CBS100.1-2 and CBS105.1-2

If the Smart Lambda Sensor Cables CBS100.1-2 and CBS105.1-2 are supplied
with DC voltage, it can be configured whether the output signal is a function
either of the oxygen content or the lambda value of the gas or the pump current
of the sensor.

CBS104.1-2

Together with an LSU4.9 lambda sensor, the CBS104.1-2 Smart Lambda Sen

-

sor Cable emulates an LSM11 discrete-level sensor. With connected LSU4.9
lambda sensor, the signal of an LSM11 discrete-level sensor in the range of -
20 mV to +80 mV is exactly replicated by the analog signal at the cable output.
In the process, the emulation of the LSM11 discrete-level sensor with the
LSU4.9 broadband sensor supplies significantly more reliable measuring
results on the lean scale than the original LSM11 discrete-level sensor. LSM11
discrete-level sensors in use can simply be replaced electrically and mechani

Properties

Properties of the CBS10x.1-2 Smart Lambda Sensor Cables:

• Integrated control of the heater of the lambda sensor
• Galvanic isolation of analog output from the supply voltage
• Selectable measure variable (CBS100.1-2 and CBS105.1-2; only with

supply of DC voltage)

Output signal and measure variables

The complete technical data of the CBS10x.1-2 Smart Lambda Sensor Cables
are located in the chapter “Technical Data” on page 25.
