MAWS HydroMet™ Systems for Meteorological and Hydrological ...

Technical Description ________________________________________________________________
ESD/EMI
The ESD/EMI (Electrostatic Discharge/Electromagnetic Impulse)
design of the MAWS system is based on Vaisala's over 25 years
experience of delivering highly reliable data collection systems for the
most demanding environments and industrial conditions, to over 70
countries around the world.
The high reliability is achieved with professional electronic design,
protecting the I/O lines and proper grounding of the equipment. All
the I/O lines are protected against lightning induced overvoltage
surges. When sensors are installed using short, shielded cables, the
proper protection is achieved using VDR circuits at inputs. Whenever
longer cables are required, additional protective devices - surge
arrestors - are installed on those lines.
