Load Sensors
Load Sensors
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 overcur-
rent and undercurrent or either overcurrent or undercurrent 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.
