HRH-6/AC | Level Switch

• Function 1 monitors minimal and maximal level depth, for example in fire engine water tanks, etc.
• Function 2 monitors level depth in water collectors, basins, pools, etc.
• The selection of a particular function is made by the jumper on the front panel.
• the level is indicated on the instrument panel
• The device monitors 5 levels by using six probes (one probe is common).
• A common probe can be replaced by a metal (conductive) tank.
• Level indication six LED‘s on the front panel of the device.
• It is possible to connect another indication module (e.g. in the fire-engine cabin).
• Adjustable sensitivity according to liquid conductivity.
• Adjustable time delay - elimination of level movement, e.g. while a tank is being filled up.
• Measuring frequency 10Hz to prevent polarization of liquid.
• Supply voltage 12.. 24V DC (to be used in fire-engines) or galvanically separated 230V AC for general use.
• Contact relay 10A 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.
