Inductive displacement transducer IWE260 - 1

Inductive Linear Displacement Transducers Model IWE 260 Measuring strokes : 80 mm, 170 mm, 240 mm, 360 mm ■ Contactless, robust sensor system ■ Infinite resolution, no hysteresis ■ Digital interface SSI ■ Resolution 12 Bits / natural binary ■ Gauge with spring return up to 100 mm ■ Protection class IP 66 Construction and operating principle The displacement transducer operates according to the principle of the differential choke, i.e. an inductive half bridge. It consists of two coils which are encapsulated in a stainless steel cylinder. A mu-metal plunger core causes opposing changes of inductance when it is displaced through the centre of the coils. These changes are converted by the integral electronic circuit into a signal proportional to the displacement. A 12 bits A/D converter supplied a proportional digital signal wich can be calibrated before delivery via on integral-controler. The transducers are completely sealed to ensure positive protection against vibration, shock, humidity, oil and corrosive matter. Standard measuring strokes: 80 mm, 170 mm, 240 mm, 360 mm Special calibration Up on request the measuring stroke can be reduced without affecting neither the resolution nor the case length, e.g. 200 mm measuring stroke (IWE 260/200) will be generated using IWE 260/40.

Note: If not otherwise indicated all data are valid at 20° C ambiant temperature, at Vs = 24 VDC and 30 min. turn-on time. Measuring direction The measuring signal increases when the plunger moves in direction of the connector. Up to request the reverse action can be calibrated before delivery.

Inductive displacement transducer IWE260 - 2

Inductive Linear Displacement Transducers IWE 260 SSI (Synchron Serielles Interface) The absolute information derived by the transducer is converted into serial information and the transmitted to a receiving electronic circuit in synchronism with aclock. Important advantages are: Low number of data lines and high reliability. Electrical connections at plug (View at connecting face of counter plug) L1 = Plunger in central position: 2047 positions. The applicable A-No. is allocated after the definition of the deviation when ordering. No A-No. is given for standard versions as specified in the...
