Accelerometer resists interference
The Endevco Model 7293A Microtron accelerometer family uses unique variable capacitance microsensors and incorporates special filtering and shielding for EMI and RFI exposure.
New range of industrial accelerometers
This range of industrial Isotron accelerometer types use an Endevco high performance shear design piezoelectric sensor, with integral low-noise hybrid electronics
Additional features include shielding, ground isolation, and sealing against environmental contamination.
The piezoPAK accelerometers measure only 15.2 x 20.3 x 5.3 mm and weigh less than 5 grams.
Five solder pads are provided for power and signal connection.
Endevco can also package the PiezoPAK series into customized housings, allowing for cable/connector options.
The Piezopak accelerometers offer 15 mV/g or 100 mV/g sensitivity with X, Y or Z axis orientation.
Signal ground is connected to the cover and an internal shield.
The standard power configurations include +3 to +16 VDC for the Model 55; +2.7 to +5.5 VDC for the Model 55L; and +10 to +24 VDC with a 2-20mA constant current source for the Model 56.
The output bias is 50% of the supply voltage for the Models 55 and 55L, and 6.6-7 VDC for the Model 56.
Peak linear range is 42% of the supply voltage for Models 55 and 55L, and 2 VDC for Model 56.
An optional temperature sensor with a linear output of 10 mV/*C is also available and is specified by the "T" option in the model number designation.
The temperature sensor has a separate power input and requires a voltage of 4.5 to 10 VDC.
At 0*C, the unit has a 500 mV bias.
