Each of these different gas clouds will produce the same ELDS reading of 1.0 LFL.m, however
only the 1
st
example where the gas cloud is very small actually has a potentially flammable
concentration within it.
THE TRANSMITTED LASER BEAM IS CLASS 1 (EYE-SAFE) PER IEC 60825.
Senscient ELDS™ is designed for use in the most demanding environments/applications and
provides a sensitive, fast and reliable response. The sophisticated ELDS™ open-path technology
provides immunity to sunlight and minimises the effects of environmental factors such as rain, fog,
ice, snow and condensation.
The Transmitter and Receiver units incorporate heated optics designed to minimise the build-up of
humidity, condensation, snow or ice on the glass lens-windows that could otherwise obscure the
optics in extreme conditions.
Both the Transmitter and the Receiver are microprocessor controlled with advanced self-
diagnostics and fault finding facilities.
Local communication between an operator/technician and the gas detector system is provided via
SITE (Senscient Installation & Test Environment) software running on an industrial computer,
using an RS485 or Bluetooth™ wireless communication link to either the Transmitter or Receiver.
SITE provides the user with a menu-style interface to select and invoke commands for
commissioning and configuring the system; and for viewing the system status and readings.
