OTTAWA, Ontario Instantel recently commissioned a state-of-the-art calibration station that directly measures the amplitude response of vibration and overpressure sensors. Response graphs will now be provided with new monitors and factory calibrations for documented proof of compliance with regulatory and industry standards, including the International Society of Explosives Engineers (ISEE) "Performance Specifications for Blasting Seismographs". The new ISEE standard is a step towards improving the reliability of vibration and overpressure measurements.

Conventional calibration procedures test the sensors at only a few select frequencies, and adjustments are made to the response on the basis of these limited data. The new Instantel system allows sensors to be tested and calibrated across a continuous frequency band from 0.5 Hz to 500 Hz, which ensures that the sensors are in compliance across the frequency band. The response curves also define the roll-off characteristics at the frequency limits, so users can better understand the operational frequency band of the sensor.
