Liquid Type Identiﬁcation Sensor
ES-5000 Series

Can you check
what the liquid is?

Liquid Identiﬁcation Sensor
Since the Liquid Type Identiﬁcation Sensor detects variation in numerical values according to liquid type and / orconcentration, it is possible to identify the liquid type even it cannot be identiﬁed visually, and detect liquid leakage inenvironment where water is constantly present.
Also, when the value ﬂuctuates due to a change in the liquid, a signal can be output by freely setting the thresholdvalue. (There are 2 output signals.)
Furthermore, by using an optical ﬁber for the detection unit, it can be used in an explosion-proof area and the liquids
that there is a risk of explosion.

Example of use
Liquid leak sensor that can distinguish between water and other liquids
In the case of outdoor piping, it is possible to detect and warn of liquid leakage from the piping without detecting itwith rainwater.
This application is possible only with Liquid Identiﬁcation Sensor that can distinguish between water and other liquids.

Normal Operation

In rainy weather
In case of leakage in rain

Liquid level management and Liquid Identiﬁcation in the tank
If installed in a certain position (level), the sensor is enable to use as a liquid level sensor.
By utilizing the liquid type identiﬁcation function, it is no longer just a liquid level sensor. Example, this sensor candistinguish between "a moderately mixed liquid state" and "a liquid in which the liquid separates and the oil ﬂoats overtime".

Detection Principle
In a normal situation, the light emitted from the control unit passes
through the detection unit and returns without reducing the amount oflight. However, when the liquid touches the detector, the light istransmitted toward the liquid and the amount of light to control unit
decreases.
Since the rate of decrease in the amount of light differs depending on thetype of liquid, the mechanism is such that the rate of decrease in theamount of light is quantiﬁed and discriminated.
