The model 9243 amplifier module is used wherever measurement signals from strain gauge, potentiometric or DC/DC sensors need to be converted into Standard signals. Simple installation on standard DIN mounting rails makes it possible to place the measuring amplifier directly on site, close to the sensor, without any problems. An IP65 version is available for particularly harsh environments.
The wide power supply range and the choice between AC or DC enable operation on standard control cabinet supplies. A high-precision internal reference voltage source is available for calibration purposes. A calibration shunt can also be connected via two separate terminals. This makes it possible to detune a strain gauge sensor for calibration or just to check the measuring chain.
A high-precision amplifier takes over the amplification of the sensor signal. The required amplification factor is roughly adjusted via DIP switches and finely adjusted using a potentiometer. Current and voltage outputs are available simultaneously. The sensor supply is taken over by the amplifier module so that no additional voltage source is required. It can also be set in the steps 2.5 V, 5 V, 10 V via DIP switches. The maximum supply current of 35 mA allows several strain gauges to be connected in parallel at the same time, e.g. for measured variable addition. Errors of measurement caused by changing cable lengths, but also by temperature fluctuations on the sensor cable, are avoided by sense lines measuring the actual excitation voltage directly on site at the sensor itself (6-wire technology). Fluctuations there are immediately corrected by the electronics. The cut-off frequency of the amplifier is reversible between 10 Hz and 1 kHz. The DIP switches for configuring the device are easily accessible under a flap at the top of the cabinet.
- Optimum adjustment to given conditions
- Variable measurement range of complete system
- Implemented using standard products
TASK
In the custom machinery sector, special annular load cells are sometimes needed that have a large internal diameter in order to accommodate bulky workpieces or tools. Usually the quantities required are too low for it to be economic to produce a short run of custom sensors.
SPECIFIC REQUIREMENT
- Standardized output signals for analysis of sensor results by a measuring instrument
- Technical solution using standard products
- Rigid and compact system
SOLUTION
Three burster 8402 miniature load cells are mounted on a base ring of the required internal diameter, spaced apart by 120°. The sensors are held in their position in the plane by a guide ring, which fits around the sensors with sufficient clearance and is connected to the base ring by locating pins. The force is applied via a third, through-hardened ring, which is connected to the two other rings by locating screws. Conical spring washers are inserted beneath the screw heads to provide a stable initial load throughout the assembly. The burster 9243 instrumentation amplifier can be used to provide excitation for the three sensors and to output a summated value of their measurement signals. The complete assembly therefore looks and behaves like one sensor and can also be calibrated as such. Apart from price, there are further reasons for favouring this solution:
- It takes far less time to manufacture the three rings than to produce a custom sensor.
- Since the sensors are all standard components, there is a guaranteed ready supply of spare parts.
