The measuring amplifier GSV-13i is suitable for installation in sensors with strain gages, for example in force sensors, torque sensors, load cells.
The measuring amplifier is characterized by very small dimensions of only 18 mm diameter and 4 mm thickness. The fixing can be done with the help of 2 fixing straps and M2 screws.
The measuring amplifier GSV-13i has an automatic zero adjustment via control line "Tare" and an automatic scaling function "Scale". To set the characteristic, "Tare" is triggered in the unloaded state. In the loaded condition with 100% load, the gain is adjusted via the control line "Scale".
These functions allow zero calibration, calibration and adjustment to be performed in one set-up on the finished product. In contrast to the predecessor model GSV-13L, no strain gauge resistors have to be exchanged for zero point and gain adjustment.
The measured values at the analog output are updated with a frequency of 1kHz.
To trigger the functions "Tare" and "Scale", the corresponding inputs "Ta" and "Sc" are connected to the operating voltage (14V ... 28V) for a period of 3s. The functions are executed on the falling edge. The "automotive" version GSV-13i 05-2.5 / 1000/2 works safely from a supply voltage of 9V to 28V.
The functions "Tare" and "Scale" can be deactivated independently of each other, so that e.g. only the "Tare" function can be executed or that both functions are activated or deactivated. To trigger the scale function, a sensor output of at least 0.05 mV/V must be achieved.
The variants with voltage output 0 ... 10V, zero adjustment to 5V and 4 ... 20mA, voltage output 0 ... 5V, zero adjustment to 2.5V and zero adjustment to 12mA, are order options. Other variants, e.g. with zero adjustment to 4mA or zero adjustment to 0.5V we are happy to deliver as customized version. Other data frequencies from 10Hz to 25kHz can be realized on request.
