Capacitance Level transmitters

Capacitance level transmitters provide continuous level measurement by detecting changes in electrical capacitance between a probe and the vessel wall. As the level of liquid, slurry, or bulk material rises, the dielectric properties around the probe change, resulting in a measurable variation in capacitance that is converted into a stable output signal (typically 4–20 mA). This proven measurement principle enables reliable level monitoring across a wide range of process conditions, including applications where density, temperature, or composition may vary.

Widely used in industries such as water and wastewater, chemical processing, food production, and bulk solids handling, capacitance level transmitters are valued for their robustness, fast response, and ability to measure liquids, powders, and interface levels. With no moving parts and suitability for harsh environments, they offer a low-maintenance and cost-effective solution for accurate level control in both standard and challenging industrial applications.

Measurement Solutions supports capacitance level measurement technologies from established manufacturers such as Drexelbrook, known for reliable performance in challenging process environments.

Why Drexelbrook??

Drexelbrook excels at RF Capacitance and RF admittance based measurements because of their patented Cote-Shield technology. Cote-Shield not only inhibits the effects of coatings from the process but also provides an unmatched measurement stability which permits the devices to be used on many processes other manufactures struggle to measure.

Superior reliability is synonymous with Drexelbrook’s products. Many users are suprised to find on an old Drexelbrook RF instrument hidden away in the corner of the plant having not needed any attention in 20+ years of reliable service. That’s how tough they are!!
