EX-F1

EX-F1 Liquid Level Sensor It can be used to measure the level of non-viscosity liquids or sediment mixed in Compatible with clear tubes 6 to 13 mm in diameter and up to 1 mm thick with clear indicator light, lightweight, small size, does not require a controller. And easy to install Just by attaching the sensor to the pipe in the desired position, it can be used to measure the liquid level.

Features

Space-saving amplifier built-in type

EX-F1 amplifier built-in sensor saves space as there is no need to install a separate amplifier.

Easily mountable and adjustable

Just attach it on a pipe with the tying bands. The position can be easily changed with the release lever even after mounting, so that there is no need to cut the tying bands.

 

 

Low price

EX-F1 is very cost-effective.

Easy to check operation Indicator

The operation can be checked at a glance from different directions.

 

 

Operation mode switch

Either Light-ON or Dark-ON can be selected by a switch. This is useful to check the operation during installation because it forces the output to be turned ON or OFF even without the liquid being inside the pipe.
