The model 9180 supports force, compression or torque sensors based on strain gauges as well as the connection of displacement or angle sensors in potentiometric or DC/DC versions. Furthermore, process signals ± 1 V/ 5 V/ 10 V or 0 ...1 mA, 0(4) ... 20 mA can be measured. The active measured value can be read on the 14 mm high LED main display and the peak value can be read on a second display directly below the main display.
Thanks to the low error of measurement of 0.1 %, the indicator fulfils higher accuracy requirements in particular. As an option, it is possible to monitor up to 4 limit values and supply the result to the controller via relays or transistor outputs. This means that the process value indicator can be used for classification, but also for control and regulation tasks. When an external HOLD signal is activated, the measured value is recorded in the display. The TARE function is useful, for example, for taring off preloads. Measured values can be transmitted and device settings made via the optional serial interface. Powerful PC software is available on request.
Many practical special functions have been realised using the latest microprocessor technology. The menu-guided setting of the devices is obligatory. It is kept so simple with self-explanatory abbreviations that even the inexperienced user will soon be able to manage without an operating manual. Firstly, the model of the input signal or sensor is defined. Selectable are strain gauge or potentiometer or process signal 0 ...1 mA, 4 ... 20 mA or ± 1 V, ± 10 V, as well as DC/DC sensors. The calibration method is then selected. Here the user can choose between teach-in or calibration according to sensor protocol. The decimal point can be placed anywhere. The excitation voltages listed in the technical data are set automatically when the sensor type is selected, except for process signals. For process signals, three excitation voltages can be freely selected. Complete electrical isolation of the measuring channel prevents measured value distortions due to ground loops.

- Min/Max value display
- Powerful software for recording and archiving measurement data
TASK
The requirement is to calibrate equipment in calibration laboratories under precisely defined environmental conditions. These rooms are air conditioned in order to ensure specific environmental conditions. Parameters such as temperature, air pressure and air humidity still need to be constantly monitored and logged, however. This is the job of a PC, which receives the relevant data via an RS232 interface.
SPECIFIC REQUIREMENT
Recording data on the PC from various sensors. Archiving measurement data for post-analysis.
SOLUTION
Digital indicators (model no. 9180) are used to record environmental readings at a total of 12 positions. The digital indicators transfer the recorded data to a converter via the built-in RS485 interface. The converter then converts the data into a form that can be read by the PC via its RS232 port. In the PC, the DigiVision software logs and visualizes this measurement data. DigiVision can process up to eight channels at once. To be able to capture 12 measurement points simultaneously requires the use of the controller communication tool.
This works as follows:
The user creates two device lists, each containing six devices. Then using the free TCP IP controller communication tool, the user creates a special macro. The tool loads the first of the two device lists and starts and stops the measurements. The tool then repeats this process with the second device list. The entire measurement routine can be repeated continuously under timer control.
