Signal Conditioning is an important aspect of any test system. The conditioner converts the signal from a transducer into a voltage that represents the physical attribute the transducer is designed to quantify. The Oneiric Systems, Inc. Signal Conditioning System takes the approach that each channel should be configured independently. The backplane is designed to interface directly with National Instruments 68 pin MIO devices and provides expansion for all of the signals available at the connector, but can be used as a conditioner without connection to and DAQ device if desired. With the single channel conditioning approach, a transducer type can easily be changed without changing the channel being digitized. For example, if a system is designed with a string pot to measure displacement, and it is later found that an LVDT is required for the application. The user would only need to replace the conditioning card, wire the LVDT to the proper terminals, and re-calibrate the system with the new transducer. Re-configuring the software to acquire data from another channel is not necessary. This approach is also helpful when designing a system because the designer can concentrate on the overall design of the system and focus on the individual channels when ready to do so.
Conditioner cards available include:
-Strain Gage Bridge
-ICP accelerometer and microphone
-LVDT
-Thermocouple
-Potentiometer
-4-20 mA with or without 24 VDC excitation
-Voltage input (with or without excitation)
