LSW/LSM
Air flow monitor – Air flow transducer, electronic, single-stage
Application
The LSW/LSM is used for monitoring air flows in ducts, on fans, control dampers, for flow-dependent monitoring of humidifiers and electric heating coils in accordance with DIN 57100 Part 420 or for use in conjunction with control units.
