Expert Maintenance Tips

1. Verify Model and Range Compatibility Prior to Installation

• MBC5000-1011-1CB04: Regulation range -0.2–1 bar, max working pressure 15 bar—do not use in systems exceeding 15 bar

• 064G1118 / 060G3628: Both have 0–250 bar range—confirm system operating pressure does not exceed 250 bar

2. Correct Installation Torque and Sealing

The MBC 5000 series features G1/4″ female thread (ISO 228-1) pressure connections. The MBS 3050 series features G1/4″ male thread (DIN 3852-E) pressure connections with hex size 27 mm. Use a torque wrench during installation to the torque value specified in Danfoss technical manuals. Use OEM-specification O-rings or bonded sealing washers—PTFE tape must not be used (it may block internal sensor passages). Ensure piping is clean prior to installation to prevent debris from damaging the sensing element.

3. Electrical Connection Precautions

• MBC5000-1011-1CB04: Features PG11 plug (DIN 43650 A / EN 175301-803-A) , SPDT contacts, contact rating AC15=0.5A/250V, DC13=12W/125V

• 060G3628: Features M12×1 / 4-pin electrical connection, supply pin Pin 1, common Pin 4

• Verify load current and voltage do not exceed contact ratings prior to wiring

4. Pulse Snubber Maintenance (MBS 8250)

The MBS 8250 series is equipped with an integrated pulse snubber. Over extended service, the snubber may become partially blocked by fine particles in the medium. Periodically check transmitter response time—if significantly slower response is observed, the pulse snubber may require cleaning or replacement.

5. Mounting Position and Vibration Protection

Both MBC 5000 and MBS series offer excellent vibration stability and can be mounted in any orientation. For extreme vibration applications, mechanical decoupling via flexible pressure hose connection is recommended.

6. Temperature Effects

The MBC 5000 series ambient temperature range is -40°C to +85°C. The MBS 3050 series compensated temperature range is 0°C to +80°C. Under extreme temperature conditions, perform zero-point calibration during system commissioning to eliminate measurement deviations caused by installation location temperature variations.

7. Periodic Calibration and Functional Checks

• MBC 5000: Perform functional checks every 2,000 operating hours or annually to verify switching point accuracy and contact reliability

• MBS 8250 / MBS 3050: Perform calibration checks every 12 months to verify that output signal vs. pressure correspondence remains within specification (≤±0.5% FS typical). If abnormal signal drift or output anomalies are observed, arrange for servicing or replacement.
