Signal-amplifier for resistive force and strain sensors – Dynamic applications Models X-201-04 Strain gauge amplifier with 4…20 mA and 0…10 V output, with PLC input for zero reset DIN-rail mounting Aluminium field housing PLC input for cyclical zero point adjustment High measuring speed of up to 5000 Hz Sensitivity from 0,5 mV/V up to 4 mV/V for the connection of strain gauge sensors Featuring both voltage and current output simultaneous The bridge excitation can be selected between 5 V or 10 V Application The X-201 is designed to amplify low-level signals from force and strain-sensors basing on the strain-gauge technique. It is considered for signal conditioning and interfacing to PLC's or any control-unit with analogue inputs. The X-201 has a PLC input for process controlled zero reset. This way of zero nulling is very effective in applications with a cyclical signal, where the force is at a certain moment zero. If the X-201 is nulled in this very moment, all drifts and zero-offset are tared and therefore completely suppressed. This way of nulling can be used in dynamic applications like stamping machines, injection- and die casting machines. The amplifier is available for DIN-rail mounting and in a robust aluminium f

Zero point adjustment with digital input for PLC The X-201 has a PLC input for automatic zero point adjustment (reset). The internal nulling circuit forces the output to zero, as long as a voltage is present at the digital inputs Reset A, Reset B (high-active). If a load is present before nulling, it will be suppressed. By switching the voltage at the Reset input to zero, the X-201 will change to "operate" mode. The output will show the signal relative to its internal zero (relative measurement). The nulling circuit consists of a storage capacitor. This capacitor shows a small drift over time....

Th e bridge excitation can be selected between 5 V or 10 V. As a general rule, low impedance sensors should be driven with 5V whereas high impedance sensors can be operated with 10V. If you're in doubt, select the lower excitation voltage. Signal-amplifier for dynamic applications

Th e onboard low-pass filter is switched on and off by toggling the appropiate DIP-Switch. It is recommended to reduce the bandwith, because this eliminates high frequency noise and gives more stability to the readings. If your application needs more speed, you can switch off the low-pass filter in order to achive a bandwith up to 5'000Hz. Output signal The X-201 offers two calibrated outputs at once, a voltage ouput and a current output. The relation between these two outputs is strictly proportional, in other words, if the voltage output is forced to 100%, the current output will also go to...
