Overview

The Q7.1 measured the difference between incoming and outgoing radiation. A thermopile output a voltage proportional to the temperature difference between the top and bottom surfaces of the radiometer.

Technical Description

The Q7.1 measured the difference between incoming and outgoing radiation. A thermopile output a voltage proportional to the temperature difference between the top and bottom surfaces of the radiometer.

As shading and reflection represent sources of error to the net radiation measurement, the Q7.1 was typically deployed at some distance to the primary instrument mount. A simple vertical pipe affixed with a CM210 mount was recommended for this purpose.

Nominal calibration factors: 9.6 W m-2 mV-1 for positive values; 11.9 W m-2 mV-1 for negative values.

Specifications

  • 9.6 W m-2 mV-1 for positive values
  • 11. 9 W m-2 mV-1 for negative values
  • Time constant: Approximately 30 seconds
  • Size of sensing head: 57 x 72 x 177 mm
  • Support arm diameter: 20 mm
  • Support arm length: 750 mm

  1. The information included on a calibration sheet differs with each sensor. For some sensors, the sheet contains coefficients necessary to program a datalogger. For other sensors, the calibration sheet is a pass/fail report.

  2. This depends on the information contained in the calibration sheet:

    • If the calibration sheet contains coefficient information, Campbell Scientific keeps a copy, and a replacement copy can be requested.
    • If the calibration sheet does not contain coefficients, Campbell Scientific does not keep a copy. It may be possible to contact the original manufacturer for a replacement copy.
