SPRn transducers
|
|
For many liquid mixtures, the speed of sound is directly proportional to the concentration of the components. Therefore, sound velocity measurement can often be used for concentration measurement of 2-component mixtures. The online sound velocity transducers from Anton Paar continuously check the quality and specifications of liquids during production. The transducers use piezo technology for measuring the sound velocity and transmit measuring signals to the evaluation unit mPDS 1100 or mPDS 2000V3 for automatic conversion into Original Extract, % H2SO4 and many other concentration readings.

STR transmitters
|
|
STR transmitters use the same measuring pinciple, but have an integrated circuit board for temperature compensation and simple concentration calculation. The measuring result is provided as a 4 to 20mA current signal. A separate mPDS evaluation unit is not required. The STR Transmitters can also be integrated into a Profibus network (PA or DP).

Efficient production
|
|
The sensors have a very short response time, allowing you to react immediately to the results and save money by preventing out-of-spec product.

Wetted parts
|
|
Different materials are available. There are hygienic 3A models and intrinsically safe "I" models. All our sensors are designed for rough conditions in the process environment. There are no moving parts and the complete system is CIP compatible.
