The transmitter includes a lens and a connection for the optical
fibre located in the focal plane of the lens. The receiver contains
a lens and the sensor electronics. The sensor electronics consist
of the detector module and the sensor card. The powering of the
sensor electronics is performed with a twisted pair copper cable
delivering 24 VDC. The detector card is a detector with pre-ampli-
fier, and the sensor card consists of driver electronics for the opti-
cal return signal and DC/DC-converter.
The laser light is coupled from the optical fibre in the transmitter
to its lens and passes through a wedge tube (for protection of the
lens) and then through the measurement volume. The lens in
the receiver (also protected with a wedge module) focuses the
incoming laser light on the detector where it is converted to an
electrical signal. This signal is amplified and converted to an opti-
cal signal and returned to the central unit. The mounting of the
sensor requires a flange with the dimensions DN65/PN6 or ANSI
4"/150 lbf.
4.1.4 The CD 6C Ex Sensor
Each measurement channel is available in this ATEX version for
measurements in explosive areas. The CD 6C Ex sensor is used
for measurements in these kind of measurements. In this ATEX
version the CD 6C Ex sensor is used. For this set-up a barrier box
