CS110

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.

Note: For a complete system that uses the CS110 Electric Field Meter Sensor, refer to the LW110 Lightning Warning System page. 

The CS110 uses a reciprocating shutter instead of the traditional rotating vane field mill. The reciprocating shutter is electrically connected to ground potential by a flexible stainless-steel strap. The strap operates below its fatigue limit, resulting in an ultra-reliable electrical ground connection to the shutter.

The reciprocating approach provides better low-frequency error performance than the traditional rotating vane field mill because it has a convenient zero-field (closed shutter) reference. The zero-field reference allows the CS110 to measure and then correct for electronic offset voltages, contact potentials, and leakage currents of each individual measurement (Patent Pending).

The CS110 also contains circuitry to measure and compensate for insulator leakage currents occurring on the charge amplifier input, eliminating measurement errors caused by fouled insulators. If insulator surfaces become conductive because of surface contamination, a leakage current compensation circuit applies an equal and opposite polarity current to the charge-amplifier input that prevents saturation of the electronics.

Warranty

The CS110 has a one year warranty against defects in materials and workmanship. Campbell Scientific does not warrant that the CS110 will meet customer’s requirements or that its operation will be uninterrupted or error-free.

Atmospheric or local electric field conditions or different site characteristics may cause false information, late data, or otherwise incomplete or inaccurate data. The CS110 only measures conditions that make lightning more likely. Just as with weather forecasts, the CS110 measurements only help assess the probability of lightning. Lightning can occur causing personal injury, even death, or damage to property without any warning from the CS110.

Campbell Scientific is not liable for special, indirect, incidental, or consequential damages from the use, failure, or malfunction of the CS110. A full statement of the CS110’s Warranty is contained in the CS110 Manual.
