Dytran Instruments, Inc. (www.dytran.com) a leading manufacturer of piezoelectric and DC MEMS sensors has introduced model 3262C, a high-temperature differential output accelerometer that operates up to +1200°F (+649°C), and can survive temperature excursions up to 1,400°F (760°C).
Each aspect of this model is designed for high performance and extended durability in the harshest high-temperature environments. The case isolation, cooling channel, hermetically-sealed super alloy Inconel™ 600 housing and patented Silver Window™ technology make model 3262C ideal for permanent vibration monitoring of gas turbine engines, space applications, nuclear applications, gas and steam turbine power plants.
Dytran’s patented Silver Window™ technology is a key feature of model 3262C. The "Silver Window" on top of the accelerometer housing allows diffused oxygen molecules to pass through at high temperatures, replenishing oxygen to the piezoelectric crystals while maintaining the hermetic seal integrity. This innovative feature assures continued high-temperature operation with minimal loss of piezoelectric crystal insulation resistance due to oxygen deprivation.
The unique crystal design topology allows Model 3262C to exist in rapidly changing thermal environments by exhibiting a high resistance to thermal shocks. The internal components of Model 3262C are made from high-temperature alloys that are “tuned” to a perfect match of thermal coefficients of expansion to stabilize temperature response characteristics. The sensing element is electrically isolated from the external case to avoid signal ground loop interference.
Basic sensitivity is 5 pC/g, the frequency response is +/-10% to 5 kHz. Model 3262C has an industry standard 1.188 bolt circle (ARINC) mounting base made for securing the sensor to the structure with 8-32 thd. mounting screws, and features an integral hardline cable designed to survive the harshest environments.
