DC Accelerometers

The family of high-performance single axis variable capacitance (VC) accelerometers available in different models with measurement ranges between 2 and 400 g.  These high-precision accelerometers combine an integrated DC accelerometer chip with high drive, low impedance buffer for low-level acceleration measurements.

Tailored for zero-to-medium frequency applications, the DC ranges features a low end frequency response of 0 Hz, and upper frequency range between 400 and 2,500 Hz.  This DC accelerometer module contains a MEMS capacitive sensing element, a custom integrated circuit amplifier, low-noise electronics and differential output, housed in lightweight titanium. Each units are hermetically sealed for reliable operation in high-humidity and dirty environments.


Miniature / ESS

The miniature family has a wide selection of ultra-miniature teardrop size low-profile type to ring shaped type. They are IEPE type accelerometer with a sensitivity of 10 mV/g, designed to adhesively or screw mount in spaces typically inaccessible to other types of accelerometers.  The smallest sensor weighs just 0.6 grams.

Featuring a quartz shear sensing element in lightweight titanium housing, All units within the series have a sensitivity of 10 mV/g and adhesive mounting capabilities.  They differ only in terms of their type of connector, environmental seal and electrical isolation.


General Purpose

Wide range of model with available sensitivities from 5 mV/g to 1000 mV/g, the general purpose models features ceramic shear sensing element packaged within rugged titanium housing, with a radial connector with option of adhesive or 10-32 stud mounting capabilities.  Optional Transducer Electronic Data Sheet (TEDS; per IEEE 1451.4) capabilities are also available for larger channel count applications.

Units are base isolated to avoid EMI/ground loop interference and incorporate low-noise JFET electronics.  They are also hermetically sealed for reliable performance in high-humidity and dirty environments.


Triaxial

The triaxial accelerometer family are available in various designs from general purpose to ultra-miniature IEPE triaxial accelerometers; One of the smallest and lightest weighs just 0.8 grams, and is designed to mount in spaces inaccessible to other types of accelerometers.

There are choices of 1 to10 mV/g sensitivity, the triaxial design incorporates shear sensing elements with integral electronics, packaged in a robust, lightweight, welded titanium cube, with terminating to a 4-pin connector, adhesive and screw mounting capabilities.  There are ultra-miniature teardrop sensors which are capable of operating at temperatures up to +300°F (+149°C).  


High Temperature
The high temperature accelerometer family is usually of piezoelectric charge mode accelerometer designed to offer reliable performance in temperatures up to +500°F (+260°C). The design features a hermetically sealed, all stainless steel design, with the sensor operating in compression mode.  Total weight is just light and certain units feature a standard 10-32 radial connector with 10-32 tapped mounting hole.

Shock

The shock accelerometer family are highly rugged IEPE accelerometers with a natural frequency of greater than 100 kHz, designed to measure severe shocks and other extreme short duration events.

 High shock measurements are typically characterized as such above the range of 2,500 g’s.  In order to accurately measure shock levels of this magnitude, accelerometers must have a high natural frequency, rugged construction and be fairly compact in size. Available in various models, with full scale ranges between 2,500 and 70,000 g. The shock accelerometer family series features a quartz crystal sensing element, operating in compression mode, housed in stainless steel housing for a total weight of 6 grams.  Units are electrically base isolated and feature a broad frequency response.

 The shock accelerometer family is available in several different mounting configurations to suit individual user requirements: an integral 1/4-28 mounting stud; integral 10-32 mounting stud and metric M6 x 1.0 integral mounting stud.  All other specifications remain the same.


Industrial

The Industrial family series is a high-sensitivity, IEPE accelerometers, certain models featuring a ring typed thru-hole mount and radial 2-pin connector, allowing the sensor to be turned 360° prior to securing for greater ease of installation.

 The series is available in various models and sizes with sensitivities of 100 mV/g to 500 mV/g, a low-end frequency response of 0.5 Hz and excellent low-noise performance characteristics.

 Design of the series incorporates a ceramic shear sensing element, packaged in highly rugged stainless steel housing.

Certain series models are also directly compatible with the Dytran model 6194 Immersion Proof™ sealing boot. When used together, sensors are able to remain fully functional when used in an IP65 environment.  The sensors are also hermetically sealed for reliable operation in high-humidity and dirty environments and case isolated to avoid EMI/ground loop interference.


Airborne

The Airborne family expressly designed for use in Health and Usage Monitoring Systems (HUMS), the various models are an IEPE piezoelectric accelerometer, featuring typically sensitivity of 10mV/g with a frequency response of 1.5 to 5,000 Hz in a highly rugged stainless steel package weighing around 20 grams.

The distinguishing feature of family series is the Dytran developed integral mounting bracket design, facilitating improved sensor performance while eliminating costs associated with separate mounting brackets.  The miniature accelerometer is mounted within the bracket at the point where the cable and bracket are joined.  It also offers reduced mass, as compared to conventional sensors and mounting brackets.  Typical models are hermetically sealed for reliable operation within high-humidity and dirty environments as well as case isolated, to avoid EMI/ground loop interference.


Specialty

The Specialty family make up of specialised design accelerometers for dedicated application. One of them is a triaxial IEPE seat pad accelerometer, designed to be installed between the rider and vehicle seat in transportation-related applications.  The model 5313A utilizes an integral 10-foot cable, terminating to three (3) BNC plugs. Construction of the Dytran model 5313A consists of a thin rubber cushion containing the model 3134M1 accelerometer.  The model 3143M1 is mounted within the rubber housing, or may be used as a stand-alone accelerometer. The model 5313A seat pad accelerometer conforms to ISO 8041, which specifies the performance and tolerance limits for instruments designed to measure vibration values in human vibration response assessments.

Featuring titanium construction, 10 mV/g sensitivity and adhesive mounting, the model 3243A incorporates a 2-meter integral cable with a splash-proof boot at the point of sensor and cable connection. The hermetically sealed cable-to-accelerometer boot seal makes it possible for the sensor to be temporarily submerged during testing. Units are case isolated to avoid EMI/ground loop interference.
