UPS-GP General Purpose Pressure Sensor, Pressure Transmitter with USB Interface

The UPS-GP is based on our popular TPTd i2c pressure transmitter which we have integrated directly with a USB interface to provide a direct and simple interconnection to the USB port of your PC, Raspberry Pi, Arduino or any device with a USB input. The supplied PC Graphical User Interface allows a clear display of pressure with a real time graph, logging capability and a simple to use command set to communicate to the UPS-GP for bespoke applications.

The onboard 16-bit microprocessor enables a high level of linearisation, temperature compensation and calibration to be performed on the sensor in the factory ensuring great accuracy, stability and repeatability are met.

What is a USB Pressure Sensor?

A USB pressure sensor is a device that measures pressure and converts it into an electrical signal that can be read by a computer through a USB connection. Key features of a USB pressure sensor include:

  • Pressure sensing element – This is the part of the sensor that detects changes in pressure, usually based on silicon-on-sapphire technology like piezoresistive or capacitive sensing. Common pressure ranges are from 0-1 bar up to 0-500 bar.
  • Analog to digital converter (ADC) – This converts the analog signal from the sensing element into a digital value that can be read over USB. Higher resolution ADCs provide more precision.
  • USB interface – This allows easy connection to PCs and other devices with a USB port. No external power is required as power is provided over USB.
  • Housing – The sensing element and electronics are enclosed in a protective casing with an opening/port to expose the sensor to the pressure.
  • Software – Drivers and libraries are provided to allow easy integration into programming languages and software applications.

USB pressure sensors can measure air, gas or liquid pressure and have applications in weather monitoring, manufacturing, automation, lab research, and more. Compared to analog sensors, the USB interface makes it easy to log and analyse pressure data on a computer. Overall, USB pressure sensors provide a convenient way to add pressure measurement to a project or system.
