Specifications

Ordering Information

Temperature Probe (wiring configuration option

required)

43347 - R.M. Young RTD NIST calibrated Temperature Probe

in 4-wire configuration with 3 m standard cable. Other cable

lengths available in 5 m increments e.g. 5, 10, 15 m.

Calibration Option

Optional 3-point calibration for the 43347 that provides

±0.1°C uncertainty (-50° to +50°C).

Aspirated Shield

43502 - R.M. Young Aspirated Radiation Shield with AC

power supply (1.8 m lead).

Accessories

41003-5 - 10-plate Gill Naturally Aspirated Radiation

Shield for applications that do not require fan-aspiration. It

requires the #27251 split nut (see below).

#27251 - Split nut plug that is required to mount the 43347

in the 41003-5 radiation shield.

009043 - RAD14 - 14 plate unaspirated radiation shield

(14-25 mm dia).

CM210 - Crossarm-to-Pole Bracket for attaching the 43502

onto two tower legs via a crossarm (one of the CM210s is

included with the crossarm).

006903 - Suitable power cable for 43502 - specify required

length in metres to reach AC power supply.

4WPB1K - 4 wire PRT module (1k) required if not using the

current excitation outputs of a CR3000 or CR5000.

43502 Aspirated Radiation Shield

Aspiration Rate: 5 to 11 m s-1 (16 to 36 fps) depending

on sensor size

Ambient Temperature: < 0.2°C (0.4°F) RMS at

1000 W/m2 intensity

Delta T: < 0.05°C (0.1°F) RMS with like shields equally

exposed

Power Required: 12 to 14 Vdc at 500 mA for blower

Mounting: V-block and U-bolt for vertical pipe with 2.5 cm

to 5.0 cm (1.0 in. to 2.0 in.) diameter

Length: 33 cm (13 in)

Diameter: 20 cm (8 in)

Weight: 1.1 kg (2.5 lb)

For the 2 m measurement, the 43502 attaches to the legs

of a UT20 or UT30 tower via a CM202, CM203, CM204, or

CM206 crossarm. Two CM210s can be used to attach the

crossarm to two tower legs.

For the upper measurement, attach the 43502 to the

top most mast of a UT930 tower (10 m measurement

height).
