Process Density Sensor: L-Dens
Anton Paar has more than 40 years of experience in process density measurement. So the L-Dens oscillating U-tube density sensor is more than just a cutting-edge instrument, it’s a decades-long story of core, real-world experience. This all-in-one solution combines pin-point accuracy, a compact, robust design, and easy integration – making L-Dens best-in-class for precise density and concentration measurement across a whole spectrum of industries and applications.
Real-time, top-precision concentration measurement
The L-Dens process density sensors come with 4-digit accuracy (L-Dens 7300 Petro, L-Dens 7400) and 5-digit accuracy (L-Dens 7500), and the integrated, high-precision temperature measurement (pressure measurement optional) lets you follow process changes in real-time. The density sensors cover a wide range of applications and industry requirements across these sectors:
High resistance, flexible installation, stable values, low costs
The L-Dens density sensors are resistant to aggressive media – wetted parts comprise a variety of different materials. Whether you’re looking for inline, bypass, or tank installation, Anton Paar offers a comprehensive selection of adapter solutions across all industries. We also offer customized solutions, too.
L-Dens 7000 is also available in an explosion-proof version specially designed for the measurement of flammable liquids in hazardous environments. The sensors can also be combined with the new Inline Pump 300 Ex d to guarantee high-precision measurement in tanks or under highly fluctuating process conditions.
Anton Paar’s L-Dens series:
Can be used in hazardous environments
Can be exposed to extremely aggressive chemicals
Can be installed as follows: inline, bypass, tank
Pre-configured – no maintenance or consumables
The L-Dens 7000 density sensors require neither maintenance nor consumables. Preconfigured and adjusted in the factory, they come with the right sensor setup and application formulas, tailored to your needs. Start up quickly – and start measuring right away.
We tell you how best to measure your sample
Don’t know how best to measure the concentration of your liquid? We’ll tell you. Anton Paar has a comprehensive database as well as application know-how from across industries (e.g., chemicals, beverages, petroleum). In our in-house laboratory, we measure customer-specific samples and develop a tailored formula just for you. We suggest the measuring method (density, sound velocity, or refractive index) that’s most suitable for your sample, desired concentration, and temperature range.
