TE525 Tipping Bucket Rain Gage
Signal Output:
Momentary switch closure activated by tipping bucket mechanism.
Switch closure is approximately 135 ms.
Calibration/Cleaning Frequency:
Sensor is factory calibrated and should not require field calibration.
Debris filters, funnel, and bucket reservoirs should be kept clean. Section
6 describes field calibration check and factory calibration.
Environmental Limits:
Temperature: 0° to +50°C
Humidity: 0 to 100%
Physical Data:
Diameter: 6.25 in. overall
Height
TE525 9.5 in.
TE525WS 12 in.
TE525MM 12 in.
Weight: 2.5 pounds
Funnel: Gold anodized spun aluminum knife edge collector ring and
funnel assembly.
Funnel Collector Diameter:
TE525 6.064 in.
TE525WS 8 in.
TE525MM 9.664 in.
Resolution: 1 tip
Mounting: Side bracket with clamps for pole or mast mounting
Material: Aluminum
Cable: 2-conductor, shielded cable, length must be specified when
ordering.
The black outer jacket of the cable is Santoprene ® rubber. This
compound was chosen for its resistance to temperature extremes,
moisture, and UV degradation. However, this jacket will
support combustion in air. It is rated as slow burning when
tested according to U.L. 94 H.B. and will pass FMVSS302.
Local fire codes may preclude its use inside buildings.
NOTE
5.3. Installation
The 260-953 Alter-Type Wind Screen’s siting information and
installation procedure are provided in our 260-953 manual.
NOTE
5.3.1 Siting
The rain gage should be mounted in a relatively level spot which is
representative of the surrounding area. The lip of the funnel should be
horizontal and at least 30 cm. above the ground. It should be high enough to
be above the average snow depth. The ground surface around the rain gage
should be natural vegetation or gravel. It should not be paved.
