656 series

Measuring channels : 1

Main alert

Suitable for : HE100 series

The Type 656 evaluation component is used to detect and evaluate current signals, 4...20 mA, of vibration monitoring units in two-wire technology. The switching threshold and the delay time can be adjusted on the evaluation component. If the signal exceeds (type 656-A) or undershoots (type 656-B) the switching threshold and the delay time has, this is indicated at the outputs by LEDs and relays. Cable breaks and a lack of power are indicated in the same way. These signals can be used to generate an alarm.

  • Vents


    Fans are used successfully in almost all sectors of industry. Status monitoring helps to prevent faults such as imbalances or misalignments, identify wear processes early and make optimal use of the lifespan of components.

  • Vibrating troughs

    Vibrating troughs

    Conveyor technology is the focus here. Vibration measurement technology helps to detect both increased and insufficient levels of vibration. Special vibration monitoring systems are available for this, such as Type 663-WINDOW.

  • Turbines


    Turbines and generators have their application in the chemical, oil & gas or paper industries. Measurement of housing vibration is a typical process and a sound measure in status monitoring that is indispensable for the system operator.

  • Pumps


    Pumps are indispensable for conveying liquid or solid media, making them a permanent feature of any industry. Vibration monitoring is the means of helping the system operator to achieve functional status monitoring.
