Control Accelerometers

Cost-Effective Control Grade Sensors

 

Honeywell’s QA1400 & QA1500 Q-Flex Accelerometers offer cost-effective control grade sensors for a variety of industrial, laboratory and High-G applications.

QA1400 Q-Flex Accelerometer

For a variety of industrial and laboratory applications, Honeywell offers the QA1400 accelerometer. As with the entire Q-Flex family of accelerometers, the QA1400 features a patented Q-Flex etched-quartz-flexure seismic system. The use of an amorphous quartz proof-mass structure provides excellent bias, scale factor and axis alignment stability.

Features

• Analog output
• Environmentally rugged
• Three fastener precision mounting flange
• Field-adjustable range
• Dual built-in test
• Internal temperature sensor for thermal compensation
• Selectable bias temperature sensitivity

QA1500 Q-Flex Accelerometer
Honeywell produces the Q-Flex QA1500 for High-G navigation applications. The QA1500 also features a patented Q-Flex etched-quartz-flexure seismic system. An amorphous quartz proof-mass structure provides excellent bias, scale factor and axis alignment stability.

The QA1500 also includes a current-output, internal temperature sensor. By applying temperature-compensating algorithms, bias, scale factor and axis misalignment performance are dramatically improved.

Features

• High-g acceleration measurement
• Robust stock and vibration capability
• Analog output
• Field-adjustable range
• Four fastener mounting flange
• Built in self-test

Below is a summary of the characteristics of the QA1500 and QA1400 Accelerometers.
