System description

The digital passameter 3903 has a lightweight measuring body with a novel inductive measuring system with 4 mm completely fine measuring range. The gauging force of the measuring system can be selected from approx. 0.7 to approx. 2.0 N as a factory setting. Temperature fluctuations on the measuring body are recorded by an integrated sensor and signalled when a limit value is exceeded. Measuring body and display unit can be operated separately thanks to the modular structure. This simplifies series measuring at the workstation and does not add any disruptive moments into the measurement. Measuring sensor and display are then connected with an optional cable and can be positioned freely. In addition to digital numbers in the display module, there are also precision indicator bars and colour LEDs available for “good” - “bad” selection.

The configuration is done with device keys or additional software. Thus, it is also possible to activate and set functions such as preset value, bar areas, LED colours, measuring modes or password.
