Supported Applications
The Omega LDX-4 is a DC-powered signal conditioning amplifier and power supply designed for AC Linear Variable Differential Transformers (LVDTs). It provides transducer excitation and selectable analog outputs, specifically configured to work with the LD320 series of LVDT transducers. The unit features adjustable gain and zero controls.
Operational warnings indicate that this equipment is not intended for use in explosive atmospheres or safety-critical environments. Additionally, these products are not designed for human applications.
Operating Conditions & Performance
The LDX-4 operates from a single DC supply voltage of 10 to 30 Vdc. It energizes the connected transducer with an excitation signal of 3 Vrms @ 5 kHz and accepts input ranges from 45 to 450 mV/V full scale.
Performance specifications include:
- Non-Linearity: <0.1% BSL
- Gain Temperature Coefficient: <200 ppm/°C
- Output Temperature Coefficient: <200 ppm/°C output
- Noise: <20 mV p-p @ 10 to 100 kHz (typical noise on power supply is 20 mV p-p @ 100 kHz)
The unit operates within an ambient temperature range of 0 to 60°C (-18 to 140°F). Physical dimensions are 40 W x 65 H x 120 mm L (1.57 x 2.56 x 4.72"), with an approximate weight of 300 g (11 oz).
Configuration Options
The series offers configurable analog output signals and power consumption profiles based on the selected mode:
- Selectable Output Voltage: ±5 Vdc or ±10 Vdc full scale.
- Analog Output Current: 20 mA full scale into a maximum of 1500 Ω (available only when the 5 V range is selected).
- Load Resistance: Minimum 1 kΩ for voltage outputs.
The unit incorporates internal voltage regulation and input protection against overvoltage and reverse connection. Electrical connections are made via a connector, with specific pin assignments detailed in the installation documentation under "Electrical Connections" (Section 4.3). The housing is described as a rugged compact case; related family manuals reference die-cast aluminum construction for mechanical protection.
Power consumption varies by output type and supply voltage:
- Voltage Output Mode: Maximum 140 mA at 10 Vdc supply; maximum 60 mA at 30 Vdc supply.
- Current Output Mode: Maximum 180 mA at 10 Vdc supply; maximum 70 mA at 30 Vdc supply.
Key Product Differences
The LDX-4 is offered as a single model number (LDX-4) within this series. The device supports both voltage and current output configurations, with the 20 mA analog output restricted to operation when the ±5 Vdc range is selected.
