Wireless temperature meter
Thread Content
It’s a rotating device driven by a set of high-power motors, equipped with five sensors for wireless temperature monitoring. The temperature values shown are sometimes on the high side, and there are significant fluctuations in these values from time to time. What could be the reason? Experts, please analyze it for me
It could be interference; electromagnetic interference generated by the motor operation is quite significant. Additionally, factors such as whether the equipment is properly grounded, the shielding of the electrical control cabinet, and power supply interference can all cause temperature fluctuations
It might be interference; the grounding was redone, and it’s been a few days since that was done, but now it’s not stable again
Is the temperature of the motor transmitted via a wireless signal pathway?
Rotating equipment, temperature on the equipment
Regarding the rotating equipment you mentioned, which part of it do you mean by wireless? Wireless temperature change?
The wireless temperature thermistor is installed on the equipment; there is a signal collector on site that uses Modbus to transmit the signals to the DCS
? Where can I find wireless temperature thermistors? Is the connection from the temperature transmitter to the signal collector wireless?
It seems you need to see the image to understand; pictures speak louder than words. I’m not clear what you’re referring to
This is the method used for temperature measurement in rotary kilns
For rotary kilns, I think it’s thermocouples; thermocouples are prone to interference.
