Vibro-Meter's CA 202 Piezoelectric Accelerometers are built with external charge amplifiers. They are generally used for applications that involve heavy-duty gas and steam turbines. They are also utilized for applications with an expanded temperature range. These devices showcase working temperature rates that range from -67 to 500°F (-55 to 260°C), and frequency levels that range from 0.5 to 5,000 Hz.
