Speed measurement converter with alarm
RS232 - RS485 | 124.1S6
Braun Industrie-Elektronik
*
1 speed measuring channel with additional facility to compute
the rotational acceleration from subsequent speed measurements.
*
Programmable for conversion into analogue signal, controlling the setpoint alarms, and the display.
*
Compatible with all our high level speed sensors, and other speed transmitters of corresponding type.
*
Specifically preferred for use with power plant turbines in order to observe the required mode of operation, and as an additional warning of impending danger.
Measuring Principle
Using the advantageous quartz controlled pulse distance evaluation, automatically extended over a programmable minimum period of time. Thus determining response time and averaging of measurements to achieve a high stability of readings, as specifically required for the acceleration detection.
Digital 5-digit scaling precisely adjusts the meter to the data of the specific application.
Measuring accuracy ± 0.01 % ± 1 in last significant digit.
Minimum time extension for each measuring period programmable 30 millisec up to 10 seconds.
Special parameters adapt the unit to the performance best suited to determine the acceleration: defining the reading unit, and the number of measurements to be included into the acceleration computing cycle..
