UmagtrolDI Series Displacement Transducers FEATURES • Large measuring range: Piston displacements from 50 to 1000 mm; 80 to 250 mm for DI 63X models • Current-based output signal (4 to 20 mA) for displacement • Built-in temperature measurement • Very long life: No moving parts and therefore no wear of components (Eddy-current principle) • Slim measuring system allowing large measuring range • Insensitive to metallic impurities in the working fluid • High shock and vibration resistance • Capable of withstanding pressures up to 450 bar • Robust construction, designed for permanent operation in hydraulic systems • Standard temperature version, up to 80 °C (DI 5XX) • High temperature versions, up to 125 °C (DI 60X and DI 61X) or up to 200 °C (DI 63X) • EMC susceptibility conforms to European standards DESCRIPTION Magtrol’s line of Displacement Transducers provide contactless measurement of absolute piston position in hydraulic and pneumatic cylinders and other applications. Their robust construction, large insensitivity to shocks and very long life (due to no moving parts and therefore no wear of components) make them both cost effective and very reliable. Magtrol transducers offer a wide range of operational temperatures and admissible pressure resistance for even the most demanding applications. The transducer provides a direct 4-20 mA output signal corresponding to the measuring range, as well as VDC temperature output. As an option Magtrol offers the CST 113 Signal Converter, which allows the complete chain to be calibrated according to the specific needs, either in current or voltage output. BASIC CONFIGURATION- APPLICATIONS The DI series of displacement transducers were developed principally for OEM applications in the hydraulic industry. They enable the direct and reliable measurement of the position of: • Hydraulic Cylinders • Steam Inlet Valves • Control Valves • Propellers • Servo Controls • Stone Crushers Their design is such that the installation cost is kept to a minimum. This cost-effectiveness results from the limitation to one fixed standard signal of 4 to 20 mA with very precise determination of the measurement interval (from 0 to full scale) on the sensing element. — Power Supply: 20 to 32 VDC / min 70 mA ► Displacement: 4 to 20 mA 20 to 4 mA (DI 63X transducers only) ► Temperature: 7.5 VDC ±80 mV at 20 °C + 30 mV/°C (DI 5XX)

Operating Principles Eddy-Current Principle Characteristics of the Output Signal Magtrol Displacement Transducers use the principle of Eddycurrent measurement. An aluminum tube moves along the transducer’s coil changing the induced Eddy-current losses, thus changing the coil impedance. An electronic circuitry housed in the transducer head, transforms the information of the measuring tube position into a linear signal. This circuitry uses modern SMD (surface-mounted device) technology, giving it robustness and reliability. The sensor is actively compensated for temperature changes. DI Series...
