CYLINDRICAL INDUCTIVE ATEX SENSORS IN METAL HOUSING ANALOGUE LINEAR OUTPUT 4 ÷ 20 mA • ATEX certified II 1GD for zone 0;20 • Cable output • Housing B-2 General features: These inductive proximity sensors provide an output current inversely or directly proportional to the distance between sensing face and metal target. The output current is dependent also on the target material. So the proximity sensors in addition to determining distance, displacements, vibrations and distortions can be used to recognize the composition of metal and alloys. The current flowing through the load RL, generates a variation in voltage across the resistor for a suitable value of RL, it is possible to obtain voltage variations from one tenth to 20 V as can be seen in the tables. Technical data: Connections brown Safety parameters: Measurement range Cable diameter Use in hazardous area according to instruction manuals Max switching frequency ( f ) These sensors must be used in conjunction with associated apparatus (See Sect. E) No- load supply current Maximum linearity error Flush mounting Non flush mounting • Cable: 2 m PVC CEI 20 - 22 II; 90°C; 300 V; O.R. • Housing: nickel plated brass • Sensing face: plastic Supply voltage: 10 ÷ 30 Vdc Max ripple: 20% Output current range: 4 ÷ 20 mA Temperature range: - 10° ÷ + 60°C Max thermal drift: < 10% Degree of protection: IP67 Cable conductor cross section: 0,75 mm2 Marking: II 1D Ex iaD 20 T80° C II 1G Ex ia IIC T6 Certified IMQ 08 ATEX 010 Protected against short-circuit and overload Protected against any wrong connection Electromagnetic compatibility (EMC) according to EN60947-5-2 According to: EN60947-5-7/EN60079-0/EN60079-11/EN60079-26 Shock and vibration resistance according to EN60068-2-27/EN60068-2-6 ORDERING REFERENCES INVERSELY PROPORTIONAL Graph 1 DIRECTLY PROPORTIONAL Graph 2 BDC Electronic - Viale Lidice, 37/39 - 10095 Grugliasco (To) - Italy -Tel.
