Asking for advice on flow meter pulse signal transmission problem
Thread Content
Dear experts, what type of cable should be used for remote transmission of the pulse signal of the flow meter (cable type? * ? ) will be better
This is more difficult. Unmodulated rectangular wave pulse signals are easily distorted during transmission.
The most embarrassing thing is that I participated in a project. There was a mass flow meter with three signals.: AI (density), AI (temperature), PI (flow). At that time, I asked the master who led me, and the cables were all made of 1×2×1.5mm2, copper-core fluoroplastic insulated flame-retardant PVC sheathed copper-plastic composite tape wrapped and shielded DCS soft cable. I am a newbie, please give me some advice from experienced netizens.……
The cables are all made of 1×2×1.5mm2, copper core fluorine plastic insulated flame retardant PVC sheathed copper plastic composite tape wrapped shielded DCS soft cable. I would also like to ask if the above cable can be used for a solenoid valve powered by tens of watts of 220V AC?
An ordinary cable will do, KVVP 1×2×1.5
The solenoid valve cable is 1×2×2.0mm2
We use computer cable DJYVP 2* 1.5
Reply to 5# liuei Is it a solenoid valve with tens of watts of 220V AC power supply? You can use this ordinary cable
Reply 8# lant Yes, it may be thicker (more than 2.5) if the distance is very far, and the pressure drop needs to be calculated!
passing by, learning* For a moment, we don’t use pulse signals and don’t know how to use them. Is pulse signal better than MA signal?
There will be no error when the pulse signal is used for measurement, but there will be a little cumulative error when using the mA signal!
