Product Details

1 Product Overview

RS485 vibration sensor:

The DAQ-GP-VT485 vibration velocity (acceleration) sensor adopts a stainless steel housing design. Internally it mainly consists of a power module, a vibration acquisition unit, and a data processing and transmission module. After the device vibration value is acquired and processed by the sensor, it is transmitted to the receiving terminal via 485 communication for centralized monitoring.

LoRa wireless vibration sensor:

The DAQ-LP-VTLORA wireless vibration velocity (acceleration) sensor adopts a stainless steel housing design. Internally it mainly consists of a battery, a vibration acquisition unit, and a data processing and transmission module. After the device vibration value is acquired and processed by the sensor, it is transmitted to the wireless receiving terminal via LoRa wireless communication for centralized monitoring. Each sensor has a unique communication ID.

It can be applied to online measurement of vibration velocity, acceleration and temperature of motor equipment, reducers, fans, generators, air compressors, centrifuges and water pumps in many fields such as coal mines, chemicals, metallurgy, electric power, building materials, automobiles and machinery manufacturing.
