The mechanical sensing of linear motion is provided by a front guided or loose push rod. LVDT linear sensor versions are available with a spring-suspended probe tip (MDCT) with internal spring return, with ball joints (MDCG) to compensate for vertical or horizontal misalignment and with a loose push rod (MDCL). The inductive measuring principle of the MDC is configured with a cast coil in LVDT winding. The electronics, which convert the position into a linear analogue signal, are integrated into the sensor housing. The non-contact measurement principle provides a long service life and allows high dynamic applications, especially where small oscillating movements need to be detected. Inductive measurement provides absolute values, true power-on and high resolution. The rugged design of the inductive MDC with IP65 (optional IP67/68) sealing allows it to be used in harsh environments.
