Resistance limit switch SPRS2I-M-220 ??2.838.001-05

designed to monitor the resistance value of resistive (electrode) sensors and to provide information on the output of resistance value beyond the established limits, installed in products of III order of execution group C3 according to GOST 52931 at nuclear power facilities - NPP, ATEC, AST. In a set with electrode level sensors type C57, TU269, SUED, SUE-DAS can be used as signalling devices-regulators of liquid media level from electrolytes to distilled water in technological equipment installed in explosive zones of all classes. The sensors are connected to the signallers by means of a communication line. The signallers are designed for installation outside the hazardous areas of premises and outdoor installations.
