产品描述
The OM-CP-RFPULSE101A Series has been discontinued. Please see the OM-CP-RFPULSE2000A as
a possible alternative or contact our Data Acquisition Engineering department.
The OM-CP-RFPULSE101A is a
low-cost transmitting device that will
sense a pulse input or contact
closure from external sources such
as transducers or pulse initiators
(gas, water, and electric meters)
and transforms those inputs into
engineering units such as
gallons/minute. Once activated, the
OM-CP-RFPULSE101A senses
and transmits the number of pulses/
contact closures that occur within
adjacent "time bin" periods. The bin
period is 30 seconds to 12 hours. At
the end of each bin period, the total
number of pulses/counts is transmitted.
The OM-CP-RFPULSE101A
then starts another bin period. It will
also transmit the current status of its
input. This is ideal for recording the
status of a contact closure. Data is
received at the PC using our
receiving antenna that attaches
directly to the serial port. All
received data is time and date
stamped and stored directly in your
PC. Transmitted data is also logged
to the device’s memory for added
data security. The convenient slide
switch allows the transmitter to be
turned On or Off without affecting
the operation of the device.
The Windows software converts
your PC into a real time strip chart
recorder. Data can be printed in
graphical or tabular format and can
also be exported to a text or
Microsoft Excel file.
