Pipe-mountable Liquid Level Detection Sensor Other Products FT-Z8Y Chemical-resistant FD-F4/F9 FD-F8Y EX-F1 Liquid Leak / Liquid Level Sensing SENSORS FOR SEMICONDUCTOR INDUSTRY EX-F1 SERIES Amplifier Built-in Reliable liquid level detection with amplifier built-in low-priced sensor Conforming to EMC Directive Space-saving amplifier built-in type Low price Easily mountable and adjustable EX-F1 amplifier built-in sensor saves space as there is no need to install a separate amplifier. EX-F1 is very cost-effective. 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. Release lever Position adjustable Easy to check operation Indicator Operation mode switch The operation can be checked at a glance from different directions. 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. Operation indicator (Red) Lights up when the output is ON. ( ) 608 Detecting liquid level in a tank Principle of Detection When the pipe is empty, the beam is reflected from the inner surface of the pipe wall and returns to the beamreceiving part, since the difference in the refractive indexes of the pipe and air is large. When there is liquid in the pipe, the beam enters the liquid through the wall and does not return to the beamreceiving part, since the difference in the refractive indexes of the pipe and the liquid is small. EX-F1 The beam passes through the wall into the liquid. Chemical-resistant FT-Z8Y The beam reflected from the inner surface of the pipe wall returns to the beam-receiving part.

Make sure that the release lever is retracted (position as in the figure) before mounting. Fasten two tying bands, as shown, and cut off the excess portions. Anti-slip tube Upper side Tying band Selecting output operation • Either Light-ON (Liquidabsent-ON) or Dark-ON (Liquid-present-ON) can be selected with the operation mode switch according to your application. Operation indicator (Red) Lights up when the output is ON Operation mode switch L: Light-ON (Liquid-absent-ON) D: Dark-ON (Liquid-present-ON) • The indicator operation and the output operation change with the setting of the operation mode switch as given in the table below. Lower side Release lever • If other tying bands are to be used, the dimension @ shown in the figure below should be 2.5 mm 0.098 in or less. @ Liquid-absent Liquid-present : Lights up Position adjustment • After it is mounted on the pipe with tying bands, the sensor position can be easily adjusted. MODE ( Light-ON Liquid-absentON ( Dark-ON Liquid-presentON Adjustment 1 Unlock the release lever (in the direction of the arrow). Release lever 2 Press the movable center holders forward to loosen the tying bands and adjust the position. Position adjustable Loosen Press 3 Lock the release lever to its original place. Release lever Note: The lever mechanism must be used only to adjust the position, and not for tightening the tying bands. If tying bands are tightened while the lever is open, and then the lever is locked, the sensor may be damaged.

Outer Inner wall wall • Take care that no dew condenses Liquid drops on the pipe’s sensing surface or the pipe’s inside wall and that no bubble attaches on the pipe’s inside wall, since it can affect the operation. Bubbles • If a liquid drop flows down across the sensing point or an air bubble sticks on the wall at the sensing point, the operation may be erroneous. Make sure that no bubble arises in the liquid, and that no dew or liquid drop is present on either surface of the pipe wall. • EX-F1 is not water-proof or chemical-resistant. Installation should be avoided at any place where it could come in direct contact with water or chemicals.
