SIL2 Flow Sensor - Electrical Wiring
The SIL2 sensor housing is manufactured with a ½” NPT electrical conduit connection. The SIL2 sensor
is shipped with a cable gland fitting installed into this NPT connection for use in European applications;
the cable gland fitting is designed for use with cable diameters of 10 mm to 14 mm. For North American
applications, this cable gland fitting can be removed and discarded, and the customer conduit installed
directly into the NPT connection.
The SIL2 sensor electrical connection terminal block is located inside the sensor housing, under the
removable cover. To access the terminal block, remove the five hex-head cap screws that secure the
cover to the housing using a 3 mm hex wrench. Refer to Figures A and B for the location of the cover
screws and electrical terminal block. In order to access the terminal block more easily, as shown in
Figures C and D, the sensor housing may be removed by removing the six mounting screws.
To connect customer wiring to the SIL2 sensor terminal block, insert a screwdriver into the terminal block
to pry open the spring-loaded connectors as shown in Figure E, but use caution not to apply excessive
force. Refer to Figure 1-6 for terminal definition.
Once the wiring connections are secured, re-install the sensor housing and sensor cover; torque the
screws for each to 0.9 N·m / 8 lb.-in. Note that the conduit entry/cable gland fitting may be oriented in 60°
increments from the as-shipped position.
