Sensors and Accessories

ET Manager Cartridge incorporates a rain gauge input, for optional local rain fall measurement. Rain Bird offers the ETM-RG tipping bucket rain gauge as an accessory to the ET Manager Cartridge. The tipping rain gauge is an ideal complement to the ET Manager Cartridge, this electronic gauge accurately measures rain to 1mm per tip, reducing run-off from over-watering and avoiding landscape damage. The rain gauge is durable, weatherproof, and resists UV and extreme temperatures. Measurements per tip are accurate, with a maximum +/- 2% deviation. Each gauge includes a 30’ cable.

Rain Bird also offers a remote mounting kit, ETMRMK, so that the antenna can be remotely mounted to improve signal reception or remotely locate the antenna to prevent vandalism. The kit contains a 30’ (9,1 m) cable, connector and junction box. The cable must be installed in conduit for outdoor applications.
