The in-line amplifier module itself is operated at voltages between 15 V and 30 V, from which it generates a stable excitation voltage to supply the sensor with power. The measurement signals of the sensor, normally ranging between 0 ... 5 mV and 0 ... 10 mV for bridge-connected strain gauges, are amplified to analog 0 ... 10 V.
The sensor characteristics are first roughly preset by means of DIP switches, through an opening in the housing. The fine-tuning of the instrument zero and amplification settings is performed by means of a multiple trimmer, accessible by
screwdriver through holes drilled in the side of the housing. The amplifier connections are realized with sub-D plug and socket; short circuit-proof sensor power excitation and polarity reversal protection for the amplifier power excitation
afford additional safety for installation. If the amplifier has to be mounted to its environment, this is done by clamping the housing or affixing it with an adhesive. The amplifier’s cut-off frequency is > 1 kHz, its weight is < 65 g.
