Expert Maintenance Tips

1. Verify Model and Range Compatibility Prior to Installation

• MBC5100-2431-1DB04 / 061B510366: Regulation range 1–10 bar, max working pressure 150 bar—do not use in systems exceeding 150 bar

• 060G1476: Range 0–6 bar, overload pressure 20 bar—confirm system operating pressure does not exceed 6 bar

2. Correct Installation Torque and Sealing

The MBC 5100 series features G1/4″ female with flange (ISO 228-1) pressure connections. The MBS 3350 series features G1/2″ male (EN 837) 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

• MBC5100-2431-1DB04: Features DIN plug Pg11 (EN 175301-803-A) , SPDT contacts, contact rating AC15=0.5A/250V, DC13=12W/125V

• 061B510366: Features DIN plug Pg11, SPDT contacts

• 060G1476: Features Angular connector Pg11 (EN 175301-803-A) , supply pin Pin 1, common Pin 2

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

4. Mounting Position and Vibration Protection

Both MBC 5100 and MBS 3350 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.

5. Temperature Effects

The MBC 5100 series ambient temperature range is -40°C to +85°C. The MBS 3350 series compensated temperature range is 0°C to +100°C. Under extreme temperature conditions, perform zero-point calibration during system commissioning to eliminate measurement deviations caused by installation location temperature variations.

6. Periodic Calibration and Functional Checks

• MBC 5100: Perform functional checks every 2,000 operating hours or annually to verify switching point accuracy and contact reliability

• MBS 3350: 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.
