DESCRIPTION
FSD
TMR1005 is a fast frequency response, low power consumption, moisture and water proof rotational
speed sensor, incorporating high sensitivity tunneling magnetoresistive (TMR) sensor, signal processing circuit
and stainless steel housing. It is an ideal solution for industrial turbine meter and lobed impeller flow meter
applications which requires low power consumpt ion, fast frequency response and harsh operating
environment.
FSD
TMR1005 rotational speed sensor measures the flow rate by detecting rotational velocity of turbine rotor
in turbine meter or impeller in lobed impeller flow meter. It provides rotational ve locity measurement and
external magnetic field interference detection functions. FSD TMR1005 outputs TTL digital square wave signal
with the frequency proportional to the rotation speed It also outputs alarm signal when detecting external
magnetic field i nterference,
