Problems with Rongcheng Coast capacitive level gauges
Thread Content
The on-site gauge head shows 1.105 m, the measured output current is 13.8 mA, the DCS remote display shows 0.9 m, and the range is 1.5 m. What is the reason for the discrepancy between the remote transmission and the on-site display? The model number of the header is RC-139; I’ve never used this type of display panel and don’t know how to operate it :( Could anyone who knows how to use this smart header share its manual with me?
“The on-site gauge head shows 1.105 m, the measured output current is 13.8 mA, the DCS remote display shows 0.9 m, and the range is 1.5 m. ” The output current value matches the DCS display value, but the reading on the gauge does not match the output current value. In such a case, it’s either the gauge is malfunctioning or the output board is faulty; adjustments need to be made to correct this. I live in a remote area without any seas or coasts, and I don’t have the manual. {:2_36:}
I guess so too. Now we need to calibrate the displays at 4mA and 20mA. Can a capacitive level gauge be calibrated using water instead of the actual process medium?
When installing or calibrating a level transmitter, if it is not in a metal container, the transmitter’s casing must be connected to the bottom of the container using a wire.
