Sidewall Velocity Sensor (Svs) - Price Antec controls CAVA Manual

Sidewall Velocity Sensor (SVS)

The Sidewall Velocity Sensor (SVS) reports face velocity to Cava™ by measuring
the differential pressure between the fume hood and the laboratory. Cava™ uses
the SVS measurement to adjust the exhaust to meet the required face velocity. The
SVS consists of multiple components:
•
Sidewall Velocity Sensor (SVS)
•
1' x 3.5" 3M Dual Lock Fastener
•
Two brass bulkheads with vent screws
•
Two 1.5-foot lengths of high-pressure tubing
See the SVS product submittal on
Dimensions, and Wiring.
Mechanical Installation
The SVS can be mounted in one of three locations. Option A mounts on top of the fume hood, Option B mounts in the side
panelling (chase) of the fume hood, and Option C mounts in the front panelling of the fume hood.
Mounting options may be limited by tubing length and vent screw locations. It is recommended to select the mounting location
which minimizes tubing length, and to keep in mind the following considerations when selecting a location.

Option A
Mount the SVS on top of the fume hood.
•
Tubing runs over the top of the fume hood and down the side panelling (chase) and
should not exceed 2 feet.
•
Must ensure tubing and wiring do not interfere with the mechanical operation of the
fume hood sash.
Option B
Mount the SVS in the side panelling (chase) of the fume hood.
•
Exterior wall of chase is often removable for maintenance. If sensor is mounted to
this wall, it will need to be disconnected for removal.
•
Ideal mounting location is on interior wall above the inside wall access panel.
Option C
Mount the SVS in the front panelling of the fume hood.
•
Tubing runs from front panelling to side panelling, which may require passthrough
holes to be drilled depending on fume hood design.
