Connecting cable with electric isolation

4.2.1
A connecting cable with an electrical isolator integrated into the connector
is available as an accessory. The cable is 5 metres long and is used for
the galvanic isolation of the sensor output to the electronics to which it is
attached. The cable is delivered with an appropriate connector for the
mass flow sensor on one side and with open cable ends on the other side.

Replacement sensor

4.2.2
The replacement sensor serves as a replacement in case of damage to or
loss of the original mass flow sensor.

• ISO certificate
An ISO certificate from the manufacturer documents six measuring points
including the measuring conditions.

When ordering a new sensor, please indicate the certificate
number of the old sensor in order to take account of
customer-specific measuring conditions directly during
calibration.
