E8FC

Detect Signs of Abnormalities in Cooling Water by Simultaneous Measurement of “Flow Rate + Temperature”

Prevents sudden stops and molding defects due to cooling abnormalities

E8FC Features 2

Multi-sensing technology

[Flow rate] Uses the "Thermal flow rate measurement algorithm". Detect the flow velocity of the fluid by measuring how fast heat is taken from the pulse heated Ta (heated temperature measurement area), and performs flow rate calculations based on the pipe diameter.

[Temp.] Uses the platinum element in Tb (liquid temperature measurement area) to directly measure the liquid temperature.

E8FC Features 5

Welding machine

Problems

[Deformed welding tips and overheated transformers due to cooling performance degradation]

• If the cooling water temperature rises, the welding tip or welding transformer cannot be sufficiently cooled.
• If the welding tip gets overheated and deformed, welding defects occur.
• The welding transformer gets overheated, and the equipment suddenly stops.
• You cannot detect a temperature rise by monitoring temperature alone.

Solution from OMRON

E8FC Features 10

You can detect signs even before welding tip deformation or sudden stops occur

E8FC Features 11
E8FC Features 12

Molding machine

Problems

[Molding defects due to cooling performance degradation]

• Even if the amount of cooling water is adequate, a rise in water temperature leads to a drop in cooling performance.
• If the cooling performance declines, the processed part on the mold cannot be adequately cooled, resulting in deformation, voids, or other molding defects.
• You cannot detect a temperature rise by flow rate monitoring alone.

Solution from OMRON

E8FC Features 17

You can detect signs of cooling performance degradation even before occurrence of molding defects.

Monitor the "flow rate" and "temperature changes" in the same position, and quantify the optimum ranges for flow rate and temperature. You can detect signs of cooling performance degradation without relying on the experience or skills of maintenance personnel.
In addition, by mounting sensors on multiple pipes, you can quickly tell from the sensor LEDs what abnormality has occurred, in which pipe.

E8FC Features 18

Notifications of changes in the cooling water or hydraulic oil states are easy to understand

You can see the cause of the abnormality Multi-sensing display [Patent pending]

The sensor judges by monitoring "Flow rate + Temperature" and "Pressure + Temperature". Since data outputs to a PLC by the IO-Link communications is possible, it is easy to perform maintenance before entering an abnormal state. For the display colors, you can set 3 patterns, or if combined with Not lit, a total of 4 patterns.

E8FC Features 20

You can see the rate of change with a percentage Relative value display

With the flow rate at the time of setting as 100%, you can relatively measure the change in flow rate value. Smart Tuning function is convenient for cases where optimum value management of absolute values is difficult, such as when the operating environment is changing, and liquid types are changing, etc.

E8FC Features 21

You can also see the sensor status Self-diagnostic outputs

E8FC Features 22

Self-diagnoses the sensor's own status, and autonomously sends notification when signs of a connection error or a malfunction appears.

E8FC Features 23

Easy to see High luminosity LED display

A high luminosity LED gives good visibility even at the back of equipment or in dark locations.

E8FC Features 24

Easy to understand Display by unit

Converts to physical quantity units for display.

E8FC Features 25

Adjust the angle according to the mounting position

Angle adjustment up to 330°

After fastening to the adapter, you can adjust the angle so that the display is easy to see.

E8FC Features 27

180° reverse display

The display can rotate 180°.

E8FC Features 28

Easy to use in various location

Compact and space-saving

You can even mount in narrow spaces with multiple pipes arrayed.

E8FC Features 30

Direct setting

E8FC Features 31

Button on the body for quick setting. After setting, you can use the key lock function to prevent operation in error.

E8FC Features 32

Highly durable liquid contact part

E8FC Features 33

Batch setting from host devices

E8FC Features 34

During maintenance, the settings must be the same conditions as when the product was initially mounted. If you use the IO-Link function, you can perform batch setting from a host device. You can manage by quantifying the adjustment that is performed by skilled personnel to avoid affecting the manufacturing quality.

E8FC Features 35

Easy-to-clean structure

Structure is easily removable from the piping for periodic inspections, etc., and easily cleaned.

E8FC Features 36

Expanded cable and adapter lineups (sold separately)*

E8FC Features 37

* Use our dedicated adapters. In addition, if there is a possibility of pulsations or vibrations to a Pressure Sensor, we recommend the attachment of a throttle (sold separately).
