Frequency Transmitter FT 20

          Frequency Transmitter FT 20accepts pulse rate input from turbine meter, contact closures , proximity switch , magnetic shaft speed pickup and other frequency generating devices. Output is proportional to input frequency in standard current or voltage signal. Output ripple is less than 10 mv. Peak-to-peak to meet requirements for direct input to a process computer.
