Introduction
The PS-2109 Sound Level Sensor measures both sound level
in decibels and sound intensity in microwatts per square
meter. The sensor measures sound level in both the dBA
weighting scale (matching the sensitivity of the ear) and the
dBC weighting scale (equal response to all frequencies). The
sensor has three selectable sound level ranges. The sensor is
designed to measure sound levels of sources within 10 feet
(3.04 m).
The sensor includes a Sensor Mounting Stud that can serve
as a handle or mounting rod when it is screwed into the
1/4-20 threaded hole on the side of the sensor box. The
non-threaded end of the stud fits on the shaft of a PASCO
Rotary Motion Sensor.
The sensor is designed to work with a PASPORT-compatible
interface (such as the UI-5100 850 Universal Interface) and
PASCO data acquisition software (such as PASCO Capstone
or SPARKvue) to measure sound level and sound intensity.
Sensor Setup
•
Plug the sensor into a PASPORT input port of a PASCO
interface.
NOTE: If more distance is needed between the sensor and
the interface, plug the sensor into a Sensor Extension Cable
(PS-2500), and then plug the cable into the interface.
