Turbidity and solids content transmitter
CUM 740
Transmitter for optical solids measurement for
turbidity and solids content
The CUM 740 is used for optical solid
matter content measurement in clear
and turbid water and in sludge.
The transmitter covers a wide range of
meauring sensors from low to high solids
concentrations.
Applications
• Closed sewage treatment plant areas
such as inflow, preclarifier, and sludge
removal
• Process monitoring in hightemperature and hazardous areas
in the chemical industry, waste
incenerators and steam generation
plants
Features and benefits
• Large selection of sensors for fourbeam pulsed light systems
• Large two line LCD for set up and
measured value display
• Large LED display for separate
measured value display
• Large concentration range from
2 FNU to 150 ppm (150 g/l)
• Measuring units in ppm, g/l, mg/l,
TEF, %
• Menu controlled set up and calibration
in plain text
• Measured value processing is done
in the sensor, giving low transmission
sensitivity
• Five relay outputs (sensor cleaning,
error message, two configurable
limit relays, Hold)
• Battery-powered measured value
storage
• One or two channel versions
The Power of Know How
Measuring system
The complete measuring system
consists of:
• Turbidity transmitter CUM 740
• Turbidity sensor, e.g. TurbiMax W
CUS 65 with measuring cable
• Sensor installation holder or
immersion assembly

Measuring principle
Signal processing
Measured value preprocessing takes
place in the sensor electronics. The
connectable sensors operate using the
four-beam pulsed light method. Depending on the sensor version connected,
turbidity is determined by different optical
measuring methods:
• Absorption light method
• Backscatter light method
• 90° scattered light method
Turbidity sensors
Endress+Hauser offers the following
turbidity sensors for connection to the
CUM 740 transmitter:
• CUS 31, 90° scattered light method,
measuring range of 0.00 to 9999 FNU,
0.0 to 300 ppm (g/l), 0.0 to 200.%
concentration
• CUS 41, 90° scattered light method,
measuring range of 0.00 to 9999 FNU,
0.0 to 300 ppm (g/l), 0.0 to 200.0%
concentration
2
The sensor generates a turbidity or
solids concentration signal which is
converted into a frequency signal. the
frequency signals are assigned to
corresponding turbidity units and solids
concentration content, and are indicated
on the transmitter display.
• CUS 65 - A, absorption light method,
measuring range 0 to 12 ppm (g/l)
• CUS 65 - B, absorption light method,
measuring range 0 to 40 ppm (g/l)
• CUS 65 - C, absorption light method,
measuring range 0 to 50 ppm (g/l)
• CUS 65 - D, 90° scattered light
method, measuring range 1 to
1000 FNU
• CUS 65 - E, backscattered light
method, measuring range 10 to
150 ppm (g/l)
The CUM 740 is fully set up and
calibrated in a menu-assisted software
using a dirt-proof membrane keypad.
The operator is guided interactively
through the operating muen. The
interface is a two-line plain text display.
Operation
1
Programming levels which go beyond
everyday operation processes are only
accessible by entering a password.
All the calibration data and parameters
are retained if there is a power failure or
when the device is shut down (nonvolatile RAM).
