3.4.5 Remote Mounting Applications
Some sensor mounting applications require that the gas sensor head be remotely mounted away from the sensor trans-
mitter. This is usually true in instances where the gas sensor head must be mounted in a location that is diff icult to
access. Such a location creates problems for maintenance and calibration activities. Detcon provides the Model Series
400IS in a remote-mount conf iguration in which the sensor and the transmitter are provided in their own condulet
housing and are interfaced together with a four conductor cable. Reference f igure 4 for wiring diagram.
