Campbell Scientific TE525MM-L – Metric Rain Gage with 9.6 in. Orifice
Overview
The TE525MM, manufactured by Texas Electronics, is a tipping bucket rain gage that monitors rainfall in metric rather than US units. It measures in 0.1 mm increments and has a 24.5 cm funnel. This tipping bucket is compatible with all Campbell Scientific data loggers, and is widely used in environmental monitoring applications.
Benefits and Features
- Accuracy is ±1 percent at rates up to 1 in./hr
- Compatible with most Campbell Scientific data loggers
- High precision—tips at 0.1-mm increments
- Compatible with the CWS900-series interfaces, allowing it to be used in a wireless sensor network
- Includes a 24.5-cm funnel, which is the largest diameter funnel of the TE525-series raingages
Detailed Description
The TE525MM funnels precipitation into a bucket mechanism that tips when filled to its 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 our data loggers.
