Few things are as ubiquitous in the process control industry as the need to measure the level of a process material in a container. Whether that material is water, waste water, petroleum, sugar, or any other form of liquid or solid, level measurement accuracy can be a determining factor in both profit margins and safety. On December 11th 2005, malfunctioning level gauges were partially responsible for a massive explosion at the Hertfordshire Oil Storage Terminal in Hertfordshire, England. According to the Health and Safety Executive that investigated the blast, "the tank was full, but gauges and safety devices did not work."1 A high level switch that should have detected the petrol level and cut off flow to the tank failed to operate and workers didn't notice that the tank was overflowing.2 This resulted in a 32-hour inferno which injured 43 people and left many families homeless.
The Helios Large Display and Controller is now UL and C-UL approved. With its NEMA 4X, IP65 rating, it can operate in the harshest of weather conditions like rain, snow and sleet. It can also withstand windblown materials such as dust, lint, fibers, and dirt. Not only is the Helios well protected from the elements, but is has a whopping 1.8 inch display with super-luminous LEDs readable from up to 100 feet away. This makes it ideal for outdoor applications in bright sunlight. Learn more about the Helios Series.
Did you know the The ProVu, Helios, and ProtEX-MAX all do the same thing? Yes. In fact, they all program the same way using Meterview Pro USB software, have the same inputs and outputs, and all can be used for the same applications. So, whatever your need – a panel meter for a control room, a large display meter for reading from far away in bright sunlight, or an explosion-proof meter for a hazardous area, Precision Digital can provide you with the right display and controller for your application. See more details on how the ProVu, Helios, and ProtEX-MAX families are alike.
One of the most powerful features of the ProVu is its ability to power a 24 VDC powered transmitter. This makes for easy wiring, and lower cost installations, by eliminating the need for an external 24 VDC power supply. Most ProVu models come standard with this 24 VDC supply. Learn how to use this supply in this short, 1 minute video.
