SMPL DCDT Signal Conditioner

DCDTs, or Direct Current Displacement Transducers, are one of the most commonly used, high precision displacement measurement transducers. Interfacing to them can be tricky though. They need a unipolar DC input (often 6-24 VDC) and the output is a bipolar (plus and minus) signal of a different amplitude than the DC input voltage. The DCDT Signal Conditioner makes working with these transducers painless and easy.

The signal conditioner generates an adjustable excitation voltage to power the DCDT, and will take the bipolar input voltage back from it. Changing the excitation voltage can help tune the output range of the transducer to match your system and allows the use of almost any DCDT on the market.

There is also an instrumentation amplifier on the signal conditioner, providing a high input impedance for the DCDT, which ensures proper operation of the instrument and the closest adherence to the factory calibration of the instrument. This device is equipped with an adjustable gain. This provides a way to perfectly tune the output of the DCDT to match the input range of your DAQ system if you find your signal is too small to do so.

Output from the signal conditioner can also be offset. This lets you set a zero position for the transducer or offset the signal to use more of the range of the connected DAQ hardware.

Finally, the signal conditioner offers a way to apply an input filter to clean up your signal. The unpopulated components allow you to build a differential and common mode low pass filter in which you decide and set the cutoff frequency. This is great for removing noise from the power supply, adding an anti-alias filter, or just cleaning up a slow signal. Use our free filter calculator to determine the component values you should use.
