In modern society, various machines are involved in our daily life all the time and assume an important role in our surroundings. Bearings, motors, pump bodies, etc. have also become the key existence in industrial civilization, and their temperature and status affect the health and efficiency of the whole industrial automation system operation.
For a long time, sensor technology has been the core technology in the field of monitoring, with the increase of our industrial automation market demand and the development of sensor technology, the measurement of temperature and vibration also from the split to the composite. Temperature and vibration sensor is a composite vibration collector integrating embedded technology, temperature sensor technology, and vibration sensor technology, which can collect data from three axes of machinery at the same time, and is suitable for online measurement of temperature and vibration of rotating class equipment such as motors, generators, reducers, fans, air compressors, centrifuges, and submersible pumps. As a monitoring tool, since it can be used in so many places, there must be many different ways of data transmission, next, we will take stock of several transmission methods commonly used in the market for temperature and vibration sensors.
The first one: LoRa wireless transmission
LoRa temperature and vibration sensor, also called LoRa temperature and vibration collector, can be used with LoRa gateway and environmental monitoring platform to form LoRa temperature and vibration monitoring system. The LoRa gateway will transmit the obtained parameters such as machine surface temperature and vibration speed to the backend server through 4G, and the relevant personnel can log in to the environment monitoring platform on their cell phones or computers to view the changes of machine surface temperature, vibration speed, vibration displacement and other parameters, so as to fully grasp the health status of machinery operation.
LoRa temperature and vibration collector uses wireless spread spectrum communication technology, which can achieve the purpose of wiring-free during the whole process of information transmission, suitable for the environment where the arrangement of cables is inconvenient; built-in 19000mAh large-capacity battery, coupled with the low power consumption, the service life can even reach 8 years, and when the battery power is exhausted, it can also continue to use by replacing the lithium sub-battery, which is simple and convenient; the shell 304 Stainless steel design, protection level of IP67, and a LoRa gateway can be used with multiple measurement points.
Here is a point of clarification: LoRa gateway has 4G communication, ETH communication and 485 communication methods of uploading, which can be selected according to the use environment when using.
The second type: 485 transmission method
485 temperature and vibration sensor, also called 485 temperature and vibration transmitter, can be used with environmental monitoring host/network collector and environmental monitoring platform to form a 485 temperature and vibration monitoring system. 485 temperature and vibration transmitter can transmit the collected machine surface temperature and three-axis data to the environmental monitoring host/network collector through RS-485 signal data, and the environmental monitoring host/network collector will transmit the obtained machine surface temperature and three-axis data to the environmental monitoring host/network collector. surface temperature and three-axis data to the environmental monitoring platform. The relevant personnel can view the real-time data on the computer and master the health condition of the machine when it is running.
The 485 temperature and vibration transmitter is powered by a wide voltage supply of 10-30V DC. The shell is made of stainless steel with IP67 protection level, which is suitable for dry, humid and noisy environment, waterproof and dustproof; the signal output is not disturbed by the surrounding environment, safe and stable; the transmission distance is far, which can reach 2000 meters, meeting the use requirements of most scenes.
Note: If there are fewer measurement points you can choose a network collector, which can reduce costs and also meet your needs.
The third type: analog output
Analog type temperature and vibration sensor, also known as analog type temperature and vibration transmitter, it can convert the vibration signal in the machinery to analog output, and through the PLC data module to collect and upload the vibration information of each measurement point to the upper computer, the relevant personnel can monitor the vibration speed, displacement and temperature change of each measurement point in real time in the upper computer.
Analog type temperature and vibration transmitter is also 10-30V DC wide voltage power supply, built-in MEMS chip, high measurement accuracy; IP67 protection level, stainless steel housing material, internal potting techniques allow it to have a lot of room for play.
There are various ways to install the temperature vibration sensor, such as magnetic suction type, threaded type, and some scenarios will also use the adhesive type. In the increasingly developed industrial technology, temperature and vibration sensors carry an important mission to help many fields to solve the potential hidden dangers of machinery difficult for ordinary people to detect, reduce the cost of large-scale maintenance of machinery, effectively extending the use of machinery time, become an important part of industrial machinery monitoring.
