(NewTek: Pennsauken, NJ) -- Seismic surveys are a noninvasive method used by exploration companies to search for oil and gas below the Earth’s surface. The testing is conducted with vibroseis trucks that deliver a low-frequency vibration from a seismic vibrator using a base plate that strikes the ground. With every sweep, outgoing vibration signals from the trucks strike the ground at varying speed and frequency. Returning signals help identify ground characteristics to create a profile that identifies areas of oil and gas deposits.

NewTek LVDT displacement sensors are deployed on the seismic vibrator trucks to provide feedback on the position of the base plate that strikes the ground to emit vibrations necessary to conduct seismic surveys. Knowing the position of the base plate is important to controlling the vibrations being sent into the earth and that can vary in frequency to detect various ground characteristics. Position feedback also verifies whether the base plate is in a deployed or storage position.
