Key Benefits and Advantages
Exceptional Reliability and Precision: The EJXC80A and EJAC80E systems inherit the legendary accuracy of the DPharp series. They provide a stable and high-accuracy output even when the transmitter is located at a distance from the process, ensuring consistent control in complex industrial loops.
Optimized for High-Temperature and High-Vacuum: These systems are specifically designed to withstand extreme environments. They are capable of operating in high-vacuum conditions down to 0.013 kPa abs, making them ideal for distillation columns and vacuum reactors that require precise pressure monitoring without compromising the seal.
Advanced Diaphragm Protection: The diaphragm seals protect the internal transmitter components from aggressive process fluids, high-viscosity liquids that might clog the sensor, and extreme temperatures. This isolation extends the service life of the instrumentation and reduces the frequency of maintenance.
Enhanced Response Performance: Despite the use of capillary fill fluids, the EJXC80A/EJAC80E systems are optimized for speed. They deliver a fast response time of 200 ms, providing the necessary agility for control systems to manage dynamic process changes in real-time.
Versatile System Configuration: Available in both differential and gauge pressure versions, these systems offer a wide variety of seal sizes, flange ratings, and fill fluids. This versatility allows the system to be tailored to specific chemical compatibilities and environmental requirements.
Minimized Ambient Temperature Effects: Yokogawa’s proprietary design and manufacturing process for diaphragm seals minimize the errors caused by ambient temperature fluctuations along the capillaries, ensuring that the measurement remains accurate regardless of environmental changes.
