The Trerice Series L84000 Electric Contact
Controller is designed for applications that
require the opening and closing of electric
solenoid valves, heaters, and other electrical
devices. It is a rugged and versatile controller,
capable of producing “On/Off” control over a
wide range of temperatures from -100°F to
700°F. This controller includes a setting
adjustment knob and one or more SPDT
electric contact switches.
For applications where the process media may be
corrosive or contained under pressure, the use of a
thermowell is required to prevent damage to the
controller and facilitate its removal from the process.
