before applying power to the sensor.
If you extend the Type K output wires, ensure Type K thermocouple cable and connectors are used.
Using copper or other metals will affect the accuracy of the measurement.
OPERATION
Once the sensor is in position and the appropriate power, air and cable connections are
secure, the system is ready for continuous operation by completing the following simple
steps:
•
Turn on the power supply
•
Turn on the measurement instrument
•
Read / monitor the temperature
CONFIGURATION AND READING TEMPERATURES
The sensor is fully configurable via a smartphone or tablet with NFC capability. Download the
free app for Android devices from the Google Play Store, or for iOS devices from the Apple
App Store (search "PyroNFC")
Touch the NFC device against the back of the sensor to read the measured temperature. On
Android, the reading updates continuously while the phone is touching the sensor. On iOS,
the temperature is updated once each time the user taps "update" in the app.
The sensor must be powered to read the measured temperature with the app.
To change settings, edit the configuration parameters in the app, then tap "Write to Sensor".
Touch the NFC device against the back of the sensor to write the settings. A message will
appear in the app to confirm the settings have been written successfully.
Allow at least 5 seconds for the new settings to take effect. There is no need to power the
sensor to read or write the settings.
CONFIGURATION (MODEL PN151K):
The Type K thermocouple output has a temperature range of 0 to 1000°C. This is not
rescalable.
The settings in the app for configuring the voltage output type and scale on models with
linear voltage output have no effect on PyroNFC-K models with Type K thermocouple output.
Select the correct sensor model from the drop-down list in the app to hide these options.
