BS EN 50227-1999

控制线路装置和开关元件临近直流感应器.临近感应器和开关放大器接口(NAMUR)

Steuergeraete und Schaltelemente Naeherungssensoren Gleichstrom-Schnittstelle fuer Naeherungssensoren und Schaltverstaerker (NAMUR) Control Circuit Devices and Switching Elements Proximity Sensors,d.c. Interface for Proximity Sensors and Switching Amplifiers (NAMUR) Appareils et elements de commutation pour circuit de commande,interface DC pour capteurs de proximite et amplificateurs de commutation (NAMUR)

适用范围:This standard applies to proximity sensors connected for operation by a two-wire connecting conductor to the control input of a switching amplifier. The switching amplifier contains a d.c. source to supply the control circuit and is controlled by the variable internal resistance of the proximity sensor. NOTE 1 These devices can be used in an explosive atmosphere if they also comply with EN 50020, Electrical equipment for explosive atmospheres, intrinsic safety "i". NOTE 2 These devices have been defined by the German organization "Normenausschuβ fur Meβ-und Regelungstechnik (NAMUR)".
