connections. See the wiring diagram in Figure 30 and refer to Table 10 and Table 11 for wire
sizes and lengths. Following are three remote sensor configurations and wiring diagrams.
Care must be taken when making up gas fittings on the sensor when mounted on a remote
bracket as shown in Figure 24 below. A backing wrench must always be used (in particular for
VCR connections) when connecting the gas sample line to the sensor. The inlet fitting, although
epoxied, is very delicate and the seal can easily be damaged if it is allowed to spin as the
connection is tightened. A 0.010 inch orifice is included with 0-50ppm sensors and must be
installed at the sensor inlet in order to control gas flow.
Contact Servomex for additional information on remote sensor installations.
