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.
