SymCom's load sensors are designed to be adaptable to many different applications. They utilize a CT (current transformer) inside the unit to read the current of the equipment being monitored. The Model LSR-0 is a self-powered unit used as a proof relay. The LSRX and LSRX-C units are also self-powered proof relays with either 0.25" fast-on connectors (LSRX) or depluggable connectors (LSRX-C) for use in OEM equipment. The LSR-24, 115 and 230 load sensors require external power and are ideally used to help determine feed rates, tool wear, loss of prime on pumps, mixer viscosity and all types of overload and underload conditions. LSRU load sensors come in many different configurations, such as overcurrent and undercurrent or either overcurrent or under-current with variable trip, restart or extended restart delay settings. All LSRU models require 115VAC external power source, except for the LSRU-24-AL-2 and LSRU-24-AL-3, which require 24VAC.
