Stops damage on machines
Load monitor for industrial motors
The load monitors of the DOLD varimeter series are available with relay or with analogue output. Both units measure the effective power of electrical motors with variable motor load.
While the load monitor BH 9097 has 2 relay outputs and 2 separate adjustable tripping values, the BH 9098 comes with a load depending, galvanic separated analogue output, giving 0-20mA and 0-10V or 4-20mA
The varimeters monitor single or 3-phase load and are available for ratings from 60 W up to 48 kW. Start up delay and operating delay are adjustable with potentiometers. Indication is provided with LEDs.
Applications for BH 9097 are monitoring of machines to detect wearing of tools, heavy movement, blocking and broken belts. The BH 9098 is used in controls for industrial drives and process control.
