Electronic temperature switches

December 2010 Temperature Measurement

The Kobold range of electronic temperature switches are suited to applications where temperature must be monitored with a high degree of repeat accuracy such as pumps, compressors, mechanical and plant engineering. The TDD series integrates the latest solid state sensing technology into a versatile, simple to operate package. Programming features include set-point, reset point, window mode, dampening, switch logic and user selectable lockout code.

The Pt-100 RTD sensing system and solid state transistor switch ensures a long cycle life with virtually no calibration drift. Switching ranges are -20 to 120°C with an accuracy of ±0,5°C for temperatures from 0–70°C and ±3°C for 70–110°C. In addition to the switch output, the TDD has a 3-digit LED display for local indication of temperature and programming of switch points and housed in stainless steel for corrosion resistance.
