1. Thank you for choosing a NIVELCO instrument SN We are sure that you will be satisfied throughout its use Quiveleo DUE ee SEAT KZA Series R 300 Vibrating fork level switches 1 APPLICATION NIVOSWITCH R 300 series vibrating forks are for level detection of powder lumpy solids and granules Overfilling and emptying of silos or vessels can be prevented when using them as high or low fail safe switches The RC series basic type insertion lenght 125 mm with casted forks are recommended for small granules while the RL series basic type insertion lenght 137 mm with welded forks are recommended for larger granules Both RC and RL series are also available in dust Ex versions 2 TECHNICAL DATA 2 1 GENERAL DATA TYPE Medium pressure Insertion length Material of wetted parts Medium temperature Ambient temperature Medium USER S MANUAL ROO 300 0 40 bar 6 bar with PP flange See Derating diagram p 0 125 3m Casted fork DIN 1 4404 welded fork DIN 1 4571 i 40 C 130 C See Derating diagram rr 40 C 70 C See Derating diagram f p 20 01 kg dm 0 5 sec Getting immersed Switching delay f lt 1 s selected high density H 0 5 kg dm Getting free lt 3 s selected high density L p lt 0 5 kg dm Indication of operation Bi colour LED i y Test of operation Output state can be changed with test magnet U f 2 2 TWO WIRE DC VERSION i TYPE 22.
