Electric Torque Sensor Mud Recording Sensor

Electric Torque Sensor Mud Recording Sensor Electric torque sensor is a sensor to obtain the torque parameters of the rotary table by testing the power supply current of the drive motor.


The sensor is designed to measure the torque of the rotary table. Therefore, the working status of the drilling rig and bit can also be reflected. Based on the principle of Hall effect, when the torque changes, the supply electric current also changes, which is used to drive the rotary table.


Power source: +15V ~ 30V DC (recommended +24V DC)

Measuring range: 0 ~ 1000A

Output current: 4 ~ 20mA DC

Measurement accuracy: ±1%FS

Frequency response: 0 ~ 1000Hz

Environmental conditions: operating temperature -40℃ ~ +85℃


The SMC-ETQ-B11 AC/DC torque sensor adopts a closed-loop structure. According to the principle of Hall effect, the value of the measured current is proportional to the output current of the Hall effect sensor, that is to say, when the measured current varies from 0 to 1000A, the output current of the sensor varies in the range of 4 ~ 20mA, and is in direct proportion.


Open the sensor clamp, wrap the measured wire with plastic foam, and adjust the thickness of the winding, so that the measured wire can be fixed in the round hole after closing the clamp, without being shaken. Pay particular attention to the direction of current during installation. The side with the regulation port is the direction of current input, and the side without regulation port is the direction of current output. Do not install in the wrong direction.

4.2 Wiring of the V+ sensor (yellow): +24V DC

VO (blue): 4-20ma output

OV (brown): mass


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

1. Why choose our company?

We are a trading company, based on a perfect supply chain of oil and gas equipment products. We have been working in the oil industry for about 10 years (we follow ISO9001) and we check our factories every month to ensure their quality. After-sales service is taken care of by ourselves, allowing us to respond to any problems within 24 hours.

2. How can you guarantee your quality?

Every time, we inspect our factories first. This inspection will include people, current products, their scale, etc. If everything goes well, we will start to cooperate. During the cooperation, we will go to factories to test the products to ensure the good quality of the products. If it does not meet our requirements, the merchandise will be refused.

3. Do you have a price advantage?

For us, quality is our first concern. And the second consideration is price. We can’t say we have the lowest price, because of the quality problem. We have to say we have the best price.

4. How long have you been exporting?

Our salespeople have 8-10 years experience in international trade. They understand every step of exporting and provide good service to each of our customers.
