QUESTION: What size meteorological sensor probes can we mount into the MeteoShield Professional
ANSWER: The MeteoShield® Professional accepts a large variety of probes ranging from small 1 mm Thermistors and 3 mm diameter RTD’s and PT100 sensors from Apogee Instruments and Campbell Scientific, to large 25 mm diameter HMP155 meteorological probes from Vaisala and Rotronic.
The standard cable gland (sensor clamp) which is included with the MeteoShield Pro is an M25 gland which accepts sensor diameters of up to 20 mm (up to 0.787in or just over 3/4” diameter).
A grommet insert adapter is available. It can be purchased at many hardware stores and is usually called a “Cable Gland Reduction Sealing Rubber Insert”.
An M16 gland with a M25 to M16 reduction is available and accepts sensor diameters from 5 mm to 10 mm (up to 0.394in or just over 3/8” diameter).
An M12 gland with a M25 to M12 reduction is also available as shown in the photos and accepts sensor diameters from 3 mm to 6.5 mm (up to 0.256in or just over 1/4” diameter).
