Black Knight and Red Fox: Cleared for Outdoor Duty

Ingress Protection testing is the process associated with determining the level of protection an enclosure provides against the elements. These intrusions can be many things including water, dust and other foreign objects. The IP Code, also known as the International Protection Marking, rates the degree of protection an enclosure provides. The IP Code has two digits. The first digit identifies the level of  protection from solid particles and the second digit indicates how much protection is provided against liquids.

Recently, a regulatory compliance lab completed Ingress Protection testing for two popular BJE liquid level gauges: Black Knight and Red Fox. Both of the units earned the rating IP53, certifying the internal mechanisms of these gauges are protected from dust and sprayed water. That means both of these gauges are now cleared for use in outdoor applications.

“The tests revealed no water entered the housing of Black Knight or Red Fox units when sprayed at angles up to 60 degrees, like that of a sustained rain storm,” said BJE Project Engineer Paul Pitney. “After eight hours of ‘dust storm’ exposure testing, the Black Knight experienced minimal dust incursion. It was significantly less than the IP standard allows and definitely not enough to interfere with the Black Knight’s operation.”

Recent design modifications fully enclosed the mechanism housing for both gauges. BJE engineers submitted the redesigned units for Ingress Protection testing to verify atmospheric elements like dust or rain would not interfere with their operation. The Black Knight mechanically measures decreases in levels of oil, waste oil, diesel fuel, antifreeze and other fluids with a high flash point in tanks up to 99 inches deep. The Red Fox keeps track of tanks with similar liquids when they are being filled up.
