Safety requirements
Prior to installation and use, it is necessary to read and understand this
instruction manual with additional attention to Ex marking, special conditions
of use and technical parameters.
The device can be connected only to equipment with proper, fitted
intrinsically safe parameters. It is strongly recommended to carry out any
service manipulations without presence of explosion atmosphere or outside of
explosion endangered zone.
Description
9415-x0001-xx Radar Sensor is an intrinsically safe telemetry device designed for measuring liquid level in a tank. The device is mounted on the top of the tank with the use of a special glued or threaded adapter. As a sensor of fluid level radar chip is used. Information related to the measured level is presented on an LCD and can be read via 2,4 GHz radio interface. The device is powered by two non-replaceable lithium primary cells or from an external cable connection. All components are located on one printed board inside of a plastic enclosure. The version with primary cells has no external connectors. The second version has a permanently connected cable with two circuits – power supply and for 0…5V analog signal output.
