LEMI-152
Product type:
Super broad band induction coil magnetometer
Product description:
• Extremely low noise and wide frequency range LEMI-152 is the perfect choice for an assortment of geophysical applications (MT, CSEM, etc).
• The broadband design allows you to record the high and low-frequency band saving setup time and equipment cost.
• A state-of-the-art preamplifier with low power consumption, and differential output ensures that the sensor can be used with any acquisition station provided that the distance is less than 30 meters.
• Waterproof and rugged, the LEMI-152 is ready for use right after switching on.
• Coil sequencing is handled by the acquisition system.
• Calibration windings for auto-calibration is provided.
Application description:
LEMI-152 induction coil magnetometers are used for measurements of magnetic field variations in the frequency range from 0.001 Hz to 10 000 Hz. Their super-wide bandwidth and low noise make them the ideal sensor for magnetotelluric measurements.
Highlights:
• Lowest noise in class
• Wide range of power supply voltage +/-6 V to +/-15 V
• Low power consumption. More than twice the battery life of other commercial coils. For KMS/LEMI instruments power is supplied from acquisition unit.
• Super-wide bandwidth 0.00025 to 10 000 Hz
• Lightweight < 4 kg
