CS475, CS476, and CS477 Radar Water
Level Sensor
1. Introduction
The CS475, CS476, and CS477 are radar-ranging sensors that monitor the
water level of rivers, lakes, tidal seas, and reservoirs. They output a digital
SDI-12 signal to indicate distance and stage. Many of our dataloggers can read
the SDI-12 signal.
This manual provides information only for CRBasic dataloggers.
It is also compatible with most of our retired Edlog dataloggers.
For Edlog datalogger support, see an older manual at
www.campbellsci.com/old-manuals .
2. Precautions
• READ AND UNDERSTAND the Safety section at the front of this
manual.
• Follow country-specific installation standards, prevailing safety
regulations, accident prevention rules, and this manual’s safety
instructions. The sensor is designed for safe operation in accordance with
the current technical, safety, and ANSI standards.
• Depending on the model, the emitting frequencies of these radar sensors
are either in the C or K band range. Their low transmitting power is well
below the internationally permitted limits. When used correctly, the radar
sensors present no danger to people.
• Do not attempt to install the sensor unless you are qualified to perform the
installation.
•
Care should be taken when opening the shipping package to not damage or
cut the cable jacket. If damage to the cable is suspected, contact Campbell
Scientific.
•
Handle the sensor carefully, since it is a precision instrument.
•
Since the sensor is commonly installed over water from tall structures, use
appropriate safety equipment such as a safety harness or a life preserver
when installing or performing maintenance on the sensor.
•
It is the responsibility of the user to ensure that the sensors are maintained
and functioning properly.
• The sensor is designed for safe operations in accordance with the current
technical, safety, and ANSI standards.
