SI-111

Product Introduction:

The SI-111 is an unamplified analog voltage output sensor with a field of view Angle of 22°30 'and a response time of 0.6s. The sensor includes an IP68 Marine grade stainless steel cable connector, which is located at the head of the sensor, simplifies sensor removal and replacement, and is easy to maintain and recalibrate.

Typical applications:

Temperature measurement of plant canopy for estimating plant water state;

Temperature measurements of road surfaces used to determine icy conditions;

Temperature measurements of land surfaces (soil, vegetation, water, snow) for energy balance studies.

Technical parameters:

Sensitivity: 60uV /℃

The thermopile output has a voltage of -3.3mV to 3.3mV corresponding to a temperature of -55 ° C to 55 ° C. The output thermistor ranges from 0 to 2500mV. (Typically, depending on input voltage)

Excitation voltage: 2500mV(typical)

Measurement range: -60℃-110℃, calibration uncertainty (-20℃-65℃)0.2℃; When the temperature of the target and detector is 20℃, the calibration uncertainty (-40℃-80℃) is less than 0.5℃; when the temperature difference between the target and detector is more than 20℃, the measurement repeatability is less than 0.05℃

Stability (long-term drift) : When the germanium filter is kept clean, the slope change is less than 2% per year

Response time 0.6s (when the detector signal reaches 95% of the time)

Field of view: 22˚30 '

Spectral range: 8 to 14µm; Atmospheric window

Operating environment: -55℃ to 80℃; 0 to 100% relative humidity (non-condensing)

Diameter 23 mm, length 60 mm

Weight: 190g (including 5m lead)

Cable 5m four-core shielded twisted pair TPR jacket (high water resistance, high UV stability, flexibility in cold conditions), can be attached to the cable

Warranty 4 years
