DEMOD-DC Low Cost LORD LVDT Signal Conditioner
The DEMOD-DC in-line signal conditioner makes LVDT sensors as easy to use as a potentiometer. With integral signal conditioning electronics, simply connect power, ground, and analog out, and the DEMOD-DC outputs a buffered, high-frequency response voltage proportional to linear position. During the manufacturing process the analog output voltage is digitally trimmed, ensuring every LVDT’s offset and gain values produce optimal system output accuracy. The DEMOD-DC provides internal power regulation and reverse polarity protection and operates with a wide range of input voltages.

Rugged, environmentally insensitive sensors are ideally suited for integration into a multitude of in-line production process verification tasks.
Miniature size allows access to nearly any feature.
Many “standard” features can be customized to fit a specific application:
- custom calibrated stroke ranges
- modified body or core lengths
- hermetic or “pressure-equalized” versions
Miniature sensors allow for integration into complex mechanical assemblies for displacement feedback of mechanical grippers, relative position of targets and closed loop position control.
Adjustable filtering allows for high bandwidth which enables quick feedback and responsive machine control systems.
Multiple sizes, stroke lengths, accuracy, and filter settings provide sensors for every test and measurement application.
Calibrated displacement systems shortens startup time and ensures accurate results out of the box.
Integration with our wireless sensors (V-Link-200 for example) enables rapid integration and the added features of SensorConnect and/or SensorCloud.
