Kistler Type 5155A Multi-Channel Amplifier
The purpose of the Kistler Type 5155A Multi-Channel Amplifier with 1, 2 or 4 channels is to convert the charge signal from piezoelectric sensors or the signal from thermocouples into a proportional voltage signal. This amplifier has been developed for industrial applications, in particular for injection molding machines.
The Kistler Type 5155A Multi-Channel Amplifier is provided with one, two or four charge amplifier modules. The two measuring ranges of the charge amplifier inputs can be switched over for each channel individually by remote control. Amplifiers equipped with temperature inputs are provided with 1 charge amplifier and 1 temperature amplifier or 2 charge amplifiers and 2 temperature amplifiers. All charge amplifier modules contain at the input a capacitive negative feedback amplifier in hybrid design with an extremely high insulation resistance.
