Product Description

The Universal Serial Bus (USB) interface is a popular digital interface for quick and easy connection of measurement devices to desktop & laptop computers and other digital measurement instrumentation.

A USB connection provides a global standard for the physical electrical connection, communication and powering of digital sensors and measurement instruments. A single cable is used for sending all the read & write commands, and providing a low dc supply voltage.

USB is a popular method for connecting measurement devices together in a research laboratory environment on experimental test rigs, where all test equipment is close by on the same test bench or rig.

The majority of USB measurement devices come with application software which can be installed on a laptop or desktop computer. USB provides the user with a plug & play set-up that can be up and running very quickly without the need for wiring, separate power supplies or signal conditioning instrumentation.

Pressure sensors are measurement devices for detecting variations in pressure of liquids or gases. Typically a pressure sensor is made of two subcomponents, an electromechanical assembly on the frontend, and a signal conditioning module on the backend.

The frontend of the pressure sensor is connected directly via a thread or clamped seal to a pipe or vessel containing the liquid or gas to be measured. The pressure generated by the liquid or gas will apply a force to a sensitive exposed surface area within the electromechanical assembly which produces a physical change to the material, such as a deformation. This physical change is translated into an electrical change by smaller elements incorporated into the sensitive part of the assembly, typically on the reverse side of the surface in contact with the liquid or gas.

Since there are many different types of electromechanical technology used to measure pressure, producing very different electrical characteristics, it is necessary to add on a signal conditioning module to rationalise the electrical signal and convert it to one which is a commonly used standard within a particular industry or application.
