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.
