Model TTH-1315 Temperature Humidity Sensor
DESCRIPTION
The Texas Electronics, Inc. Model TTH-1315 Sensor utilizes a Vaisala HMP60 Humidity Temperature Probe with
interchangeable sensing elements that do not require calibration.
The unit is encased in a corrosion-resistant aluminum radiation shield that allows for wind aspiration and protection
from the sun’s UV rays. The shield is finished in white powder-coat to provide for virtual cosmetic invisibility while
reflecting 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 instru-
ment. Signal conditioning is applied to ensure proper voltages are returned and can be amplified or modified to a
current output to connect to any analog signal processing unit.
