Model 3683C: Ultra High Temperature Triaxial Accelerometer

 

   



 

Dytran Instruments, Inc. (www.dytran.com), a leading designer and manufacturer of piezoelectric and MEMS sensors for extreme environments, has introduced model 3683C, a charge mode, triaxial, case isolated accelerometer that operates at up to +1000°F (+538°C), and can survive temperature excursions up to +1,100°F (+593°C).
 
Model 3683C is ideal for vibration monitoring of components in ultra-high temperature environments. Typical uses include the following: gas turbine testing, power plant commissioning, exhaust manifold testing, turbocharger testing, and brake rotor testing.
 
Characterized by its small size and weighing only 65 grams, the product does not mass load test structures and can be used in situations where vertical space is limited. It features a unique ground isolated triaxial design that eliminates the need for using three separate single-axis accelerometers typically mounted on a bulky triaxial mounting block.
 
This model features hermetically sealed housing and our patented Silver Window™ technology for reliable operation at extremely high temperatures. 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 integrity of the hermetic seal. This innovative feature assures continued high temperature operation with minimal loss of piezoelectric crystal insulation resistance due to oxygen deprivation.
 
Available with a sensitivity of 1 - 2 pC/g, model 3683C features a center thru-hole design for 360°cable orientation. It can be easily installed using a 10-32 mounting screw and has two lock-wire holes for securing the sensor to the structure. Dytran offers straight-line or 90° 10-32 hardline cables to mate with three top connectors as well as charge amplifiers that support your application configurations.
