Fully waterproof, low cost type, ideal for water level and water pressure sensors

Features

1. Immersion-type
2. Water pressure measurement

• When used as an immersion-type water level sensor :

1. Ideal for water level observation for water channels, groundwater, reservoirs, tanks, etc.
2. Measurement to an accuracy of millimeters possible
3. Need for atmospheric correction eliminated by the built-in atmospheric relief pipe

• When used as a water pressure sensor :

1. Full waterproof type with the IP68 structure with high environmental resistance Air release possible with a sealed screw
2. Wide range of positive pressure, negative pressure, and compound pressure

• Output signal of 1 to 5 VDC or 4 to 20 mADC from a built-in amplifier circuit
