INFRASOUND SENSOR – HERMES
Hermes is a premium-quality INFRASOUND SENSOR to detect low-frequency (not audible) sound waves produced by natural phenomena such as volcanic eruptions, adverse weather conditions,lightning, asteroids, wave motion, outgassing and minor volcanic explosions,debris-flow, rapid mass flows such as snow avalanches and landslides, earthquakes and related ground shaking, sea storms, mountain waves.
Description
HIGH PRECISION MEASUREMENTS
HERMES is a differential infrasonic sensor based on differential pressure measurement and the use of an acoustic filter to eliminate the stationary component of atmospheric pressure. Hermes performs high precision / high reliability measurements over a wide frequency bandwidth and it’s capable to detect low-frequency (not audible) sound waves.
INFRASONIC WAVES SOURCES
In addition to strong volcanic eruptions, there are many sources of infrasonic waves, most of which are produced by natural phenomena such as adverse weather conditions, lightning, asteroids, wave motion, outgassing and minor volcanic explosions, debris-flow, rapid mass flows such as snow avalanches and landslides, earthquakes and related ground shaking, sea storms, mountain waves. Artificial sources of infrasonic waves that can be measured are quarry blasting, TNT/Gas blasting during avalanche control, nuclear explosions and shock waves.
FEATURES
- BROADBAND (0.033* HZ TO 200 HZ)*LOWER FREQUENCIES ON REQUEST
- HIGH DYNAMIC RANGE (110 DB) LOW NOISE (-62DB PA² /HZ, REL TO 1 PA AT 1 HZ)
- LOW POWER
- LOW COST
- ROBUST PHYSICAL BUILD QUALITY AND SEALED ELECTRONICS
VARIOUS SENSOR TYPES
A range of sensors with different sensitivity and dynamics as well as frequency ranges are able to cover the amplitude and frequency ranges of most of these infrasound sources, allowing effective monitoring.
ROBUST AND LOW POWER CONSUMPTION
The rugged casing together with the low power consumption guarantee the employment of HERMES sensors also in hostile environment.
