The SERIES 641RM features the same highly accurate heated mass flow sensor as the Series 641, with a remote probe construction. The units 6´ cable which connects the sensing probe with the electronic enclosure allows the enclosure to be mounted where it can be more easily accessed.
The Series 641RM Air Velocity Transmitter uses a heated mass flow sensor technology. It has 8 user selectable ranges from 250 FPM to 15000 FPM with corresponding metric ranges of 1.25 MPS to 75 MPS. The Series 641RM Air Velocity Transmitter provides an isolated 4-20 mA output proportional to the velocity. With the optional 1/2˝ 4-1/2 digit LED display, the Series 641RM Air Velocity Transmitter will provide a highly visible local readout of the velocity.
