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.
Before using these radar sensors, please study
• Section 2, Cautionary Statements
• Section 3, Initial Inspection
• Section 4, Quickstart
2. Cautionary Statements
• Follow country-specific installation standards, prevailing safety
regulations, accident prevention rules, and this manual’s safety
instructions.
• 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, consult with a
Campbell Scientific applications engineer.
• 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.
