Key Benefits and Advantages
Elimination of Contamination Risk: The primary advantage of the fluidless design is the absolute removal of leakage risk. In traditional hygienic sensors, a diaphragm rupture could release fill-fluids into the food or drug batch, leading to costly waste and safety recalls. The EJAC60E uses a dry sensing mechanism, making it the safest choice for high-purity processing.
Advanced Duplex Stainless Steel Sensor: Yokogawa utilizes Duplex Stainless Steel (SST329J4L) as the standard sensor material. This material breakthrough provides the high corrosion resistance of 316L SST combined with the high structural tension of 630 SST. This dual-property metal ensures the sensor can withstand high-pressure spikes and frequent CIP/SIP cleaning cycles without fatigue.
Intelligent EJA-E Functionality: Despite its unique mechanical sensor, the EJAC60E maintains all the smart features of the EJA-E series. This includes a clear LCD display for local monitoring, simple range setting, and robust digital communication for remote diagnostics and process management.
Hygienic Adapter System: The transmitter is designed with a specialized adapter system that ensures a flush, crevice-free connection to the process. This prevents the accumulation of bacteria or product residue, meeting the stringent sanitary requirements of global food and drug regulatory bodies.
Reduced Maintenance and Downtime: Because there is no fill-fluid to expand or contract with temperature changes, the EJAC60E is exceptionally stable during temperature-cycling events (such as switching from process temperature to steam cleaning). This stability reduces the need for frequent zero-adjustments and increases overall process uptime.

Field of Application
The EJAC60E is the premier choice for hygienic pressure monitoring where the risk of oil contamination must be zero.
Primary Industries and Uses:
-
Food and Beverage: Monitoring pressure in milk pasteurizers, yogurt fermentation tanks, and brewery vessels.
-
Pharmaceuticals: Tracking pressure in sterile reactors, filtration units, and high-purity water systems.
-
Cosmetics: Managing the production of creams and lotions where oil-fill contamination would ruin the product consistency.
-
Dairies: Pressure measurement in high-viscosity liquid lines that require frequent Steam-In-Place (SIP) cycles.
-
Bio-Technology: Monitoring pressure in sensitive bioreactors where the introduction of foreign oils would kill delicate cell cultures.
