Main features

Detects high and low limit level of fluid using a single tube

The level when the sensor tip touches the surface is output as an Alarm.

Use of PFA tube enables measuring corrosive chemical solutions.

Highly reliable

Uses semi-conductor pressure sensor (back pressure sensor) in the sensing part. Structure without mechanical parts ensures high reliability and repeatability.

No adjustment required

Arranging for a tube with the specified length is all required.

Built-in orifice. Just supply of 20±1kPa air gas, then the specified purge flow rate is obtained.
