4 Determining a Location Figure 3 T-Series sensor with junction box Step 1 Determining a Location Choose a location for the sensor based on the requirements described in this section. The following general guidelines can help you select an appropriate location for the sensor. Full flow tubes For opt...

5 Determining a Location Figure 4 T-Series sensor ambient and process temperature limits Hazardous area approvals may impose additional limits on ambient and process temperature. For the ATEX “T” rating, refer to the ATEX documentation shipped with the sensor or available on the Micro Motion web sit...

6 Determining a Location Maximum wiring distances If the transmitter is mounted remotely from the sensor, the maximum distance between the sensor and transmitter depends on cable type. See Table 2. Pipe run Micro Motion sensors do not require a straight run of pipe upstream or downstream. Valves Aft...

7 Orienting the Sensor Step 2 Orienting the Sensor The sensor will function properly in any orientation if the sensor tubes remain filled with process fluid. Micro Motion recommends orienting the sensor in a vertical pipeline, with process fluid flowing upward through the sensor (see Figure 5). Figu...

8 Orienting the Sensor Figure 6 Eccentric reducer • The gap between the electronics housing and sensor body should be inspected periodically. Manually clean this gap when necessary. • The ASME Bioprocess Equipment Standard (ASME BPE-1997), section SC-3.12.1, includes recommendations regarding how to...

9 Mounting the Sensor Step 3 Mounting the Sensor Use your common practices to minimize torque and bending load on process connections. 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 ...

10 Wiring Step 4 Wiring Hazardous area installations If you are installing the sensor in a hazardous location, verify that the hazardous classification information printed on the sensor tag matches the environment in which the sensor will be installed. Failure to comply with the requirements for int...

11 Wiring Figure 8 Micro Motion cable gland and heat shrink 4. For connection at the core processor housing, prepare shielded cable as follows (for armored cable, omit steps d, e, f, and g): a. Strip 4 1/2 inches (114 mm) of cable jacket. b. Remove the clear wrap that is inside the cable jacket, and...

12 Wiring Figure 10 Applying the heat shrink g. Position gland clamping insert so the interior end is flush with the heat shrink. h. Fold the cloth shield or braid and drain wires over the clamping insert and approximately 1/8 inch (3 mm) past the O-ring. Figure 11 Folding the cloth shield i. Instal...

13 Wiring Figure 13 Connecting the wires at the core processor 7. Reinstall and tighten the core processor housing cover. 8. Additional wiring instructions for the transmitter can be found in the transmitter manual. Note: Never ground the 4-wire cable shield and shield drain wire(s) at the transmitt...

14 Grounding Step 5 Grounding The sensor can be grounded via the piping if the joints in the pipeline are ground-bonded. If the sensor is not grounded via the piping, connect a ground wire to the internal or external grounding screw, which is located on the core processor housing or junction box. Im...

15 Purge Fittings 4. Connect the supply of nitrogen or argon gas to the inlet purge connection or open inlet purge line. Leave the outlet connection open. • Exercise caution to avoid introducing dirt, moisture, rust, or other contaminants into the sensor case. • If the purge gas is heavier than air ...

16 Return Policy Return Policy Micro Motion procedures must be followed when returning equipment. These procedures ensure legal compliance with government transportation agencies and help provide a safe working environment for Micro Motion employees. Failure to follow Micro Motion procedures will re...
