration. There will be mechanical vibration when industrial equipment is running. When the mechanical equipment is working, the vibration signal can judge the status of the equipment, and different signals represent different equipment information. The industrial vibration sensors are used to measure fluctuating acceleration or velocity or for normal vibration measurements. Workers use vibration sensors to predict machine maintenance to reduce overall costs and improve machine performance.
When equipment components or the environment change. Its welding points and connectors are easy to loosen and even cause permanent damage. If it is not discovered in time and the mechanical equipment continues to operate under such conditions, the equipment will vibrate abnormally and fail. Our industrial vibration sensors can continuously measure equipment vibration, helping technicians to do preventive maintenance work in time and avoid major failures. The vibration and temperature sensor has many output signals, the more commonly used ones are analog output , RS485 output and LoRa output.
Our temperature and vibration sensors with RS485 or LoRa outputs can measure the speed of the X, Y, and Z axes. Measure the vibration velocity, vibration displacement and temperature. If the vibration acceleration is to be measured in the use environment, it is also possible. For our temperature vibration sensor, the vibration speed range is generally 0-50mm/s. If the measuring equipment does not match this range, you can choose any other range.
Types and Datasheets
Modbus vibration sensor
The RS485 vibration sensors use a 10-30V DC wide voltage power supply. Suitable for dry, humid, noisy, and other environments, waterproof and dustproof. The measurement data is transmitted through the signal line, free from environmental interference, safe and stable. The Modbus vibration sensor can measure a single axis or three axes. The transmission distance is long, up to 2000 meters, which can realize remote monitoring. If there are few measuring points, you can choose a network collector, which can not only reduce the cost, but also meet your own needs.
