Measurement and Monitoring Devices from Schleicher Electronic

Schleicher Electronic Measurement and Monitoring Devices

Measurement and monitoring relays for high system availability.

A high level of equipment availability plays a crucial role in efficiency. All machine facilities should be fitted with rapid-response measuring and monitoring devices that continuously review and evaluate all electrical and physical states. This facilitates a quick and accurate response in the event of an error, for example proactive switch-off of the affected part of the system before the damage spreads to other unit components.

The Schleicher range of measurement and monitoring relays includes devices for all potential configurations.

Current and voltage monitors

  • Detection of low or excess voltages and currents by comparison with a preset threshold value
