Sensors for National Instruments DAQ


The IA-400N is a signal conditioner and amplifier for NISensors transducers. It provides four channels of excitation power, gain, and noise filtration. It exhibits low system noise and offset, making it suitable for use with high resolution data acquisition systems. Each channel of the IA-400N has a switch to allow selection of either a 40 Hz or 10 kHz low pass filter.  This makes the IA-400N an ideal solution for conditioning signals from low-bandwidth transducers such as those used to measure blood pressure or force as well as those applications requiring wider bandwidth.

When used with the C-ISO-256N , the IA-400N can be used to measure Biopotentials such as ECG, EMG etc.  from humans.

Gain control on the IA-400N is very straightforward. A programming resistor in the DIN-8 connector is used to set the gain. NiSensors transducers set the IA-400N gain to the optimal value for a given measurement. However, this does not limit the IA-400N to use with NiSensors transducers. Many transducers, can be modified to work with the IA-400N.

The IA-400N is an inherently low offset device. The IA-400N user experience is simplified as a result.

The IA-400N is packaged in a low profile enclosure that provides both durability and noise immunity. The device has a small foot print measuring just 6.2 in. x 5.3 in. x 2.3 in. (17.5 cm x 13.5 cm x 6cm)and multiple units are easily stacked to save bench space.
