Remote mount design

For devices with a remote mount design, the transmitter and sensor are mounted in separate locations. The
electrical connection between the transmitter and the sensor is provided by a signal cable.
When the minimum conductivity of the measuring medium is 5 µS/cm, a maximum signal cable length of 50 m
(164 ft) is possible without fitting an additional preamplifier to the sensor. With a pre-amplifier, the maximum
permissible signal cable length is 200 m (656 ft).
The transmitter is available in two housing designs:
• Single-compartment housing:
On the single-compartment housing, the electronics area and the connection area in the transmitter are not
separated from each other.
• Dual-compartment housing:
On the dual-compartment housing, the electronics area and the connection area in the transmitter are separated
from each other.
ProcessMaster
The ProcessMaster sensor is available in two designs, which are distinguished by the design level.
