Dwyer 628-90-GH-P1-E1-S5 Pressure Transmitter – Accurate and Durable Pressure Measurement Solution
Posted on: 16/07/2026
Alongside the 628-13 model, Dwyer's Series 628 offers various process connection options and measurement ranges to fit specific mounting locations within a system. The 628-90-GH-P1-E1-S5 pressure transmitter is a prominent choice among M&E engineers when high durability and a stable output signal are required for automated monitoring systems.
Introduction to the 628-90-GH-P1-E1-S5 Transmitter
The 628-90-GH-P1-E1-S5 belongs to Dwyer's Series 626 & 628. It is an industrial pressure transmitter that outputs standard electrical signals and is fabricated from 316L stainless steel (SS) to ensure corrosion resistance and mechanical strength under continuous operational environments. The product is UL-certified, meeting strict safety standards for industrial and building systems.
Technical Specifications
Installation and User Guide
The installation procedure for the 628-90-GH-P1-E1-S5 pressure transmitter is similar to other models in the Series 628, consisting of mechanical process connection and electrical wiring (power supply, output signal):
-
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 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 voltage 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 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 pressure in chiller systems and industrial water pumps.
-
Connecting pressure signals to central control panels and BMS networks.
-
Measuring pressure in water treatment installations and fire protection systems (fire pumps).
-
Integrating into industrial manufacturing lines requiring high reliability.
