A chameleon in the vacuum

Smartline vacuum transducers can adapt themselves exactly to predominant ambient condi-tions of your vacuum application. Practically speaking: The 0 – 10 V output signal of the transmitters is scalable in accordance with the desired characteristic curve.

This works by means of a simple software command, which is sent via the digital RS485 in-terface of the gauge, and can be implemented at delivery ex works or simply by the user himself. It is therefore possible to scale, for example, the measuring range of a Pirani to 1.5 – 8.5 V, 1 – 9 V or to 2 – 9 V.

If vacuum transducers are to be replaced in existing applications, reprogramming of the system control can consequently be omitted. Furthermore, relevant operating pressure ranges can be zoomed out, i.e. pressure ranges which are important for the process sequence can be output at the entire available signal range 0 – 10 V.

Smartline transducers measure from 1000 mbar to 5e-10 mbar and are optionally available with a back-lit LCD display. Thanks to modern combination sensors they are able to simultaneously record different pressure ranges such as fine and high vacuum with high precision and reliably steer your process pressure to the target.
