Optical Fiber Liquid-Level Sensor
The Series 1010 synthetic optical-fiber sensor does contact-level detection in all nonmilky-white liquids.
The unit
features an AISI 303-stainless-steel
housing, a scratch-resistant
glass prism, and fully potted
optical parts for an IP68
protection level making it
impervious to most harsh
liquids. Two individual fibers with an
outside diameter of 2.2 mm and an
inner fiber of 0.5 mm give high resolution
to liquid- level measurements.
The standard 2-m cable can be cut
to length for neater appearance and
safety considerations. The fiber material
is PMMA with a sleeve of PE and a
fiber-bending radius of 25 mm. Ambient
operating temperature is from
–25 to 70°C
