Lightning Warning & Detection
Lightning is one of the most underrated severe weather hazards, yet ranks as one of the top weather killers in the United States. Lightning strikes in America kill about 58 people and injure hundreds of others each year. Unlike other weather hazards that often involve National Weather Service, lightning can occur anywhere there is a thunderstorm. That’s why the National Weather Service conducts an on-going campaign to educate people about lightning risks.

Campbell Scientific has developed The CS110 Electric Field Meter to provide warnings of potential lightning strikes, allowing precautions to be taken that can save lives. The CS110 measures the electric field induced at the ground by clouds located within a 5- to 7-mile radius of the sensor, from which the potential for lightning can be forecast.
In contrast to traditional rotating-vane electric field meters, the CS110 incorporates a reciprocating shutter to intermittently expose a sensing electrode to external electric fields. The reciprocating approach allows for a direct electrical connection to the shutter instead of a problematic rotating contact. The fully closed shutter position on the CS110 also provides a zero-field reference for each measurement cycle, providing for DC error correction.
Campbell Scientific and Wxline have teamed up to combine the CS110 Electric Field Meter and the Strike Guard® lightning detection system to satisfy the most demanding lightning hazard warning applications. The CS110/Strike Guard system provides the user with both continuous electric field measurements and comprehensive lightning detection information. Results are displayed using our RTMC software at local and remote locations.

The CS110 is used for lightning warning applications and in research applications for measuring the local electric field. It measures the vertical component of the atmospheric electric field at the earth's surface. The CS110 sensor is typically part of a larger electric-field system. It includes an integrated CR1000 datalogger, and so can be expanded with the addition of other sensors and peripherals.
Watch how the CS110 is helping keep athletic events at Utah schools safe from lightning danger (after the 15 sec TV station commercial).

CS110 Benefits
- Low power consumption
- Senses potential for lightning, providing warning before lightning strikes
- Easy maintenance—stator easily removed for cleaning
- Extensive diagnostic self-checking for each measurement reduces or eliminates scheduled maintenance
- Rugged construction
- SG000 Strike Guard can be used in conjunction with our CS110 to create a complete lightning-threat measurement and analysis system
The SG000 is an optical-coincidence lightning sensor that detects actual lightning strikes for up to 20 miles away. Available as an option for our CS110 Electric Field Meter, the SG000 Strike Guard is used in conjunction with the CS110 to create a complete lightning-threat measurement and analysis system. Data from the two sensors can be used to control warning systems and to help personnel make evacuation and shutdown decisions. We highly recommend buying this system with the CS110.
SG000 Benefits
- Fully integrates into CS110 system
- 20-mile detection radius
- Avoids false alarms with patented technology
