A charge-type piezoelectric accelerometer is robust and designed specifically for high-temperature vibration measurement. The unique design of Dytran’s charge sensors delivers a high dynamic range, long-term stability and ruggedness.
Unlike IEPE sensors, they lack internal electronics, outputting a high-impedance charge signal that requires an external charge amplifier to convert signals into usable voltage.
Key features and benefits
Charge accelerometers are specialised sensors that generate an electrical charge proportional to the vibration or shock they experience. They do not contain microelectronics, which defines their unique capabilities and operational requirements.
High-Temp Operation
Charge accelerometers have a lack of internal electronics, they can operate in extreme heat where standard sensors would fail.
Wide Dynamic Range
They offer an excellent performance across a broad range of frequencies and acceleration levels.
Measurement Flexibility
Charge systems allow you to adjust gain, filtering and time constant at the external amplifier, giving you more control.
Radiation Toleranace
Since they have no internal semiconductors, they are well-suited for use in nuclear and high-radiation environments.
