Mounting the Sensor

Step 3 Mounting the Sensor

Use your common practices to minimize torque and bending load on process connections. Figure 7 illustrates how to mount the sensor. To reduce the risk of condensation or excessive moisture, the conduit opening should not point upward (if possible). The conduit opening of the junction box or core processor can be rotated freely to facilitate wiring.

The CMF010 sensor has an optional mounting configuration (Figure 8) for use with small or soft pipeline.

Figure 8 Optional mounting for CMF010 sensors

If the pipeline will not support the sensor, mount the sensor using bolts as illustrated.

2 × user supplied bolts

5/16(M8) maximum diameter

2 1/4(58 mm) minimum length

Junction box or core processor (junction box shown)

Junction box can be rotated by hand (before wiring is attached) for access to mounting holes

Core processor does not need to be rotated for access to mounting holes

If necessary, rigid standoffs (e.g., steel washers) can be installed

Mounting surface — if pipe supports are used, they should be rigidly supported by the same mounting surface that supports the sensor
