List of water level gauge products
With a built-in lightning rod for lightning surge protection Relay box TU1130
The TU1130DL and TU1200DL serve as relays for the DC 4–20 mA signal cable of the 2-wire type immersion-type water level gauge to simultaneously display the water level digitally. They also feature a built-in arrester for lightning surge protection. The TU1130DL is waterproof, enabling it to be installed outdoors near the water level gauge.
