Lineman Power Monitors

WARRENDER LINEMAN
Power monitors are solid-state electronic monitoring and control units, specially designed to protect valuable pump equipment against irregular operating conditions like dry running, cavitation and impeller jamming. If such an event occurs, the monitor will sound an alarm and automatically shut down your system, preventing chemical spillage or damage to costly equipment.

LINEMAN power monitors use the motor as a sensor, observing for specific changes in electrical current that indicate an impending hazardous condition. By eliminating the need for additional mechanisms or sensors to be installed within the driven process, LINEMAN monitors can reduce the risks of contamination and leakage caused by breaches in the system.

In addition to detecting and preventing equipment damage, these state of the art control units provide accurate measurement of power consumption and/or motor output.

The LINEMAN LM-5, LM-6 and LM-7 units can also be interfaced with process control applications to provide feedback on changes in operating conditions such as fluid viscosity or system pressure, for reliable automatic process control.

All LINEMAN power monitors are compact and lightweight, and can be mounted to standard 35mm DIN rails as specified by DIN 46277.

LM-3 Model

The LINEMAN LM-3 power monitor is a single-function unit, intended for applications that demand safeguard against a specific operational hazard. Ideal for protection of centrifugal pumps against dry-running, the LM-3 is a cost-effective monitoring solution for machine builders and OEMs. For more advanced multi function load monitoring, see the LM-5, LM-6 and LM-7. 

• Lightweight, small footprint design easily fits into most any electrical power cabinet. 
• Mounts onto a standard 35mm DIN rail (DIN 46277). 
• Easy installation and set up within minutes - no sensors to install. Alarm sets at the push of one key. 
• Digital display provides clear readout at all times. 
• Provides consistent sensitivity across the complete load range of the pump motor. 
• Single trip switch can be set to sound an alarm and stop the pump automatically in event of either over- or under-load condition 
• Operates on 50 or 60Hz AC. 
• CE, cUL and UL approved (up to 600 V).
