商品説明
The OMWT-VIB series has been discontinued. Please see the OM-CP-SHOCK101 as possible alternatives or contact our Data Acquisition Engineering department.
The OMWT-VIB Wireless Vibration
Transmitter is a battery operated
digital vibration sensor with a
microprocessor controlled 418 MHz
FCC certified radio transmitter. This
transmitter is useful in applications
that need to sense when vibration
is present or not or exceeds a
threshold, e.g., to determine
whether or not an engine is
running. The OMWT-VIB has an on
board time of day clock that allows
it to spend most of the time in a low
power quiescent state. At pre-determined
time intervals the clock
will wake up the onboard micro-processor.
Unique serial number
information and digital vibration
data is combined with a CRC-16
error check and transmitted in a
very short data packet that results
in a transmitter on time of only 15
milliseconds. This architecture
allows the OMWT-VIB to consume
very low energy resulting in a
battery life of up to 2 years.
The electronics are coated with a
conformal rubber material that
provides a moisture barrier against
condensation. Submersion in water
is not recommended. An integral
pushbutton is used to activate the
service switch. The OMWT-VIB is
shipped with the transmitter turned
off (anytime the device is to be
shipped the transmitter should be
turned off or must be placed in a
shielded container to prevent
interference that might cause
shipping problems).
Start the device by momentarily
pushing the service switch (you
will feel the button click). When
the service switch is pushed, a data
transmission occurs immediately
and a special mark is introduced in
the ID field of the transmitted data
packet to indicate which device is in
service or installation. The service
switch is also used to put the device
in a quiescent mode (no trans-missions
and very low power
consumption). This is the state the
device is in when you receive it.
Push and hold the service switch for
10 seconds or more to enter this
powered down state.
Using the OMWT Series Windows
software incoming data being
received from OMWT Series
Wireless Transmitters can be
viewed in a real-time or historical
time-base chart or numerical view.
High/low alarms can also be set for
each transmitter signal with either a
visual or audible alarm indication on
the PC. Data can also be logged to
disk at a user-specified rate in a text
file format that can be opened up
into Microsoft Excel. The OMWT
Series Windows software also
includes a DDE Server that can
interface the data being received
from OMWT Series Wireless
Transmitters to other Windows
software packages.
