Controllers are immersion type devices for limiting or
regulating the temperature of liquids in boilers, storage tanks, and
other applications where temperature control is required.
• Totally enclosed Micro Switch™ snap-acting switches operate on
temperature rise to setpoint.
• Visible control point scale and external adjustment screw permit
easy setting.
• Horizontal or vertical insertion of the sensing element.
• Direct or well immersion of the sensing element.
• Models available for strap-on mounting.
• Remote bulb model may be used to sense air temperature in ducts
and in outside air sensing applications.
• Select models have wells.
• UL limit rated device.
