TE525 Tipping Bucket Rain Gage 5. Overview The TE525-series tipping bucket rain gages funnel precipitation into a bucket mechanism that tips when filled to a calibrated level. A magnet attached to the tipping mechanism actuates a switch as the bucket tips. The momentary switch closure is counted by the pulse-counting circuitry of Campbell Scientific dataloggers. The TE525-series tipping bucket rain gages are manufactured by Texas Electronics and then cabled by Campbell Scientific. The -L after the model number indicates the cable length is specified when ordered. The cable can terminate in: • Pigtails that connect directly to a Campbell Scientific datalogger (option -PT). • Connector that attaches to a prewired enclosure (option -PW). Refer to www.campbellsci.com/prewired-enclosures for more information. • Connector that attaches to a CWS900 Wireless Sensor Interface (option -CWS). The CWS900 allows the probe to be used in a wireless sensor network. Refer to www.campbellsci.com/cws900 for more information. • Connector that attaches to a CS110 Electric Field Meter or ET-series weather station (cable termination option -C). • Military-style connector that attaches to a RAWS-P Permanent Remote Automated Weather Station (cable termination option -RQ). This option is not available for the TE525MM. 5.1 Wind Screen Campbell Scientific offers the 260-953 Wind Screen to help minimize the effect of wind on the rain measurements. This wind screen consists of 32 leaves that hang freely and swing as wind moves past them. Refer to the 260953 manual for siting information and the installation procedure. 5.2 Snowfall Adapter Campbell Scientific's CS705 Snowfall Conversion Adapter uses antifreeze to melt snow, allowing the TE525WS to measure the water content of snow. The CS705 cannot be directly used with either the TE525 or TE525MM. However, both the TE525 and TE525MM can be converted to a TE525WS by returning them to Campbell Scientific (see Assistance page at the beginning of this document). Refer to the CS705 manual for siting information and the installation procedure. 7

TE525 Tipping Bucket Rain Gage
5.
Overview
The TE525-series tipping bucket rain gages funnel precipitation into a bucket
mechanism that tips when filled to a calibrated level.
A magnet attached to the
tipping mechanism actuates a switch as the bucket tips.
The momentary switch
closure is counted by the pulse-counting circuitry of Campbell Scientific
dataloggers.
The TE525-series tipping bucket rain gages are manufactured by Texas
Electronics and then cabled by Campbell Scientific.
The –L after the model
number indicates the cable length is specified when ordered.
The cable can
terminate in:
•
Pigtails that connect directly to a Campbell Scientific datalogger
(option –PT).
•
Connector that attaches to a prewired enclosure (option –PW).
Refer
to
www.campbellsci.com/prewired-enclosures
for more information.
•
Connector that attaches to a CWS900 Wireless Sensor Interface
(option –CWS).
The CWS900 allows the probe to be used in a
wireless sensor network.
Refer to
www.campbellsci.com/cws900
for
more information.
•
Connector that attaches to a CS110 Electric Field Meter or ET-series
weather station (cable termination option –C).
•
Military-style connector that attaches to a RAWS-P Permanent
Remote Automated Weather Station (cable termination option –RQ).
This option is not available for the TE525MM.
5.1
Wind Screen
Campbell Scientific offers the 260-953 Wind Screen to help minimize the
effect of wind on the rain measurements.
This wind screen consists of 32
leaves that hang freely and swing as wind moves past them.
Refer to the 260-
953 manual for siting information and the installation procedure.
5.2
Snowfall Adapter
Campbell Scientific’s CS705 Snowfall Conversion Adapter uses antifreeze to
melt snow, allowing the TE525WS to measure the water content of snow.
The
CS705 cannot be directly used with either the TE525 or TE525MM.
However,
both the TE525 and TE525MM can be converted to a TE525WS by returning
them to Campbell Scientific (see
Assistance
page at the beginning of this
document).
Refer to the CS705 manual for siting information and the
installation procedure.
