VARIMETER measuring and monitoring relays for voltage, current, power and frequency

DOLD's VARIMETER range covers measuring and monitoring relays for applications where electrical safety comes first. The relays watch values including current, voltage, phase failure, active power, frequency, insulation faults and standstill, and they signal early when a critical limit is crossed. This protects even complex systems and keeps production running smoothly. LEDs on the front of each device show its current status at a glance.

The programme includes monofunctional relays for a single measured variable as well as multifunctional, universally applicable units. Single-function devices keep costs low, while multifunction relays offer more flexibility. Dedicated versions exist for self-generating systems and for monitoring physical quantities. Typical fields of use are air-conditioning and ventilation, traffic engineering such as signal monitoring, building services and plant automation.
