Miniature Accelerometer operates in temperatures to +900°F.

Press Release Summary:

Miniature Accelerometer operates in temperatures to +900°F.

May 23, 2012 - At 5 g and 0.39 in. high, model 3316M1 utilizes planar shear technology and features charge mode element mounted in hermetically sealed, miniature Inconel® housing. Silver window on top cover of housing provides oxygen access to crystal at high temperatures while maintaining hermetic seal. Along with sensitivity from 1-2 pC/g, unit offers 10,000 Hz upper frequency response and has 10-32 tapped hole and 10-32 radial connector. Model 3316C, similar to 3316M1, comes with 5-40 tapped hole.

Dytran Instruments Introduces Miniature High Temperature Accelerometers

Press release date: May 21, 2012

Chatsworth, California, USA - Dytran Instruments, Inc. (www.dytran.com) a leading manufacturer of piezoelectric and DC MEMS accelerometers, force and pressure transducers and associated electronics, has introduced the model 3316M1, a high temperature accelerometer featuring a charge mode element mounted in a hermetically sealed, miniature Inconel® housing.

Capable of operating at temperatures up to +900°F (+482°C), the Dytran model 3316M1 utilizes the latest in planar shear technology. In order to operate at such high temperatures, the model 3316M1 was designed with a unique, Dytran patented technology. Units employ a "silver window" on the top cover of the accelerometer housing, which provides oxygen access to the crystal at high temperatures while maintaining the unit's hermetic sealing.

The Dytran model 3316M1 weighs just 5 grams and has a height of just 0.39 inches (9.8 millimeters), making it ideal for use in even the smallest of locations. Offered with a sensitivity between 1 and 2 pC/g and with 10,000 Hz upper frequency response, the model 3316M1 has a 10-32 tapped hole and 10-32 radial connector (exact sensitivity is provided on the calibration certificate supplied with each sensor).

Similar to the model 3316M1 is the model 3316C, which features the same basic characteristics. Model 3316M1 is offered with a 10-32 tapped hole and model 3316C is offered with a 5-40 tapped hole.

With its durability, broad operating temperature range and miniature, lightweight design, the Dytran 3316C series is ideal for high temperature environments where mass loading is a concern including automotive vibration studies, exhaust system analysis, engine vibration analysis, and Environmental Stress Screening (ESS).

At elevated temperatures there is a chance for EMI/ground loop interference, and due to its miniature size, the Dytran 3316C series has ground connection to the housing. It is therefore recommended to use model 6998 or 6989 (single and triaxial, respectively) isolated mounting blocks in order to isolate the sensor from the mounting surface. Additional recommended accessories for the 3316C series include the model 6946A and 6979A hardline cable assemblies and model 4752B in-line charge amplifier.
