| | May 24, 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, is pleased to announce the release of its new brochure titled “Sensors and Systems for Static and Dynamic Acceleration Measurements”.
MEMS DC response sensors are used for a variety of high sensitivity, low frequency vibration measurements of acceleration and deceleration and long duration transient motion events within low-to-medium frequency instrumentation applications, extending down to DC (steady state). These types of sensors are known for their reliable performance over temperature, and their ability to withstand higher levels of shock and vibration inputs, with fast response times and great accuracy over temperature.
Included among the models highlighted in the new brochure is the 7500A series, a family of ultra low noise, single axis, MEMS DC accelerometers. Offered with a choice of eight different models with measurement ranges between 2g and 400g, these high precision variable capacitance (VC) sensors combine an integrated VC chip with high drive, low impedance buffering for low level acceleration measurements. The sensors offer a low-end frequency response down to DC, with an upper frequency range between 400 and 2,500 Hz with differential output. Units are rugged to 5,000g shock and operate from +9 to +32 VDC power. The Dytran 7500A series accelerometers are often specified for tilt measurements, crash test, seismic monitoring, and other low frequency vibration measurements. In addition, Dytran has recently launched a triaxial version, the 7503A series.
Another popular series found within the brochure is the Dytran 7600B series, a family of single axis, high performance VC accelerometers, designed for use as a drop-in replacement for piezoresistive units in new or existing zero-to-medium frequency instrumentation applications. Available in six different models, with ranges from 5g to 200g, the Dytran 7600B series incorporates a MEMS capacitive sensing element and an advanced ASIC to simulate piezoresistive bridge operation, as well as an integrated VC accelerometer chip with high-drive, low impedance buffering. Units respond equally well to both DC and AC acceleration. The Dytran 7600B series accelerometers utilize the same power supply as traditional piezoresistive and strain gage sensors, allowing them to operate as standalone differential output accelerometers or in place of piezoresistive bridge-type accelerometers. These sensors are ideal for crash test, ride quality, flight testing and measurements of longitudinal vehicle acceleration and deceleration.
As a lower cost alternative, Dytran also offers the 7521A series and 7523A series of single axis and triaxial, respectively, DC response accelerometers, also designed for low-level low frequency vibration measurements, with stable operation over a broad temperature range. Units occupy a small footprint and feature a lightweight aluminum housing, with an integral cable and total weight of just 3.7 grams (single axis) and 10 grams (triaxial).
