Expert Maintenance Tips

1. Verify Model and Range Compatibility Prior to Installation

The EDS3300 series offers multiple range options (1–40 bar). Confirm that the range indicated in the model code (e.g., 0016 = 16 bar, 0010 = 10 bar) covers the system operating pressure. For optimal accuracy and service life, it is recommended that maximum operating pressure not exceed 80% of the full scale.

2. Correct Installation Torque and Sealing

The EDS3300 series features G1/4 A ISO 1179-2 external thread pressure connections. Use a torque wrench during installation—recommended torque is 20 N·m (15 lbf·ft) . Use OEM-specification O-rings for sealing—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 sensor diaphragm.

3. Electrical Connection Precautions

• EDS3346-1-0016-Y00-F1: Features M12×1 / 4-pin electrical connection

• EDS3346-3-0010-000F1: Features M12×1 / 4-pin electrical connection

• EDS3348-5-0010-000-E1: Features M12×1 / 5-pin electrical connection

• Supply voltage is 18–35 V DC

• Observe correct polarity—reverse connection may damage the device

4. Programming and Parameter Setting

• Menu navigation via membrane keypad

• Switching points and reset points can be independently set

• Supports switch delay time setting

• Output function selectable between N/O (normally open) or N/C (normally closed) 

• Display units (bar/psi/MPa) can be freely switched via the menu

5. Display Rotation and Mounting Orientation

The EDS3300 series features a display that can be rotated in two planes—after installation, the display can be adjusted to the optimal viewing position. The device can be mounted in virtually any orientation without additional mechanical adapters.

6. Periodic Calibration and Functional Checks

Perform calibration checks every 12 months or according to system criticality to verify that the deviation between displayed value and actual pressure remains within specification (≤±0.5% FS typical). The EDS3300 series offers excellent long-term stability. If abnormal signal drift or display anomalies are observed, arrange for servicing or replacement.
