Pressure Transducers


The Pressure sensor measures-14.5 up to 10000 PSI when connected to a Dataq Instruments Data Acquisition product or Data Logger.

The pressure sensor allows Dataq Instruments data acquisition and data logger units to acquire oil, fuel, air, brake fluid (DOT3/DOT4) or water pressure (PSI) information. The combination of these two products provides a compact solution, with transducer excitation provided by the data logger. The logger itself allows data to be communicated to a connected PC over either a USB or Ethernet interface.

Customized Ranges

All ranges start at 0 psi, meaning we can't customize one for the range of 30-400psi

For range between 0 to 99 psi, any integer numbers*

For ranges between 100-999 psi, any integer in the format of XX0, for example, 130 psi.

For ranges between 1000-9999 psi, any integer in the format of XX00, for example, 1300 psi.

* Ranges lower than +5 PSI has 0.5-1% accuracy
