Centec High Precision Sensors

Search filters:

Centec sensors are applied in laboratory and process environments. They ensure that products are produced to consistently high standards and that processes run extremely efficiently with the least consumption of energy and raw materials.

Our portfolio covers the following measurements (click on product for more information):

  • OXYTRANS – O2 in liquids and gases

  • CARBOTEC – dissolved CO2 in liquids

  • RHOTEC – density of liquids and fat content

  • SONATEC – sound velocity in liquids


The measurement of density or sound velocity allows the concentration of a media such as acid or caustic to be displayed. In three component liquids both density and sound velocity need to be measured.

Sensor Innovations

External Display

Aiming for increased user-friendliness, the external display is the perfect solution for installations that are difficult to access. Available for OXYTRANS, RHOTEC and SONATEC. With two 4 mA - 20 mA outputs. Cable length between sensor head and display up to 10 meters.


Vortex Injector

Gases such as O2, CO2 and N2 are injected into liquids as very fine homogeneous bubbles and quickly dissolve into solution. The high efficiency of the system reduces the consumption of gases d to a minimum.



Retractable Unit for O2 Sensor

For continuous measurement of the O2 content in liquids and gases. The sensor can easily be drawn back without stopping the system, e. g. during sterilization of the plant. Manual and pneumatic version.
