Description

The EJX930A is a multivariable transmitter and is part of the EJX-A series. It is designed specifically for high static pressure applications features multi-sensing technology with a single-crystal silicon resonant sensor that outputs the measured differential pressure, static pressure and process temperature, which covers multiple protocols including HART, FOUNDATION fieldbus and RS485 Modbus.

• Utilizes DPHarp sensor technology

The EJX930A with DPharp digital sensor offers the performance needed to run your operations at peak performance. This ensures on-spec product, reduced waste, and improved yield, helping you increase profitability.

 Dynamic Compensation

All flow factors for mass flow calculation are dynamically compensated to an optimum value. The flow factors that are automatically compensated are: discharge coefficient, diameter of primary device, upstream internal pipe diameter, gas expansion factor, density, and viscosity.

Digital Performance

The DPharp sensor directly outputs a digital signal, eliminating the need for analog to digital conversion and improving performance.

Long-term Stability

When installed in the field, DP transmitters are subjected to continuous variations in pressure and temperature which will affect the accuracy. The performance may drift over time and is quantified using long term stability. There is unconditional guarantee of long-term stability under the complete range of operating conditions.

Standard Diagnostics

Standard

• 40 self-diagnostic checks to ensure that everything is running smoothly within the transmitter.
• The transmitter features a patented back-check technology that reverse checks all calculations in real-time.
• The DPHarp sensor is an active sensor, 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.

Advanced

Predictive impulse line blocking and heat tracing diagnostics anticipate whether troubleshooting is needed.

Local Indicator

Easy to read indicator provides all the information you need. The indicator can display any of the variables measured (DP, SP, External Temperature); alarm codes with short text; and a sweeping bar graph to give a graphical representation of the process. Fully programmable, the indicator is customizable for your needs.
