The TDA series digital temperature sensor incorporates the latest sensing technology into a very versatile, simple to operate package. Output span, dampening and lockout code are programmable from a keypad on the controller. The heart of the sensor is a semiconductor sensing element which sends a digital temperature signal to the processor in 0.5°C increments. The processor displays temperature and provides a 4-20 mA output proportional to temperature. The digital sensor ensures a long life with virtually no calibration drift. These features along with a robust stainless steel housing makes the TDA ideal for OEM or tough industrial applications. The TDA 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.
