6.6 Remote Mounting Applications
Some sensor mounting applications require that the gas sensor head be remotely mounted away from the
sensor transmitter. This is usually true in instances where the gas sensor head must be mounted in a location
that is difficult to access. Such a location creates problems for maintenance and calibration activities. Detcon
provides the DM-534C sensor in a remote-mount configuration in which the sensor (Model DM-534C-RS) and
the transmitter (Model DM-534C-RT) are provided in their own condulet housing and are interfaced together
with a three conductor cable. Reference figure Figure 9 below for wiring diagram.
