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
The new Endevco model 87 delivers the industry's best signal to noise in a compact seismic accelerometer through state of the art integrated electronics.
Plus, at 170g, the device is 70% lighter than traditional IEPE seismic accelerometers.
It is hermetically sealed against environmental contamination, available in 1 or 10V/g sensitivity, and provides near-DC frequency response flat to 0.05Hz.
The model 87 incorporates an ultra-low-noise hybrid circuit operating in a constant current mode.
A simple two-wire system transmits low-impedance voltage output and required power.
Signal ground is electronically isolated from the outer case and the mounting surface to prevent ground loops.
A specially designed cable assembly is available as an optional accessory.
Additional features include full-scale output voltage of 5V, temperature range of -20C to 100C, overload protection to 400g, low impedance output at less than 10ohm, a stainless steel case, and a top-mounted two-pin connector.
Dimensions are 30mm diameter hexagonal configuration, and a 40mm height not including connector, and 56mm height including connector.
"The new model 87 delivers an unprecedented combination of low noise and low weight in an advanced accelerometer for critical seismic measurements", said James Fisher, Endevco Director of Marketing.
"It is another example of Endevo's commitment to setting industry standards for performance and value for our customers".
