description
a compact,self contained ultrasonic iquid level switch with 316 stainless steel wetted parts and 240v switching capability.squitch is a '2 wire' product-that is,it requires only 2 electrical connections,using standard instrument wire.
the squitch is connected in series with the load (contactor,starter,relay,etc.) and acts as a simple swithc,operated by liquid presence.
squitch may also be interfaced directly to a plc using simple instrument cable.for this purpose,a plc terminal is provided in the housing.
options
squitch is available with a wide variety of mounting options including threads,flanges and hygienic couplings.see ordering informatioon overleaf for full details.
operation
squitch may be set on site with a selector switch to energise on either wet or dry.
when squitch is off a small current of less than 4.5ma is drawn through the load and a red led viewed through a window in the end cover will flash approximately onceper second.
when squitch ison,the full load current(0.5a max.) flows,ａnd the l.e.d is on constantly.in this way there is always an indication that squitch isalive and well.
squitch may be installed in any position in the vessel.
