Emerson Micro Motion F-Series Sensor- Manuals

□ For best performance, follow Micro Motion recommendations for sensor orientation(see Table 1-3 ). The sensor will work in any orientation as long as the flow tubes remain full of process fluid. Recommended sensor orientation Table 1-3: Liquids Gases Slurries and self-draining applica-tions □ Insta...

2 Mounting Topics covered in this chapter: • Mount the sensor • Attach extended electronics 2.1 Mount the sensor Use your common practices to minimize torque and bending load on process connections. Tip To reduce the risk of condensation or excessive moisture, the conduit opening should not pointupw...

CAUTION! Do not lift the sensor by the electronics or purge connections. Lifting the sensor by theelectronics or purge connections can damage the device. 2.2 Attach extended electronics If you ordered a sensor with extended electronics, you will need to install the extenderonto the sensor case. Note...

3 Wiring Topics covered in this chapter: • Options for wiring • Connect 4-wire cable • Connect 9-wire cable 3.1 Options for wiring The wiring procedure you follow depends on which electronics option you have. See Table 3-1 for the wiring options for each sensor electronics option. Wiring procedures ...

Step 1: Cable preparation Cable layout Run conduit to sensor Metal conduit Wrap the drain wires twice around the shield and cut off the excess drain wires. Micro Motion cable gland Pass the wires through the gland Cable glands Remove the core processor cover Go to Step 2 Go to Step 3 Gland supplier ...

Step 2: Shield termination Assemble the Gland1. Fold the shield or braid back over the clamping insert and 1/8 inch (3 mm) past the O-ring. 2. Install the gland body into the conduit opening on the core processor housing.3. Insert the wires through gland body and tighten the gland nut onto the gland...

Step 3: Terminal connections Connect the wires to the transmitter terminals (see the transmitter manual) Reinstall and tighten the core processor cover Core processor type From Step 1 or 2 Connect the wires to the core processor terminals:Red wire > Terminal 1 (Power supply +) Black wire > Ter...

3. Match the wires color for color. For wiring at the transmitter or remote coreprocessor, refer to the transmitter documentation. 4. Tighten the screws to hold the wires in place. 5. Ensure integrity of gaskets, then tightly close and seal the junction box cover and allhousing covers on the transmi...

4 Grounding The sensor must be grounded according to the standards that are applicable at the site.The customer is responsible for knowing and complying with all applicable standards. Prerequisites Micro Motion suggests the following guides for grounding practices: • In Europe, IEC 79-14 is applicab...

5 Supplementary information Topics covered in this chapter: • Purge the sensor case • Pressure ratings for EN-1092 flanges 5.1 Purge the sensor case If the sensor has purge fittings, they should remain sealed at all times. After a purge plughas been removed, the sensor case should be purged with arg...

4. Connect the supply of nitrogen or argon gas to the inlet purge connection or openinlet purge line. Leave the outlet connection open. • Exercise caution to avoid introducing dirt, moisture, rust, or other contaminantsinto the sensor case. • If the purge gas is heavier than air (such as argon), loc...
