Pressure Sensor 400, order code PS400-BTA, $189
Specifications and User Guide
-Primary Test: Connect the sensor to a Vernier interface and run the data-collection program. The units for the default readings are kPa and they should be reasonable for the altitude at which the sensor is being used (around 101 kPa at sea-level). If you plug the output with your finger, the pressure should rise slightly (~5 kPa).
-Minimum software version: Logger Pro 3.10.1, LabQuest App 2.6
Range: 0 to 400 kPa
Maximum pressure can withstand: 800 kPa
Sensing element: Honeywell PX2 Series
Accuracy using factory calibration: +/- 2 kPa
Accuracy using custom calibration: +/- 1 kPa (1 point calibration at atmosphere)
Temperature range: -40 degC to 125 degC
Inlet/port type: 1/8-27 NPT
-Tightening wrenches and plumber's tape to ensure a tight seal
-Double-barb brass connector to fit flexible tubing
-Nickel-plated brass push-to-connect connector to fit more rigid tubing
-Two-foot section of nylon tubing
-Two-foot section of plastic tubing
The Pressure Sensor is calibrated to atmospheric pressure in Portland, Oregon before shipping. You may wish to recalibrate with the atmosphere of your region by doing a one-point calibration.
1. Connect the Pressure Sensor 400 to an interface and launch the software.
2. Initiate the calibration procedure and make sure the one-point calibration option is checked. This should be the default option.
3. Enter the known calibration value in the Reading 1 box.
4. Once the readings in the input field stop changing significantly, click Keep to record the input value. After Keep is selected, a new calibration is created. The calibration is added to the list of available calibrations and it is marked as Not Saved. This new calibration becomes the current calibration for the sensor.
5. If you want to use the calibration for the current session only, click Done to complete the calibration process. To save the calibration onto the sensor, click the storage tab and save it to the sensor.
