4.5Hz Vertical Geophone Horizontal Seismic Sensors
seismic sensors play a crucial role in detecting and monitoring seismic activity, providing important information for disaster management and mitigation, as well as for scientific research and exploration.
Geophones are commonly used in seismology, oil and gas exploration, and civil engineering to detect and measure seismic waves. They are typically deployed in arrays to provide information about the location, depth, and magnitude of seismic events.
The sensitivity of a geophone is typically expressed in terms of its "gain," which is the ratio of the output signal to the input acceleration. The natural frequency of a geophone, which is the frequency at which it resonates, is also an important parameter that determines its performance.

Main Features:
High sensitivity:
The 4.5Hz seismic vertical geophone has a high sensitivity and can capture weak seismic signals. This high sensitivity enables more accurate identification of underground structures and anomalies in geological exploration.
Low natural frequency:
The natural frequency of 4.5Hz makes it suitable for the detection of low-frequency seismic signals, which is particularly important for the detection of deep geological structures. Low-frequency signals can penetrate deeper strata and provide more comprehensive underground information.
Wide range of applications:
The 4.5Hz seismic vertical geophone is not only suitable for geophysical exploration and engineering vibration measurement, but also can be used in various vibration measurement fields such as handheld meters. Its diverse application scenarios make it an important tool in geological exploration and engineering monitoring.
Good consistency:
Each geophone is strictly tested before leaving the factory to ensure that its parameters have good consistency. This helps to obtain accurate and consistent data in different explorations and tests, and improves the reliability of measurement results.
Durability and reliability: These geophones are designed for long-term applications and can operate stably under various working conditions. Its wide operating and storage temperature range (-40 to 80°C) adapts to different environmental conditions and has high durability.
Multiple specifications available:
There are multiple specifications of 4.5Hz seismic vertical geophones available on the market, such as normal sensitivity series, high sensitivity series and high aliasing series. Geophones of different specifications can meet different application requirements and provide greater flexibility.
Lightweight design:
Some 4.5Hz seismic vertical geophones adopt lightweight design, with a moving weight of only a few grams, which is easy to carry and install. This design is particularly suitable for field exploration and application scenarios that require frequent movement.
