Model TTH-1315 Temperature Humidity Sensor
DESCRIPTION
e Texas Electronics, Inc. Model TTH-1315 Sensor utilizes a Vaisala HMP60 Humidity Temperature Probe with
interchangeable sensing elements that do not require calibration.
e unit is encased in a corrosion-resistant aluminum radiation shield that allows for wind aspiration and protection
from the sun’s UV rays. e shield is nished in white powder-coat to provide for virtual cosmetic invisibility while
reecting much of the radiant heat from surrounding objects and the sun.
Overcurrent protection is provided in a NEMA 4X enclosure that is mounted to the angled mounting bracket on the
sensor. Tranzorbs are utilized to protect the sensor and signal conditioning units in an overcurrent situation.
With DC voltage applied to the sensor, the unit will return signal voltages that are linear to the range of the instrument. Signal conditioning is applied to ensure proper voltages are returned and can be amplied or modied to a
current output to connect to any analog signal processing unit.

FEATURES & BENEFITS
• Combines temperature and humidity in one sensing unit
• Vaisala HMP60 has interchangeable sensing elements requiring no calibration
• Stacked plate construction of shelter provides natural ventilation
• Quick-release mounting bracket allows for easy installation and maintenance
• Aluminum radiation shield is lightweight and extremely durable
• White powder-coat nish reects most radiant heat from sun and surrounding objects
INSTALLATION & MAINTENANCE
e radiation shield with sensing element can be pole or mast mounted. Whenever possible, sensors
should be installed at a height of 4 . (1.2 meters) or greater over earth or sod at least 100 . (30.48
meters) away from any concrete or other hard-surfaced area and not closer to any other object than four
times the height of the object above the instrument shelter or remote sensors. Avoid roof installations if
possible. If it is necessary to roof-mount shelters and sensors, they should not be closer than 30 . (9.14
meters) to any large, vertical reecting surface (walls, etc.), exhaust fans, or cooling towers. Electronic remote sensors, when roof-mounted, should be installed at least 9 . (2.74 meters) or greater above the roof
surface. To minimize radiation eects from the roof, they can also be mounted on a horizontal boom so
they extend from the side of the building roof or tower assembly.
