LEAK SENSOR
Amplifier built-in
High-speed Detection Even Little Chemical Leak
Reliable Detection
unique effect capillarity enables reliable detection small leaks viscous liquids.
Safe Design
sensor mounted correctly, cable disconnected, sensor operating correctly, output same when beam received (LEAK). Design deals with human errors such forgetting mount, etc.
Capillarity effect
Liquid
Fiber head
Easy Operation Check
This sensor equipped with NORMAL indicator (green) which lights when mounting correctly, FAULT indicator (red) which lights when sensing leaked liquid when mounted incorrectly (forgetting mount exclusive mounting bracket). operation checked easily.
Leakage
Need Sensitivity Adjustment Compact, Space-saving
This slim (10mm) side-mounting sensor especially good confined spaces. need sensitivity adjustment with adjuster, initial mounting easy.
Easy Installation Reset
10mm approx.
Bracket mounted with screw, one-touch sensor mounting. resetting component replacement required after leak detection. simple shape makes easy wipe leaked liquid.
Type Detection Method When leak occurs, beam form beam-emitting part scatters through leaked liquid transmitted beam-receiving part.

Sensing surface
When leakage occurs beam from beamemitting part scatters through leaked liquid transmitted beam-receiving part.
Leakage
Sensing surface
When there leakage beam from beamemitting part reflects surface sensor transmitted beam-receiving part.

Mounting Wiring
This product safety sensor. intended designed protect life prevent body injury property damage from dangerous parts machinery. normal object detection sensor.
sure mounting bracket when installing sensor avoid human error. Reliable detection cannot guaranteed when this mounting bracket used. Tightening torque mounting bracket should 0.98N less. Make sure carry wiring power supply condition. Verify that supply voltage variation within rating. Take care that voltage exceeding rated range applied, power supply directly connected, sensor burnt damaged. power supplied from commercial switching regulator, ensure that frame ground (F.G.) terminal power supply connected actual ground. case noise generating equipment (switching regulator, inverter motor, etc.) used vicinity this product, connect frame ground (F.G.) terminal equipment actual ground. Extension total possible with 0.3mm2, more, cable. However, order reduce noise, make wiring short possible. wires together with high-voltage lines power lines them same raceway. This cause malfunction induction. Ensure that isolation transformer utilized power supply. autotransformer utilized, main amplifier power supply damaged. case surge generated used power supply, connect surge absorber supply absorb surge.

Notes: Highly viscous liquid detected stably. Liquid being detected should also kept within rated ambient temperature range.

bubbles trapped within sensing portion, take care that extra time required obtain stable sensing, stable sensing achieved. Before use, thoroughly check conditions under which sensor used. proper treatment after liquid leak, ensure that liquid completely wiped from both sensor's sensing surface from mounting bracket. soft cloth must used ensure that scratches other damage occur. sensing surface mounting bracket scratched, traces liquid remain, then normal functionality will impaired. during initial transient time sec. approx.) after power supply switched Since sensor non-modulated type, take sufficient care against extraneous light. Make sure that extraneous light directly incident sensing surface. These sensors must used locations containing high levels steam dust, used within dangerous atmospheres, such those containing corrosive gases. Take care that product does come direct contact with organic solvents, such thinner, etc. these sensors used environment where static electricity generated, then used contain liquid leaks must made metal connected proper electrical ground.
