Level switch
•
function 1 monitors minimal and maximal level depth, for example in fi re engine cars, tanks etc.
•
function 2 monitors level depth in water collectors, basins, pools etc.
•
selection of particular function is made by jumper on the front panel
•
level depth is indicated on the panel of device by LED
•
device monitors 5 levels by using six probes (one probe is common)
•
common probe can be replaced by a metal (conductive) tank
•
level indicationby six LED‘s on the front panel of the device
•
it is possible to connect another indication module (e.g. in fi re-engine cabin)
•
adjustable sensitivity according to liquid conductvity
•
adjustable time delay - elimination of level movement, e.g. while a tank is being fi lled up
•
measuring frequency 10 Hz to prevent polarization of liquid
•
supply voltage 12.. 24 V DC (to be used in fi re-engines) or galvanically separated 230 V AC for general use
•
contact relay 10 A for signalization of full / empty tank (according to a chosen function)
•
choice of functions PUMP UP / OFF / PUMP DOWN by a switch located on the front panel of the device
•
protection degree IP65
