Sensor Measurements
CompactDAQ systems are more rugged than multifunction I/O devices and can measure sensors like IEPE accelerometers, thermocouples, and load cells. Select from more than 70 measurement modules and eight chassis (USB or Ethernet) available to assemble your optimal measurement system.
Recommended Uses:
- Mechanical tests
- Logging sensor data to a PC
- Shock and vibration tests
- Acoustic measurements
More Speed and More Channels
PXI systems are like a PC, except they have up to 17 expansion slots so you can keep adding high-speed, synchronized channels for large measurement systems.
Recommended Uses:
- Research and electronic test benches
- PCBA manufacturing test systems
- I/O for firmware test
- Sensors that output 10 V
Waterproof, Shockproof DAQ
IP67-rated, ultra-rugged design for voltage, strain/bridge, accelerometer/microphone, and thermocouple measurements. Link and sync with a single Ethernet cable.
Recommended Uses:
- Engine test cells
- Static fire rocket tests
- Structural research
- Heavy equipment field test
