Wireless Pressure Sensor - PS-3203

PS3203_MAIN.jpg

Overview

Make accurate and consistent measurements of gas pressure, regardless of ambient conditions, and explore how chemical reactions affect gas pressure. In combination with a temperature probe, study the Empirical Gas Laws.  Can also be used in applications that previously required our Low Pressure/Barometer sensor.

The Teaching Advantage

Measures pressure relative to an internal sealed reference vacuum, which allows the collection of reliable data even when the pressure within a system drops below ambient pressure.

Supports common units (kPa, atm, psi, mmHg, or N/m2) for many applications

Typical Applications

  • Measure transpiration rates 
  • Measure osmosis and pressure changes inside a model cell
  • Measure rates of enzyme catalyzed reactions
  • Conduct weather experiments
  • Measure changes in elevation
  • Measure chemical reaction rates
  • Measure respiration rates
  • Conduct air foil studies
  • Model a human lung.
  • Study Vapor Pressure vs Temperature
  • Add a temp sensor to investigate Gas Laws (Ideal, Charles', Boyle's)

Special Features

  • Bluetooth® and USB connectivity with a long-lasting rechargeable battery
  • Logs pressure data directly onto the sensor for long-term experiments for activities that couldn't be performed using sensors previously.
  • No interface required! Connects directly to your devices via Bluetooth® Smart.
  • Includes a syringe, tubing and the connectors and locks you need for an array of pressure experiments.

Bluetooth 4 Connectivity

Required Software:

PASCO products that use Bluetooth® 4 technology - wireless sensors, smart carts, and the AirLink Interface - require the latest versions of our software. PASCO Capstone 1.9.0 is available for Mac and Windows. SPARKvue 2.7.0 is available for Mac, Windows, iOS, Android and Chromebooks.

Compatibility/System requirements

Any current model Mac, iPad, iPhone, Android tablet or Android phone will support direct connection to PASCO Bluetooth 4 devices.

Windows computers/tablets, Chromebooks and older Macs currently require the PS-3500 USB Bluetooth 4.0 Adapter to connect to PASCO’s Bluetooth 4 devices.

Full compatibility details are available, including compatibility information for older computing devices.

Datalogging

Independent datalogging 

Long term data collection directly on the sensor

In logging mode wireless sensors collect data to their onboard memory for hours, days, weeks or even months at a time without needing to be connected to a computer, tablet, Chromebook or smartphone.

When the experiment is concluded, simply connect the sensor to a device running PASCO software and download all the measurements it recorded.
