Overview

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.

Technical Description

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.

CS110 Cleaning and Calibration with Documentation
The 31479 requires an RMA (Return Material Authorization) from Campbell Scientific. The CR1000 within the CS110 is calibrated to meet the factory specifications and is tested over the standard temperature range (-25° to +50°C). This service also includes replacing the stator gasket, cover gasket, and desiccant. The stator is then cleaned and the CS110 is calibrated. A calibration report is provided for the CS110.

Compatibility

IMPORTANT!
An embedded CR1000M datalogger module (ordered as p/n 18292) is required for every CS110 purchased; see Common Accessories in ordering information.

Generally, the CS110 should be run with the latest released CR1000 operating system (OS) available via "Support" on this website. However, CR1000 OS version 27.05 should NOT be downloaded to standard CS110s. OS version 27.05 was built to accommodate the ~40,000 v/m efields measured on ocean buoys. The special OS also requires a capacitor change on the CS110 panel board.

The CS110 should not be run with OS 28 (CR1000.Std.28.obj). A bug in OS 28 prevents changing the setup "Constants" via the keyboard or the terminal emulator.

Data Logger Considerations

The internal CR1000M (required) can be interfaced to another data logger via the Power/SDM cable if the application requires an additional data logger.

Programming

The CR1000’s on-board programming language, CRBasic, provides data processing and analysis routines that support user control over sample (measurement) rates and setting of alarm conditions. LoggerNet Datalogger Support Software facilitates programming, communications, and data retrieval between the CS110 and a PC.

Using the CS110 as a Weather Station

The CS110 has sealed connectors for attaching meteorological sensors and three digital control ports for controlling external devices and/or triggering alarms. The embedded CR1000 datalogger measures the sensors, processes the measurements, stores the data in tables, and can initiate communications.

Compatible Communication Devices

Communication options compatible with the embedded CR1000 include direct connect, Ethernet, phone modems (land-line and cellular), radios, short haul modems, GOES satellite transmitters, and multidrop modems.

Zero Electric Field Cover

The 17642 Zero Electric Field Cover (ordered separately) is used to check the electric field offset voltage of the CS110. If the measured electric field is ≥|60 V/m| with the Zero Electric Field Cover on, then inspection and cleaning of the electrode surfaces is recommended.

SG000 Strike Guard Lightning Sensor

The SG000 (ordered separately) can be used in conjunction with our CS110 to create a complete lightning-threat measurement and analysis system. This system combines the advantages of two complementary lightning-warning technologies. The SG000 reports actual lightning strikes occurring at distances up to 20 miles—providing a comfortable warning time for incoming storms. The CS110 reports electric fields associated with local thunderstorm development—providing a warning prior to lightning strikes.
