Level switch that monitors minimal and maximal level depth, for example in fire engine cars, tanks etc.

Another important function monitors level depth in water collectors, basins, pools etc.

Main features

• 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 indication by 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.

Technical specifications:

• 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.

Level relay probes and recommended wires:

• SHR-1-M - level probe with brass electrode
• SHR-1-N - level probe with stainless steel electrode
• SHR-2 - level probe with stainless steel electrode embedded in PVC cover
• SHR-3 - conductivity pressure level probe
• conductor D05V-K 0,75/3,2 - conductor 1x 0,75 mm² with certificate for drinking water
• kabel D03VV-F 3x0,75 / 3,2 - 3x0,75 mm² cable with drinking water certificate
