Can your pressure transmitters withstand being submerged in 20 feet of water? Flood tests Yokogawa EJA/EJX DPharp transmitters.
Wed May 11, 2022
If you're like most plant managers, the words "flood" and "plant" do not go together very well. In a recent turn of events, a local steel plant had to face the fact that their basement had flooded, completely submerging a mix of 50 transmitters. 20 of the instruments were Yokogawa EJA/EJX DPharp transmitters.
The story goes that the steel plant had a large diameter service water line burst which flooded the basement with around 20 feet of water. When the issue was resolved and the basement was given some time to dry, it turned out that all 20 Yokogawa transmitters had completely survived the event. They did not even require calibration adjustments! What happened to the remaining competitor’s brand transmitters, you ask? They were no longer functioning at all and needed to be replaced. Only the Yokogawa transmitters were still working as if nothing had happened.
You might be wondering how this could be possible. After all, floods are no joke and usually result in serious damage to electrical equipment. Yokogawa pressure transmitters are built to withstand even the most extreme conditions, including being submerged in water for extended periods of time. Why? Here is what a representative from Yokogawa had to say:
“Yokogawa designed the EJA/EJX DPharp pressure transmitters with very tight tolerance levels in all aspects of design, production, machining of the parts, and assembly. This is coupled with multiple quality checks along the life of the design and manufacturing cycle of the transmitter. At Yokogawa, we do not design the product to meet the minimum required specifications and in most cases exceed our own published specifications.
When we combine the high-end design, manufacturing, and quality with the advanced technology of the DPharp sensor, the result is an extremely robust product. The one-of-a-kind digital resonating sensor is not prone to hysteresis and its special overpressure design are also considerations in ensuring a non-drifting measurement.
All of this culminates in a pressure transmitter that is not only extremely accurate, but also built to withstand just about anything.”
The customer was in desperate need of replacement transmitters to resume operations. With JMI's extensive field experience and deep understanding of what it takes to solve problems and provide solutions, the plant knew they could count on their JMI sales rep for help. JMI maintains a large stock of inventory and they were able to deliver 30 Yokogawa transmitters on Thanksgiving morning. The plant was able to
resume operations and ultimately decided to replace all the competitor’s pressure transmitters Yokogawa to avoid issues in the future.
If you are searching for reliable and accurate pressure transmitters that can withstand just about anything, contact your local JMI representative to discuss the benefits of Yokogawa EJA110E or EJA530E series.
