The TDD series digital temperature switch integrates the latest solid state sensing technology into a very versatile, simple to operate package. Programming features include setpoint, reset point, window mode, dampening, switch logic and user selectable lockout code. The digital semiconductor sensing system and solid state transistor switch ensure an exceptionally long cycle life with virtually no calibration drift. These features along with the compact, robust stainless steel package make the TDD an ideal choice for OEM or industrial applications. The TDD is available with the controller mounted directly onto the sensing probe or separated for mounting the probe remotely from the controller. Various probe lengths are available. The remote probe version has a smooth shank (no fitting) allowing the user to adjust the probe insertion depth by installing with a compression fitting sold as an accessory item.
