Page 5: General Information
This manual is intended as a general guide for installing, wiring and using the SBS range of rain gauges. There are three models of SBS gauge, but the guidelines for each are the same so the generic term of reference used is ‘SBS’. The information contained in this manual may not cover all aspects of SBS applications. -
Page 6: Introduction
The gauge should ideally be no closer than at least twice the height of the obstruction. Although the SBS rain gauge is designed to operate in higher wind speeds, care must still be taken to avoid over-exposing the gauge where possible. -
Page 7: Levelling The Rain Gauge
There are options which can be used to mount the SBS above the ground. The SBS can be purchased with a rain gauge pedestal and guy kit or a rain gauge pedestal only. An example of this configuration is shown in Figure 2. -
Page 8: Wiring Guidelines
Figure 2 - SBS500 fitted to a pedestal as part of the EML system 4. Wiring Guidelines This section gives information on the wiring of SBS rain gauge. For most applications, the rain gauge may be connected directly to a pulse counting input (contact closure) on a data logger, but some care is needed if long cables are used. -
Page 9: Field Replaceable Dual Reed Switches
Field replaceable dual reed switches SBS gauges are fitted with dual reed switches. This means that 2 data outputs can be logged using the same tipping bucket mechanism. It is an important feature providing built-in redundancy which is often critical for professional users such as National Meteorological Services. Another feature of the reed switches is that they are replaceable in the field. -
