Submersible water level gauge

Submersible water level gauge

**Overview** The TD8000 series is a two-wire submersible level gauge that uses a high-precision semiconductor pressure sensor for water level detection. Despite its slim body, it has a built-in amplifier, eliminating the need for an external converter. The detection unit can be directly suspended in water or placed on the bottom, measuring the water head pressure on the diaphragm with the semiconductor pressure sensor, which converts it into a current signal for transmission. **Features** - Pressure detection type using a semiconductor pressure sensor - Built-in amplifier, two-wire (4-20 mA) - No need for a hanging chain as the wire is internally housed within the cable - Stable installation when placed on the bottom with a detection unit stand attachment - Built-in lightning protection circuit, resistant to lightning surges - TD8300 (high precision type, accuracy ±0.10% F.S.) - TD8200 (slim type, outer diameter Ø14mm) For deep wells Ø14mm with built-in amplifier.
