Barksdale's L1X, T1X & T2X Series Temperature Switches provide unmatched performance, quality & reliability in a mechanical thermostat - a safe solution for hazardous locations. The Barksdale single set point L1X & T1X and  the Barksdale dual set point T2X, can switch, measure & control temperatures from 50° to 650°F (-45° to 343°C), and meets Class 1, Div. 1 & 2 hazardous location requirements. The optional adjustable differential provides precise control. These Barksdale switches can be mounted locally for control directly at the source or remotely up to 25 feet. The Barksdale L1X, T1X & T2X Series are electrically rated for 10 amps @ 125/250 VAC & 3 amps @ 480 VAC. Standard 3 & 6 pin terminal strips simplify installation. The Barksdale L1X, T1X & T2X Series are rated NEMA 4, 7 & 9 and incorporate stainless steel temperature sensors to handle a wide range of media. Optional thermowells allow the sensor to work in pressurized vessels to 5000 psi. The Barksdale L1X, T1X & T2X Series are UL listed & CSA approved & ATEX Certified for hazardous zones within the European Community.
