Series T1X, T2X and L1X

Barksdale_Temp Switch_T1X Description
Barksdale's L1X, T1X and T2X Series Temperature Switches provide unmatched performance, quality and reliability in a mechanical thermostat - a safe solution for hazardous locations. The single set point L1X & T1X and dual set point T2X, can switch, measure and 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 switches can be mounted locally for control directly at the source or remotely up to 25 feet. The L1X, T1X and T2X Series are electrically rated for 10 amps @ 125/250 VAC and 3 amps @ 480 VAC. Standard 3 & 6 pin terminal strips simplify installation. The L1X, T1X and 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 L1X, T1X and T2X Series are UL listed and CSA approved and ATEX Certified for hazardous zones within the European Community.
