OLE Z5020 ATEX Tank Level Gauge with Alarm
The OLE Z5020 ATEX Tank level gauge is an accurate continuous-reading tank gauge with local alarm functions and an array of outputs suitable for low-flashpoint fuels. It is designed for monitoring the levels of hazardous liquids such as kerosene or petrol stored in vented tanks.
Suitable for tanks up to 3m deep, an Ex-rated level sensor is installed through the top of the storage tank using a 1" BSPT gland entry.
In order to comply with ATEX certification, the Z5020 display is to be installed within a safe area and is to be connected to the intrinsically safe sensors via the integral barriers.
Using the hydrostatic principle, the backlit display gives a constant reading of the tank contents, which is within ± 0.25% accuracy.
In addition, the Z5020 tank gauge features 4 software-programmable level alarm outputs.
