The temperature of both the bridge structure and its environment changes on a daily and seasonal basis and influences both the overall movement of the bridge deck and the stresses within it. The former has implications for the design of the bridge bearings and expansion joints, and the latter on the amount and disposition of the structural materials.
Relative Humidity & Temperature Probes
The Model 41382 Relative Humidity/Temperature Probe combines a high accuracy, capacitance type humidity sensor and precision Platinum RTD temperature sensor in one probe. This probe offers a choice of 0-1 VDC or 4-20 mA outputs for T and RH.
Model 41342 Temperature Probe offers accurate temperature-only measurement. Three output options are available: 0-1 VDC, 4-20 mA, and 4 wire RTD. Probes are easily installed in YOUNG naturally ventilated (multi-plate) and aspirated radiation shields. A junction box is provided for cable terminations.

Probes Protection
The Aspirated Radiation Shield Model 43502 provides maximum sensor protection from incoming short wave and outgoing long wave radiation.
The shield employs a triple walled intake tube and multiple canopy shades to effectively isolate the sensor from precipitation and solar radiation. A continuous duty DC blower provides constant flow of ambient air over the sensor. A variety of temperature and relative humidity probes are available.

The Multi-Plate Radiation Shield Model 41003 protects temperature and relative humidity sensors from error-producing solar radiation and precipitation. Compact size and light weight make this shield useful for many applications.
The multiple plates have a unique profile that blocks direct and reflected solar radiation, yet permits easy passage of air. The plate material is specially formulated for high reflectivity, low thermal conductivity, and maximum weather resistance. The rugged U-bolt mounting clamp attaches easily to any vertical pipe up to 2 inches diameter. Model 41003 employs a universal clamp-type adapter to securely hold sensors up to 16 mm diameter. Model 41003P has a custom sized adapter to fit a sensor from 16 mm to 26 mm diameter (24 mm is supplied unless otherwise specified). A variety of temperature and humidity probes are available.
