Model No. : |
090D,091 |
| |
|
Description : |
Convert absolute atmospheric pressure into a linear, proportional voltage, which may be used in
any meteorological program. These sensors are inherently
stable devices that do not
require periodic service or
routine recalibration.
Operation:
The enclosure houses a solidstate
pressure transducer, with
linearization and amplification
electronics.
The Model 090D is housed in a
heavy duty fiberglass enclosure,
suitable for harsh and severe
environments. A hose barb is
provided to enable the connection
of a 1/4” sampling tube to
the outside environment.
The Model 091 is contained
within a small polycarbonate
enclosure, and may be mounted
outside or inside a building
or other enclosure. Small inlet
holes allow the atmospheric
pressure access to the
sensing element.
The standard range of the 090D/ 091 is 26-32 in. Hg,*
suitable for elevations sea
level to 1500 ft. Other ranges
are available. |
