External Amplifier IMA2 LVDT

Measuring amplifier for inductive displacement sensors (LVDT)

The IMA2 LVDT measuring amplifier is designed to convert the output signals of inductive sensors into standardized output signals. The amplifier is factory-configured according to the selected version and provides the connected LVDT with an excitation of 1,2 Vrms or 5 Vrms at a frequency of with 2.5 or 5 kHz (max 20 kHz). The most important standardized analogue signals are optionally available at the output (0 ...5 V, 0 ...10 V, ±5 V, ±10 V, 0 ...20 mA, 4 ...20 mA).

The device is powered by a galvanically isolated 24 V DC supply and features integrated overvoltage protection of up to 40 V for safe operation. With a relative linearity deviation of less than 0.01% F.S. and a residual ripple of under 20 mV, the amplifier guarantees high measurement accuracy. All electronics are housed in a compact Phoenix UEGM enclosure designed for DIN rail mounting. Thanks to its low weight (100 g) and a wide operating temperature range of -25 °C to +85 °C, the IMA2-LVDT is suitable for a broad spectrum of industrial applications.
