TE525 Tipping Bucket Rain Gage
1. Introduction
The TE525 Tipping Bucket Rain Gage is an adaptation of the standard
National Weather Service tipping bucket rain gage. It outputs a switch closure
for each bucket tip. Three models are available:
• TE525 6 in. orifice 0.01 in. tip
• TE525WS 8 in. orifice 0.01 in. tip
• TE525MM 24.5 cm orifice 0.1 mm tip
2. Cautionary Statements
• READ AND UNDERSTAND the Precautions section at the front of this
manual.
• TE525-series tipping bucket rain gages are precision instruments that must
be handled with care.
• Sensor is factory-calibrated and should not require field calibration. Refer
to Section 9.2, Maintenance, for field calibration check and factory
calibration.
• Debris filters, funnel, and bucket reservoirs should be kept clean.
• Santoprene
®
rubber, which composes the black outer jacket of the TE525
cable, will support combustion in air. It is used because of its resistance to
temperature extremes, moisture, and UV degradation. It is rated as slow
burning when tested according to U.L. 94 H.B. and passes FMVSS302.
However, local fire codes may preclude its use inside buildings.
3. Initial Inspection
• Check the packaging and contents of the shipment. If damage occurred
during transport, immediately file a claim with the carrier. Contact
Campbell Scientific to facilitate repair or replacement.
• Check model information against the shipping documents to ensure the
expected products and the correct lengths of cable are received (see
Section 3.1, Ships With). Model numbers are found on each product. On
cables and cabled items, the model number is usually found at the
connection end of the cable. Report any shortages immediately to
Campbell Scientific.
