Innovative Ultra High Temp. Accelerometer +1200°F

Featured Product from Dytran Instruments, Inc.

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.

A unique feature of this accelerometer is Dytran’s patented Silver Window™ technology which allows the sensor to withstand temperature excursions hundreds of degrees higher than specified.  A "silver window" on the top cover of the accelerometer housing 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 minimal loss of insulation resistance due to oxygen deprivation.

Every aspect of this model is designed to provide high performance and long durability in the harshest high temperature environments.  The 3335C's main applications are: testing gas and steam turbines for power generation in aircraft; 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.
