Mud Density Sensor | Differential Pressure, 0.96-3.0 g/cm³ | CNPS

The sensor measures drilling fluid density continuously using a differential pressure design: it captures precise pressure readings within fixed depth intervals of the fluid column and converts the differential pressure into mud weight data. The measurement runs automatically and in real time, eliminating the delay caused by manual sampling, and supports water-based, oil-based, and cement slurries.

• Density range 0.96 - 3.0 g/cm³, configurable by application — Covers water-based, oil-based, and cement slurries with application-specific configuration.
• Accuracy as high as ±0.5% FS — Trustworthy mud weight data for drilling decisions.
• Stainless steel casing with IP67 protection — Operates reliably in high-pressure, high-temperature, and corrosive drilling environments.
• Outputs: 4-20 mA, HART, or wireless signal transmission — Flexible integration options for any mud logging setup, wired or wireless.
• Compact, easy-to-install design — Quick installation on the mud logging instrument without major modifications.
• Low maintenance cost — Sturdy structure minimizes the frequency of cleaning and calibration.
• Digital interface with clear output — Simplifies interpretation of on-site data for rig personnel.
• Explosion-proof rated design (IP67, as documented) — Suitable for hazardous drilling areas according to the source documentation.

Summary: The mud density sensor uses a differential pressure design: it captures precise pressure readings within fixed depth intervals of the drilling fluid column and converts the differential pressure into mud weight (density) data in real time.
