Yokogawa’s DPharp digital sensor offers twice the performance and stability of the competitor’s analog sensors. The DPharp uses the latest in IC Chip-style design and manufacturing technology. Analog sensors are based on older design technology. Although analog sensors are good, the modern DPharp sensor out performs them. A Yokogawa transmitter with DPharp digital sensor will give you the consistent, reliable, accurate measurement you need. Yokogawa’s transmitter has 40 self-diagnostic checks to ensure that everything is running smoothly within the transmitter. But, all transmitters on the market have a level self-diagnostic checks. However, Yokogawa has two that are not offered by competitors. First, the transmitter features a patented Back-check Technology that reverse checks all calculations in real-time. Second, the DPharp sensor is an active sensor. This means that the sensor is constantly supplying a signal even when the process has not changed. If the signal is lost from the sensor, the transmitter knows there is an issue. Competitor’s analog sensors are passive.
