MUD DENSITY SENSOR
The CNPS-ML-B11 drilling fluid density sensor is a single crystal silicon resonant density sensor for measuring the density of drilling fluid. The sensor adopts EJA118W, a diaphragm-sealed differential pressure transmitter imported from Japan, which has the advantages of high measurement accuracy, stable performance, and good repeatability. The outer mounting bracket is made of stainless steel, and it is corrosion-resistant and has a long service life. The base is detachably attached with a long rod, which can be adjusted according to the depth of the mud. It is an important sensor for oil and gas exploration work, which can be applied to various harsh environments such as oilfields.
|1||supply voltage||+17V ~ 42V DC(Recommend +24V DC)|
|3||measure scale||0.96 ~ 2.76g/cm3(Can be set according to user needs)|
|6||working temperature||-40℃ ~ +85℃|
|7||Relative humidity||5 ~ 95%RH|
The distance between the two pressure diaphragm of the CNPS-ML-B11 drilling fluid density sensor is 45cm and 60cm, the outlet density sensor is 45cm, and the entrance density sensor is 60cm.
According to the needs of measurement, we choose to install sensors on the drilling fluid inlet and drilling fluid outlet respectively. When drilling fluid level fluctuates, the upper and lower flanges must be immersed in the mud to keep it upright and not tilted, otherwise it will affect the accuracy of measurement. The transmitter changer shall be above the mud level and not immersed in mud.
