Speed transmitter PRE420H
PRE420H is an industrial vibration transmitter designed to monitor the condition of rotating machinery such as motors, pumps, fans and compressors. This device converts mechanical vibrations into a standard 4-20 mA current signal, proportional to the vibration velocity (in mm/s), which allows its direct integration with control and monitoring systems such as PLCs o SCADAs.
