INDUCTIVE PROXIMITY SENSORS FOR COLD ROLLING MILL (METAL IND
Inquiry (采购产品): INDUCTIVE PROXIMITY SENSORS FOR COLD ROLLING MILL (METAL INDUSTRY)APPLICATION WHICH MUST BE ANTI COOLANT Following are chemical properties of liquid called 'coolant' which is used in cold rolling mill applications Complete specifications for Inductive proximity selection in cold rolling mill application Parameter Unit of Measurement Specification Technical Specifications are : Acidity mgKOH/gm 18.2 to 22.2 Model No & make ? ( Searching for it ) Sap Number mgKOH/gm 210-232 Type of Sensor : Inductive Viscosity @400C mm2/s 46.5 -52.5 Electrical design 2-wire DC PNP/NPN Output normally open Appearance-Clarity Clear Clear Dia of sensor Metal thread M30x1,5 pH -- 5.0 to 5.6 Mounting Flush type (fully threaded) Conductivity μS/cm Max500 Operating voltage (10 ... 36 VDC (24 v dc) Oil concentration % 2.0 to 4.0 Wire 2 wire Chloride in Emulsion ppm Max50 Probe length 2 mtr maximum Iron in emulsion ppm Max250ppm Sensing range 10 mm minimum & 15 mm Max. Sap Value mgKOH/gm Min 190 Switching status LED yellow or red Acid Value mgKOH/gm 15-25 Protection IP 68 Tramp oil % Max15 Short-circuit protection required Colour Dark Amber Reverse polarity protection required Physical State Liquid Overload protection required ESI 0.60 to 0.75 Remarks: What we are looking for : 1 Basically we are looking for an inductive proximity sensors which should not have reactiveness nature with this emulsion called 'coolant'. (Pl see tech specs) 2 All the proximities will be wet permanently in the coolant & temprature will be 55 deg C in mill application. 3 The life of sensors should be high & bearable of aggressiveness of chemical properties of coolant. 4 Pleae suggest Specific Model no , make with all the specifications & technical brouchure. **** Hidden Message ***** vivek bhatnagar 401506 Company: JSW STEEL LTD E-mail: vivek.bhatnagar@jsw.in **** Hidden Message ***** vivek.bhatnagar@jsw.in
