| titleOfInvention | Online ion sensor for drilling fluid |
| abstract | The utility model relates to an online ion sensor of drilling fluid contains: a protective housing; the composite electrode sensor is arranged in the protective shell, comprises an ion sensitive membrane electrode and a reference electrode which are fixedly arranged at one end part of the composite electrode sensor, and respectively measures and outputs the electrode electromotive force in the drilling fluid; and the transmitter is connected with the ion sensitive membrane electrode through a first signal outgoing line and connected with the reference electrode through a second signal outgoing line, and the voltage difference between the first signal outgoing line and the second signal outgoing line is acquired and measured. The utility model discloses simple structure, the stable performance, simple to operate, low cost, long service life realizes at the drilling scene to the long-time continuous on-line measurement of last drilling fluid mesoion concentration. |
