Installation and User Guide
Unlike mechanical gages, the 628-13-GH-P1-E1-S5 pressure transmitter outputs an electrical signal. Therefore, it requires proper electrical wiring in addition to the standard pressure connection. The basic procedure is as follows:
-
Inspect the transmitter prior to installation to ensure the enclosure and process connection threads are intact and free of dents.
-
Mount the transmitter into the liquid pressure measurement point via the process connection thread. Tighten appropriately using a suitable tool; avoid applying excessive manual force which can damage the threads.
-
Connect the 10-30 VDC power supply to the power terminals strictly following the wiring diagram provided in the accompanying technical manual.
-
Wire the output signal (4-20mA or 0-10VDC depending on the ordered configuration) back to the controller, PLC, or BMS. Pay close attention to correct polarity and select an appropriate wire gauge suitable for the signal transmission distance.
-
Power up the transmitter and verify the output signal using a multimeter or the monitoring software of the control system to confirm correct operation.
-
Cross-reference the readings with the actual pressure at the measurement point (if a reference master gauge is available) to validate accuracy, and recalibrate if necessary according to the manufacturer’s guidelines.
-
Record the installation parameters and include them in your routine maintenance plan to ensure signal stability throughout its operating lifetime.
Note: The transmitter features a NEMA 4X (IP66) enclosure rating, making it suitable for wet environments. However, ensure that all electrical cable glands and conduits are sealed properly to maintain this ingress protection rating.
Practical Applications
-
Monitoring water pressure in pumping stations, water supply networks, and drainage systems.
