Dwyer 641RM-12 Air Velocity Transmitter w/ 6' Cable

• 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.
• Longer cable lengths are available for ducts that are at very high elevations from the plant floor.
• The optional LED produces a complete, compact solution for local indication of air flow.
