SENSORS AND FILTERS
HUMICAP
®
Sensors: Replacement HUMICAP
®
sensors are
available with and without membrane filters. The type of
replacement sensor recommended will depend on both the
instrument in use and its operating conditions. Refer to the
specific instrument data sheet for the appropriate replacement
sensor, or contact Vaisala for assistance.
Protective filters: Filter selection is important. Apart from
screening the sensor head from any stray electromagnetic
fields, the main purpose of the filter is to protect the sensor.
If the environment is clean and a particularly fast temperature
response is required, then an open cage grid can be used.
Otherwise a membrane or netting filter is recommended for
the majority of applications. When saturated, membrane or
netting filters dry out faster than sintered ones. For tempera-
tures above 176°F (80°C) or when there is a risk of damage
from fast moving particles, then a sintered or stainless steel net
filter should be used.
Vaisala probe heads can be installed in air streams with speeds
up to 40 meters per second when fitted with the appropriate
sintered filter.
Membrane filters:
Part # 2787HM ø 18.5mm, 0.5 µm
Part # 10159 ø 12.0mm, 0.5 µm
Filters for INTERCAP products:
Part# 15724 metallized plastic grid (non-filtering) ø 12 mm
Part# 16131 metallized membrane filter ø 12.0 mm, 0.5µm
Sintered bronze filters:
Sintered bronze filters are useful where mechanical strength is
necessary, in very dusty environments, or at extremely high
temperatures. Three options are available:
Part # 0195 HM ø 12 mm, 133 µm
Part # 6685 HM ø 18.5 mm, 37 µm
Part # 6686 HM ø 18.5 mm, 216 µm
Filters for the HMP 230 & HMP 360 series:
Part # 16452 sintered filter ø 13.5 mm, 38 µm
Part # 16720 PPS grid w/stainless steel net ø 13.5 mm, 14 µm
Part # 16562 PPS grid (non-filtering) ø 13.5 mm
Part # 16720 PPS grid w/membrane filter ø 13.5 mm, 2 µm
