Detailed Description

The 41303-5A houses one 107, 108, 109, CS215, or HMP60 probe. The probe fits in the bottom of the shield and is held into place with screws.

The 41303-5A includes a 2-in. u-bolt with a plastic v-block. The u-bolt is placed in the holes on the side of the bracket for attachment to a mast or vertical pole. The u-bolt is placed in the holes on the bottom of the bracket for attachment to a crossarm.

The 41303-5A replaced the 41301 in 2005. The biggest improvement of the 41301 is that it can be mounted to either a vertical pole or horizontal pipe. The retired 41301 only mounted to a vertical pole.

Frequently Asked Questions

Number of FAQs related to 41303-5A: 2

  1. To measure ambient temperature and relative humidity (RH), mount the HC2S3-L probe inside a 41003-5 or 41003-5A 10-Plate Radiation Shield. The 27731 hex plug is shipped with the HC2S3-L so that it can be used with older 10-plate radiation shield models. The 6-plate radiation shield (pn 41303-5A) cannot be used with the HC2S3-L.
