U2352A

Keysight U2352A USB Modular Multifunction DAQ

The Keysight U2352A can acquire up to ±100 mV input signals. Each channel incorporates an instrumentation amplifier and a 4 Hz low-pass filter. The low-pass filter expels undesirable noise from the thermocouple wires to acquire precise estimation data. This model allows the user to choose separate voltage input modes for each channel. The channel will be set to sidestep the enhancer and filter, permitting up to ±10 V input signals to be directly routed to the DAQ gadget analog input. The bandwidth in this mode is greater than 500 kHz. This model also offers a zero mode, during which the positive and negative inputs of the instrumentation amplifier are shorted together. The voltage estimated in this mode compares to the counterbalance voltage of the channel, so the user can subtract this offset voltage from subsequent thermocouple mode estimations to build estimation exactness. This mode is just pertinent in thermo-couple mode.

The U2352A can be utilized with an extensive variety of standard thermo-couple types characterized in the NIST ITS-90 Thermocouple Database. This incorporates types J, K, R, S, T, N, E, and B. This instrument also incorporates an open thermocouple recognition hardware to show the nearness of an open thermocouple.

The U2352A gain and offset alignment factors for each channel are stored in the EEPROM amid factory adjustment and can be recovered preceding taking estimations. This on-board EEPROM additionally stores the module ID, serial number, and date of alignment for the user’s reference. A segment of the EEPROM is additionally allotted for the user to save their alignment information.
