Outline
The KS-19F is a sensor which uses the light scattering method for measuring
the particle number concentration in liquid. The particle count is determined
for various sizes. Sample fl uid contacting parts are made of sapphire and PFA,
allowing direct measurement of hydrofl uoric acid.
By connecting the KS-19F to the optional controller KE-40B1, a liquid-borne
particle counter system with up to ten size ranges can be created.
Using the KE-40B1, it is also possible to freely specify the size ranges 0.03
μm to 0.13 μm for particle detection. The factory default setting is four chan-
nels (≥0.03 μm, ≥0.06 μm, ≥0.1 μm, ≥0.13 μm).
The fl ow rate is 10 mL per minute, and counting effi ciency is 5%. The effec-
tive fl ow rate at which particles are detected and measured is the fl ow rate
multiplied by the counting effi ciency, i.e. 0.5 mL per minute.
The KS-19F does not have measurement controls or a display for measure-
ment results. It is designed to be used under control of a separate controller
KE-40B1 which also supplies power to the KS-19F.
The KS-19F incorporates a leak sensor. If a leak is detected, an alarm output
can be activated.
As the KS-19F does not incorporate a fl ow control circuit for the sample
fl uid, the fl ow rate of the sample fl uid must be controlled by external means.
Light source service life
The KS-19F uses a diode pumped solid state laser as a light source.
The life expectancy of a laser diode for pumping is shorter than that of other
semiconductors. When the laser diode nears the end of its service life, the
optical power falls below the rated level. There are considerable differences
in service life between individual diodes.
The KS-19F detects when the laser diode no longer provides the required
output. In such a case, the LASER indicator of the KS-19F and the [LASER]
icon of connected controller KE-40B1 display fl ash in green, which indicates
that the laser diode must be replaced.
