PT100, inspection devices, and the M400 data acquisition management software – please help to take a look, thanks
Thread Content
I’m currently using an inspection instrument and PT100 sensors for measurements. After connecting them, some of them display values properly while others do not – it seems like there might be poor contact issues, but all the components are new. I’m not sure what’s causing this problem. Sometimes the readings are fine, but when I use a different connector, things stop working properly. The inspection instrument used is an XSLE high-precision model, and the PT100 sensors are of grade A, four-wire type. I’m also using the M400 data acquisition software, which only displays the temperatures of four channels; it doesn’t show the multiple channels as specified in the manual. . . Dear experts, please help and give some advice! !
A standard resistance box can be used to input signals into the inspector to determine the quality of the instrument!
Hehe, our Kunlun instruments and M400 data acquisition software
Is poor contact caused by the wiring terminals not being connected properly? Is the M400 data acquisition software 16-channel or how many channels? Is it because you have set the number of channels displayed in the real-time data to 4?
Check if there is a problem with the PT100
Let me explain more in detail. There are still problems, and I’m not sure if there are any experts in this field based in Tianjin Or tell me where to look for it; I hope I can visit there if I have time. Thank you. The basic situation is as follows: at room temperature, the value remains relatively stable, but when measuring other temperatures, it doesn’t work well. For example, with an ice-water mixture, the temperature reading stays around 1 degree, and this value keeps changing by about 1 degree. When it comes to boiling water, the temperature variation is even greater, around 3 degrees, and the measured value shows around 95 degrees. The differences between multiple thermistors are also unstable. Thank you! ~~~
