Charge converters and charge amplifiers transform charge output signals with high-impedance to low-impedance voltage or current. Transducers connect piezoelectric, capacitive, or other charge-producing sensors to an amplifier that conditions the signal and outputs the voltage or current to a display such as a front panel, touch screen, or computer monitor. Charge converters and charge amplifiers are low-cost devices that are used in the measurement of variables such as acceleration, force, temperature, and dynamic pressure. Some charge converters and charge amplifiers include a voltage excitation supply or a current excitation supply that powers the sensor. Others include integral or pre-packaged sensors. |
Products & Services Related to Charge Amplifiers and Charge Converters
Current Loop Converters
Current loop converters convert an analog or digital signal to a current loop output such as 4-20 mA or 0-20 mA.
Data Acquisition Input Modules
Data acquisition input modules accept sensor and other signal output for data acquisition systems. They may include signal conditioning prior to the analog-to-digital conversion stage.
LVDT and RVDT Signal Conditioners
Linear variable differential transformer (LVDT) and rotary variable differential transformer (RVDT) signal conditioners are devices that translate the linear or rotary movement of a ferromagnetic armature into an AC voltage that is proportional to the armature position.
Signal Converters
Signal converters contain inputs for one type of signal and outputs of another. Features can also include filtering and amplification or attenuation.
Voltage Converters and Voltage Inverters
Voltage converters and voltage inverters accept voltage input and provide a scaled voltage output. Conversion types include scaling up a low-level signal, voltage doubling, and inversion (converting a positive voltage to negative and vice versa).
