Low Range Digital Pressure Sensor | USB | Pa600-USB-LR

Low range pressure measurement direct to your PC via USB


Applied Measurements digital low range pressure sensor Pa600-USB-LR enables pressure measurements to be sent directly to your PC or laptop via the USB interface.  Simply install the sensor, connect the cable, plug the USB interface DSCUSB into the USB port of your computer or laptop and download the free software to get started.

The software is user-friendly and free to download and allows real-time monitoring and simultaneous recording of the pressure data to a CSV file for analysis, of up to 100Hz.  The USB interface (DSCUSB) needs no external power cable as it takes all the power it needs directly from the USB port of your PC or laptop.

The pressure sensor itself has a high accuracy of <±0.15% full scale and is extremely compact.  It features a high-performance ceramic sensing element and once connected to the USB interface delivers precise pressure measurements with its 24-bit digitisation circuit to a resolution of up to 1 part in 20,000 depending on the chosen data acquisition rate.

Additionally, the Toolkit software allows you to change configuration settings including:

  • Measurement Units: The standard scaling units (bar) can be changed to psi, kPa, millibar and many others with just a few clicks.
  • Sampling Rate: 1Hz to 100Hz is possible, with lower rates offering higher resolution
  • Digital Filtering: Allows you to smooth out any unwanted pressure fluctuation from your measurements.

If you have multiple digital pressor sensors in use, you can use our DSCLOG24 software which allows up to 24 channels of measurement.

Each digital low range pressure sensor Pa600-USB-LR is supplied in a compact carrying case with its USB interface module and connecting cables along with a UKAS traceable calibration certificate.
