High-precision measuring operations using inexpensive standard sensors -

Although special-purpose sensors with a non-

linear output can usually be connected to e

xisting

measuring systems, the lack of linearization in the

sensor’s output signal means that the measured

value will need subsequent correction to make it at all

usable. AHLBORN now offers customers a revolutionary

new feature - also available with hand-held devices. An

option is now available allowing the user to perform

linearization and multi-point correction on ALMEMO

measuring instruments. Not only all the relevant sensor

characteristics but also the linearization or multi-point correction

data are saved in the patented ALMEMO

connector. The measuring

instrument automatically recognizes each sensor that is connected to it and

shows the appropriate measured values precisely in its display.

Thanks to further development of the flexible and intelligent ALMEMO

connector it is now possible to save

complex tables for linearization or multi-point correction - all in the connector itself. For the user this means that it

is now also possible to connect sensors with a non-linear output. The device displays measured values already in

linearized form; this ensures that the whole process can be monitored right from the outset. A further advantage

is the enormous saving in time when evaluating special measuring operations of this nature. For each sensor the

linearization data is saved in the connector; then as soon as the sensor is plugged into the measuring instrument this data is

loaded automatically. The linearization table is buffered in the main working memory on the device for the period of the

measuring operation in question or for as long as the sensor remains connected. With effect from the ALMEMO

2690-8 the

user can use this “KL” option to program linearization processes of this nature quickly and easily. Individual linearization

processes can be applied in the voltage, current, resistance, or frequency ranges. On request - or for other devices - readily

pre-programmed connectors can be obtained from the factory. Various already implemented special-purpose linearizations

are also available.

A sensor’s output signal can also be corrected at various specific points. Inexpensive standard sensors made by third-party

manufacturers can be calibrated. Deviations are then saved in the sensor connector as fine corrections. This can be

performed either by users themselves or on request in advance at the factory - for example for temperature calibrations. It is

now possible to save not only previous characteristics but also over 30 correction points - all in the connector itself.

In the AMR-CONTROL software package the

measuring protocol for a multi-point correction or a

linearization table can be transferred to a table of

reference points. O

ver 30 such reference points are

possible. During a measuring operation the

measured values between these are interpolated on

a linear basis. The AMR-CONTROL software is

included with all our instruments free-of-charge.
