NAUGATUCK, CONNECTICUT – MAY 4, 2015 – In the Oil and Gas Industry, oil fields span miles of remote regions. While field technicians monitor these areas periodically, power loss to important level sensing devices can easily go unnoticed. The U004E Ultrasonic Gap Switch is designed to anticipate such failures. It is equipped with a fail-safe circuit that engages when input power drops under 3 VDC.
The switch is customized to the customer’s desired output in either normally-open or normally-closed states. When the power supply drops, the U004E can open a valve, turn on a pump or send an alarm to alert technicians. While normal instruments can shut off in whatever state they are in during power loss, a fail-safe equipped device can anticipate one of the most common downfalls to a technological world.
Once power is restored to over 12 VDC, the U004E returns to normal operation. The fail-safe circuit serves as an extra mode of protection in applications where the occurrence of power outages can create hazardous spills, fires and other unforeseen industrial disasters. It is important to protect your automated processes as well as your workers, your equipment and your community.
In addition to fail-safe, the U004E also boasts an FM-approved explosion-proof rating in Class I, Div. I, Groups C & D and Class II/III, Groups E, F & G for use in hazardous locations. Its engineered glass to metal seal construction and robust 316 stainless steel or hastelloy c material options make it the perfect candidate for level monitoring in dangerous applications. Additional configuration options are made to order based on customer specifications.
