Hose continuity tester from Newson-Gale
29 May 2013
The OhmGuard system ensures hoses do not pose an electrostatic ignition risk in potentially combustible atmospheres.
It is important to ensure hoses exposed to ignition hazards caused by static electricity are grounded.
The OhmGuard tester is designed to ensure that a string of assembled hoses have good electrical continuity so that the metal components of a hose cannot accumulate electrostatic charges.
The device operates on the principle of ‘Pass’ or ‘Fail’ test procedure; to operate, a driver must ground the truck and then assemble the required number of hose sections to the truck.
The OhmGuard clamp is then connected to the free coupling or nozzle, if the electrical resistance is ‘good’, a green light will pulse to inform the driver that the hose is safe to use.
If there is a break in the continuity, the LED will not pulse and the driver should inspect each part of the hose.
The OhmGuard carries cCSAus, ATEX and IECEx approvals for operation in the highest combustible gas, vapour and dust atmospheres.
