Extensive application possibilities

The model CPT2500 USB pressure sensor can be connected to any PC with a USB interface, via the model CPA2500 USB adapter.

For the USB adapter, there are stainless steel pressure sensors with measuring ranges up to 1,000 bar (14,500 psi) available. The USB adapter automatically recognises the measuring range of the connected pressure sensor and guarantees a high-accuracy pressure measurement.

Functionality

The measuring interval for pressure recording can be set in the range from 1 ms ... 10 s. With a recording interval of more than 5 ms the following data is recorded in addition to the current measured value:

  • the mean value over the recording interval
  • the maximum and minimum values during the recording interval

Thus pressure spikes within the overall recording interval can be very easily identified. It is also possible to set start and stop conditions for the recording. In this way it is possible to detect pressure spikes with a resolution of up to 1 ms. The CPT2500 is thus very well suited to all applications where, over a limited time span, pressure profiles must be recorded and analysed with high resolution.

Software

The USBsoft2500 and USB-ScanSoft software are delivered as standard with the USB adapter. With it, all settings for recording the pressure profiles can be made. The recorded measured values can be graphically displayed and evaluated.

Apart from the USBsoft2500 and USB-ScanSoft software, the WIKA-Cal calibration software is available for calibration tasks. Using this software, the data is automatically transferred into a printable calibration certificate. WIKA-Cal also offers, over and above PC-supported calibration, the management of the calibration and instrument data in an SQL database. A USB interface is available for the data transfer.

Complete service case

For easy transport and safe storage, the USB adapter is delivered in a compact transport case, which can also hold one or more pressure sensors.

Certified accuracy

For each reference pressure sensor, the accuracy for the complete measuring chain is certified by a factory calibration certificate which accompanies the instrument. On request, a DKD/DAkkS calibration certificate will be provided for this instrument.
