The model 9180 supports force, pressure and torque sensors operating on the strain gauge principle, as well as the connection of position and angle sensors in potentiometric or DC/DC configuration. It also allows the measurement of process signals ± 1 V/ 5 V/ 10 V or 0 ...1 mA, 0(4) ... 20 mA. The present measured value is indicated on the 14-mm-high LED main display, while a second display located directly below provides a reading of the peak value.
Due to the high accuracy of < 0.1 %, the display is particularly suitable for highly accurate measurements. Optionally, it is possible to monitor up to 4 setpoints and deliver the results via relay or transistor outputs. The display can therefore also be used for grouping as well as open and closed-loop control. On activation of an external HOLD signal, the present measured value is frozen on the display. The TARE function is useful for balancing out previous loads, for example. The optional serial interface can be used to transfer measured values and perform device settings. Powerful PC software for this is available on request.

Description

State-of-the-art microprocessor technology has allowed the realization of numerous practical, special functions. Our devices provide operator guidance as a standard feature. Self-explanatory abbreviations greatly facilitate this process so that even inexperienced users are soon able to dispense with the operating manual. First, the type of input signal and type of sensor are specified. Options available are strain gauge units, potentiometers, process signals 0 ...1 mA, 4 ... 20 mA and ± 1 V, ± 10 V, as well as the connection of DC/DC sensors. After that, the calibration process is selected. Here, users can choose between teach-in and calibration in accordance with sensor protocols. The decimal point can be moved as required. The sensor excitation stated in the technical specifications are set automatically on selection of the sensor type, except in the case of process signals. A choice of three excitation is available for process signals. Complete electrical isolation of the measurement channel prevents measurement values from being falsified by ground loops.
