Wireless conductivity sensor for mud logging unit

Wireless conductivity sensor for mud logging unit Wireless conductivity sensor is mainly to monitor the conductivity change of drilling fluid.


Measuring the conductivity of drilling fluid is mainly to monitor the conductivity change of drilling fluid, judge whether there is formation fluid entering according to the change trend, and judge the property of formation fluid immersed in drilling fluid.


Measuring range: (0~1000) mS/cm

Accuracy: 2%

FS Supply voltage: 3.5-5VDC

Output signal: 0.5-2.5V

Working temperature: -20~70°C

Protection level: IP67


Conductivity sensor is mainly used to measure the conductivity value of liquid and mud. The conductivity sensor is characterized by reading the conductivity value directly from the display screen and having 4 ~ 20mA analog signal output. Two – wire power supply, easy to operate. This product can be used in explosion – proof situation.


The sensor consists of a conductivity probe and a conductivity converter. The conductivity probe consists of two parallel magnetic coils, which are composed of primary and secondary coils. The outer casing is made of high temperature resistant, acid and alkali resistant and wear resistant insulation. The primary coil is fed with a sinusoidal excitation signal of constant amplitude and frequency. As the conductivity of the drilling fluid changes, the induced signal of the secondary coil also changes accordingly. The conductivity converter performs amplification and filtering on the induced signal to obtain a standard output, thereby completing the measurement of the conductivity of the drilling fluid.


All sensors either are EX type or are intrinsically safe. Zone barriers are installed in the Unit. Using well-known brand products at home and abroad, the sensors of mud logging unit have the advantage of technical and performance indicators. At the same time, the service life is long.

1.Why do you choose our company?

We are trading company, founded a perfect oil and gas equipment product supply chain. We have worked in the oil industry for about 10 years(follow ISO9001 standard).We will checked our mill every months to make sure their quality. The after-service are charged by ourselves.So we can reply any problem within 24 hours.

2. How can you guanranty your quality?

Every time we will inspect our factories first. This inspect will include the persons, the present products, their scale etc. If everything is ok, we will start to cooperate. During cooperation, we will go to the factories to test the products to guanranty the products has good quality. If it doesn’t meet our requirement, the goods will be refused.

3. Do you have price advantage?

For us, the quality is our first consideration. And the second consideration is the price. We couldn’t say we have the lower price, because of quality issue. We need to say we have the best price.
