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 interference, FEATURES AND BENEFITS Low power consumption (ICC 50A @ 5.0 Vdc) High frequency response (10 kHz) Stable TTL output (50% duty cycle) External magnetic field interference detection Harsh environment resistance Robust design, long life span Easy to install High accuracy, good stability
Supply voltage 2.7 Vdc ~ 5 Vdc Current consumption 50 A Operating magnetic field OP~10 Gs, RP~ -5 Gs Response frequency 0 Hz ~10 kHz Output interface TTL Duty cycle 50% ± 20% External magnetic field interference signal High – No Interference Low – Interference detected Operating temperature -40 ~ 100 ℃ Housing Dimensions Customizable APPLICATION EXAMPLE PIN CONFIGURATION Red Vdc+ Black Vdc- Blue TTL signal White magnetic interference signal Sensing direction Sensing distance L= 6 mm Magnet dimension:33 Magnetization direction
