High Temperature IEPE Accelerometer

Dytran 3525A3 – High Temperature IEPE Accelerometer !

Dytran Instruments, Inc. has recently introduced model 3525A3, a single-axis, high temperature IEPE Accelerometer .  Model 3525A3 is hermetically sealed, quartz accelerometer with a built-in impedance converting amplifier, capable of operating continuously at up to 200ºC.

Uniquely designed internal electronics allow the measuring of shock and vibration in high-temperature applications without the need for external charge amplifiers.  Thus, reducing the cost and complexity of high-temp testing.

Dytran have tested 3525A3 sensor lots at 200°C   for 1500+ continuous hours in a thermal HALT/HASS chamber as part of the successful qualification.

The 3525A3 utilises an inverted quartz sensing element to minimise the unwanted effects of base strain on the accelerometer signal. In addition, the use of quartz provides long term thermal stability and a low thermal coefficient of sensitivity.  Therefore, there is very little change in sensitivity when the sensor goes from room temperature to 200°C.

The small stainless steel housing of the 3525A3 makes it ideal for use in locations inaccessible to larger  accelerometers.

Typical uses for model 3525A3 include applications such as, down-hole oil industry, environmental test chambers, HALT/HASS chambers for control, automotive applications including engine and exhaust hot zones, as well as for any general purpose high temperature IEPE applications.

Finally, it has a sensitivity of 10 mV/g and a 5 to 10,000 Hz frequency range (±5%). Model 3525A3 features a top mounted 10-32 micro coaxial connector and is installed using an integral 10-32 mounting stud.
