Rotational speed sensor
Rheintacho has released the FE PWM rotational speed sensor from the FE series. The sensor is small in size in connection with the housing diameter and length as well as the space requirements above and below the flange. The main area of application for this sensor is in hydraulic drives, especially for construction and agricultural equipment. The sensor achieved the IP67 and IP6K9K ratings. This means dirt, moisture and intensive cleaning methods are no problem for the sensor. The housing is made of a special brass alloy.
This sensor adds a rotational direction signal to the rotational speed signal.The electronic design with a pulse-width modulated signal (PWM) works with a current signal differing from the 1-channel and 2-channel version, on which the rotational direction information is transmitted through the differing pulse lengths. At the same time, this sensor also provides a signal with a constant amplitude independent from the rotational speed. This sensor not only detects rotational speed and direction, but also provides additional diagnostic functions, e.g. downtime recognition, critical air gap and critical installation position.
