The Dytran model 3335C takes high-temperature vibration testing to a new level. The single axis charge mode accelerometer operates up to +1200°F (+649°C)--a breakthrough product in the sensor field. The model has 1-2 pC/g sensitivity with a 2500 upper-frequency range. The 3335C is case ground isolated and hermetically sealed.

Every aspect of this model is designed to provide high performance and long durability in the harshest high-temperature environments.  Its base isolation, low mass, hermetically-sealed super alloy Inconel™ 600 housing and patented Silver Window™ technology make it ideal for use in high-temperature applications. Units employ a "silver window" on the top cover of the accelerometer housing, which allows a diffused oxygen molecule to pass through at high temperatures, replenishing oxygen to the crystal while maintaining the hermetic seal integrity.  This innovative feature assures continued high-temperature operation with no loss of insulation resistance due to oxygen deprivation.

Typical uses for model 3335C include but are not limited to the following test applications: gas and turbine engine testing, nuclear power plant testing, exhaust and catalytic converter studies, rocket engine testing, automotive engine testing, and any other vibration measurement testing within high-temperature environments.
