Wireless casing pressure sensor for mud logging unit

Wireless casing pressure sensor for mud logging unit Pressure sensor is a kind of device that converts non electric quantity into electric signal.


There are many kinds of pressure sensors, such as resistance strain gauge pressure sensor, semiconductor strain gauge pressure sensor, piezoresistive pressure sensor, inductive pressure sensor, capacitive pressure sensor, resonant pressure sensor and capacitive acceleration sensor. The sensor is a piezoresistive pressure sensor.



Working voltage: 3.3VDC

Output: 0.5~2.5VDC voltage signal

Measuring range: 0-110 MPa

Accuracy: ≤1%F·S

Working temperature: -20~70°C

Protection level: IP67



This system is mainly used in oil drilling exploration and development, and it is used together with integrated logging instrument. It can completely replace wired sensors for logging construction, and make up for the shortage of installation, maintenance and construction of wired sensor acquisition system.



The casing pressure sensor is mounted on the throttle manifold. The standpipe pressure sensor and casing pressure sensor is directly in contact with the mud through the head-to-head conversion unit provided with the instrument. Due to the high pressure during normal operation, when installing the size head and pressure sensor on the riser/sleeve, be sure to pay attention to the tightening and sealing of the installation. To avoid foreign matter from the lead end, the cable lead-out of the sensor should face down.



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.
