Description Platon Infra-Red Flow Alarm | DS1120 Specification Sensor Type IR Beam break detection Direction Logic Position of float above/below sensor established on first detection of float after power up Setting Position Held by spring clip anywhere in flow tube operating range Temperature -5 to 50?C Environment IP44 with cable exit downwards Dimensions 22 x 66 x 30 (HxWxD) 5mm space needed behind frame. Spacer provided Sensor Cable 2m, 3 core screened Cable Functions Red – positive Black – OV common White – Transistor output Voltage Supply 12V nominal, 8V – 26VDC range at 25mA Output (Sensor Positioned with Cable Exit Down) Open circuit for low flow alarm, conducts for flow above switch point Switch Points For falling float, top edge of float at centre line of sensor. For rising float, switching occurs when base of float passes centre line Compatibility Frames All standard GIR sensors are supplied with a fitting kit suitable for use on Platon NG, LG, NGX, or LGX style frames. The sensor can be supplied and fitted within Platon GU or SGUV style housings. Flow Fluid GIR sensors are supplied set up for the flow tube size specified and either liquid or gas as the flowing medium. The sensors are not normally interchangeable between different-sized flow tubes. Flow Scales For size 1 and 2 flow tubes, the flow scale artwork serial number (eg CA 141002) must be issue C or later (first digit). Otherwise, the scale marks may interfere with the infra-red beam. For size 3 flow tubes, GIR sensors will work correctly on all previously supplied scale artworks. Consult the sales office and specify flow tube and alarm sensor module together.
