Field of View Diagram

The diagram shows the measured spot size for 90% of the detected energy. Sensors can measure longer distances than the diagram shows, and the accuracy is not affected by the measurement distance in clean air. This is because the PyroNFC detects only the wavelengths of infrared radiation that are not absorbed by the atmosphere.

Electromagnetic Compatibility Standards

EN61326-1, EN61326-2-3 (Electrical Equipment for Measurement, Control and Laboratory Use – EMC Requirements)

Installation (all dimensions in mm)

Mounting Bracket

Fixed and adjustable mounting brackets

Provides 1 or 2 axis adjustment for aiming the sensor. Model shown: FBN (fixed mounting bracket, 1 axis adjustment).

Model: FBN (fixed); ABN (adjustable)

Air purge collar

Air purge collar

The lens of all infrared temperature sensors must be kept clean for accurate measurements. This accessory helps stop dust and condensation from settling on the lens. Includes barbed air fitting and long mounting screws.

Model: APN

Calibration Certificate

UKAS traceable calibration certificate at 3 standard temperature points.

Model: CALCERTA

Extended Cable

Calex can optionally fit a longer cable to the sensor (30 m max). The cable can also be extended by the user. See Ordering.
