Rotational speed monitor with alarm
± 0.01 % RS232, 20 mA / 10 V, | 224.1S2
Braun Industrie-Elektronik
This section utilizes the pulse train, as provided by the A5S40 ..43 sensors, and additionally by the frequency trace of the A5S30..33.
It uses the advantageous measuring principle, distinguished by quartz controlled pulse distance evaluation, automatically extended over a programmable minimum period of time. The ideal combination of fast response and averaging of measurements, as appropriate for the application.
By the 5-digits scaling facility, any required reading can be established.
Measuring accuracy ± 0.01 % ± 1 in last significant digit.
Minimum time extension for every measuring period programmable 30 millisec up to 10 seconds.
The programmable low end of the speed range determines the opposite mentioned zero speed criterion selectable for the direction signal.
Display
5 digit, with bright red figures, 14 mm high. Decimals and blank zeroes can be programmed. The display update sequence may be increased beyond the minimum measuring period.
During the programming phase, the display reads the step number and its corresponding parameter.
Direction indicated by a red LED on/off.
