The LDX-4 is a dc powered signal conditioning amplifier and power supply for ac LVDT's. Its compact, rugged case can withstand industrial installations and protect laboratory grade electronics. Complete zero and span adjustments allow the LDX-4 to be used with any LVDT with an output between 45 and 450 mV/V full scale. Selectable outputs of ±5 V or ±10 V interface with recorders, displays, and other instruments. Also, when using the ±5 V output range, a second 0 - 20 mA signal is available for retransmitting the signal over long distances.
SPECIFICATIONS Supply Voltage: 10 to 30 Vdc Supply Current (voltage output): 140 mA max. with 10 Vdc supply voltage; 60 mA max. with 30 Vdc supply voltage Supply Current (current output): 180 mA max. with 10 Vdc supply voltage; 70 mA max. with 30 Vdc supply voltage Noise on Power Supply (typical): 20 mV pp @ 100 kHz Input Protection: Over voltage, reverse connection Transducer Energization: 3V rms @ 5 kHz Transducer Range:45 to 450 mV/V full scale Output Voltage (selectable): ±5 Vdc or ±10 Vdc full scale Load Resistance: 1 kΩ minimum Analog Output Current: + 20 mA full scale into 1500 Ω maximum (only with 5 V range selected) Offset Range: 0 to 100% Gain Temperature Coefficient: < 200 ppm/°C Output Temperature Coefficient: < 200 ppm/°C Output Noise: < 20 mV pp @ 10 to 100 kHz Non-Linearity: < 0.1% BSL Temperature Range: 0 to 60°C (-18 to 140°F) Weight (approx.): 300g (11 oz) Dimensions: 40 H x 65 W x 120 mm L (157 x 256 x 4.72")
