Relative Humidity and Air Temperature
S1276W / S1276Z / S1276ZR
Very rugged
+/- 3% RH accuracy
+/- 0.6°C temperature accuracy
The relative humidity and air temperature
sensor is compact and easy to use. The relative
humidity element is a hygroscopic capacitive
type. It is fully interchangeable. These
elements never need calibration. Instead,
elements can be easily replaced without
the expense and inconvenience sometimes
associated with the calibration process. The
membrane filter/mechanical housing of the
sensor protects it from dust and dirt.
Includes Thermilinear Bead for air temperature
measurement.
Advantages of using a thermistor:
Sensitivity – A thermistor is much more
sensitive to temperature change than the
alternative measurement components.
Interchangeability – There are several reasons
for the ability to achieve such tight
interchangeability specifications:
– One is the ability to control the manufacturing
process precisely.
– Another is the sensitivity of the device
itself, which allows for great resolution in
the measurements.
