The mains-operated, microprocessor controlled single-channel charge amplifier Type 5011 converts the electrical charge produced by piezoelectric sensors into a proportional voltage signal.

 Features

• Large measuring range

• Wide frequency range

• Automatic zero correction

• Adjustable low-pass filter and time constant

• Various options and versions provide optimum adaptation to
  the measuring problem

Description

The main features of the instrument are its continuous measuring range adjustment range from ±10 ... ±999 000 pC and convenient adjustment of the parameters with a two-line LC display. The values entered are retained in the event of an interruption in the power supply.
A built-in IEEE-488 parallel interface or a serial RS-232C interface is available as an option. This enables all set values to be entered or queried. Transmission of data measured is not possible.
The version ...Y50 additionally has a drift compensation and is used in engine measuring technology with uncooled sensors.

Application

This amplifier serves mainly to measure me cha nical quantities, e.g. pressure, force or acceleration.The instrument dimensions are DIN standard ized and it can be supplied in a desktop or rack mount case.

The principle measurement without calculation:

• Set sensor sensitivity

• Select display scale

• Sensor sensitivity and scale are displayed

• Set the signal output of the data acquisition unit (recorder,oscilloscope...), for example to 1 V/unit (1 V/cm)

• The display appears directly in mechanical units according to the display scale selected
