 Model 2400S Transmitters with Analog Outputs

Troubleshooting

11.24.3

Drive gain problems

Problems with drive gain can appear in several different forms:

•

Saturated or excessive (near 100%) drive gain 

•

Erratic drive gain (e.g., rapid shifting from positive to negative)

•

Negative drive gain

See Table 11-7 for a list of possible problems and remedies.

11.24.4

Low pickoff voltage

Low pickoff voltage can be caused by several problems. See Table 11-8.

Table 11-7

Drive gain problems, causes, and remedies

Cause

Possible remedy

Excessive slug flow

• See Section 11.17.

Cavitation or flashing

• Increase inlet or back pressure at the sensor.
• If a pump is located upstream from the sensor, increase the distance 

between the pump and sensor.

Plugged flow tube

• Purge the flow tubes.

Mechanical binding of sensor tubes

• Ensure sensor tubes are free to vibrate. Possible problems include:

- Pipe stress. Check for pipe stress and eliminate if present.
- Lateral tube shift due to hammer effect. If this is a possibility, 

contact Micro Motion. See Section 11.3.

- Warped tubes caused by overpressurization. If this is a possibility, 

contact Micro Motion.

Incorrect sensor type configured

• Verify sensor type configuration, then verify sensor characterization. 

See Section 6.2.

Open drive or left pickoff sensor coil

• Contact Micro Motion. See Section 11.3.

Drive board or module failure, cracked flow tube, 
or sensor imbalance

• Contact Micro Motion. See Section 11.3.

Table 11-8

Low pickoff voltage causes and remedies

Cause

Possible remedy

Slug flow

• See Section 11.17.

No tube vibration in sensor

• Check for plugging.

Moisture in the sensor electronics

• Eliminate the moisture in the sensor electronics.

Damaged sensor

• Ensure sensor is free to vibrate (no mechanical binding). 

Possible problems include:
- Pipe stress. Check for pipe stress and eliminate if 

present.

- Lateral tube shift due to hammer effect. If this is a 

possibility, contact Micro Motion. See Section 11.3.

- Warped tubes caused by overpressurization. If this is a 

possibility, contact Micro Motion.

• Test sensor circuitry. See Section 11.25.
• Contact Micro Motion.
