Barksdale's TS2000 offers the accuracy of an electronic temperature switch combined with a temperature transducer in a single, economical package. Our TS2000 is available in two different configurations: as a dual temperature switch or as a single switch with integrated 4-20 mA analog output. Setpoints and deadband are easily adjusted by using the keypad and the user-friendly menu. Analog transducer outputs are scalable from 25% to 100% of the full adjustable range. A 10-bit microprocessor provides built-in self-diagnostics and allows for switch time delays and cycling up to 100 times per second. For applications requiring precise temperature monitoring and control at an affordable price, the TS2000 is the ideal solution.

  • High accuracy with fully adjustable deadband
  • Optional 4-20 mA analog output
  • Built-In digital display readout
  • Fully configurable via keypad
