The OM-CP-RFPROCESS101A Series has been discontinued. Please see the OM-CP-RFCURRENT2000A as a possible alternative or contact our Data Acquisition Engineering department.

The OM-CP-RFPROCESS101A is a battery powered current recorder and wireless transmitter. This is an all-in-one compact, portable, easy to use device that will measure and transmit process measurements. When enabled, the wireless transmitter will transmit readings back to the host computer where the data can be analyzed in real time. These readings are 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 device can be started,stopped and configured directly from your computer. Its small size allows it to fit almost anywhere.

In addition to the wireless communications, the OM-CP-RFPROCESS101A makes data retrieval quick and easy. Simply plug the device into an empty COM port and our user-friendly software will handle the rest. The software converts your PC into a real time strip chart recorder. Data can be printed in graphical or tabular format and can be exported to a text or Microsoft Excel file.
