The new L-Dens 7000 density sensor series
Highly precise and easy to integrate
L-Dens 7400/L-Dens 7500
The new L-Dens 7000 series – the new generation of Anton Paar’s process density sensors with a tube size of 6.3 mm (inner diameter) – is a result of more than 35 years of essential practical experience. This all-in-one solution combines the highest accuracy, compact and robust design, and easy integration, which makes it best-in-class for precise concentration measurement. There are two types: 4-digit accuracy L-Dens 7400 and 5-digit accuracy L-Dens 7500. Density values are directly calculated by the sensor electronics.

The design of the oscillating U-tube follows the requirements of hygienic applications. Both, L-Dens 7400 and L-Dens 7500, have one-piece oscillating tubes (L-Dens 7400: U-shaped tube; L-Dens 7500: W-shaped tube). The L-Dens 7000 series uses digital signal processing and can be equipped with the new Pico 3000 transmitter and Pico 3000 HMI.

Highest precision – reliable measurement under changing process conditions
The L-Dens 7000 density sensor series measures with the highest precision and an outstanding accuracy of up to 5 x 10-5 g/cm³.

The L-Dens 7000 series provides:

Powerful digital signal processing
Integrated high-precision temperature sensors
A hermetically sealed U-tube to withstand humidity condensations
The highest accuracy in temperature and optional pressure measurement is the basis for compensating unstable process conditions. Thus, changing process and environmental conditions have a negligible effect on the measurement. This keeps the production flexible to react to market or consumer demands.
