Pressure Transducers

Description

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.
