Seismic sensor A/1600

• Supply Voltage - 15/35V • Supply current - 2 - 20mA • Bias voltage (20°C) - 11/14V • Mounting - base tapped 10/32UNF x 4mm deep • Microdot connector, 10/32 UNF thread (T) • TNC connector (TC) • Welded Construction Applications Industrial Structural Testing Seismic Vibration Measurement The A/1600 range of accelerometers are ultra high output, multiple shear plate voltage accelerometers. The use of shear plate construction provides near total isolation from mechanical inputs other than acceleration, thus safe guarding measurement integrity in applications where vibration is accompanied by high dynamic strain levels. Generalising, these conditions are prevalent where modal frequencies are low, and are thus associated with vibration surveys of large structures. Ideal for use in civil/heavy engineering or Seismic applications the A/1600 provide high output along with low frequency measurement capability with high measurement integrity. As with all IEPE accelerometers the A/1600 requires a constant current supply in the range of 2 to 20mA, this can be provided by the associated measurement front end (if available) or by the range of voltage source modules in the DJB Instruments range of instrumentation. For applications requiring high temperature usage as well as high outputs, a Charge Output version of this accelerometer is available (A/600). Calibration All DJB Accelerometers are calibrated on site prior to despatch, and are accompanied by a calibration chart with temperature and frequency responses listed.
