EJA115E Low Flow Transmitter
The EJA-E series of transmitters is Yokogawa's most recent evolution of the DPharp family of pressure transmitters.
Released in 2012, it combines the ruggedness and success of the work-horse EJA-A series with the performance of the thoroughbred EJX-A series to deliver the type of product you have come to expect from Yokogawa.
The EJA115E is Differential Pressure Transmitter in the series optimized for low flow applications with the addition of an Integral Flow Orifice (IFO) assembly. The EJA115E is designed to measure accurately, transmit quickly, and do it reliably over time.
- Accurately: ±0.055% Square Root Output Accuracy
- Quickly: 90 ms Response Time
- Reliably: ±0.1% per 10 years Stability (DP)
The low flow transmitter EJA115E is a differential pressure transmitter (Secondary Element) assembled with an integral orifice (Primary Element). The EJA115E is engineered to provide excellent low flow measurement. It outputs an analog 4 to 20 mA DC signal corresponding to the measured flow. Its accurate and stable DPharp pressure sensor can also measure the static pressure. The static pressure can be displayed on the integral indicator or remotely monitored via digital communications. Other key features include quick response, remote set-up using communications, and self-diagnostics. Analog 4 to 20 mA DC with HART (5 or 7) or BRAIN protocol, all digital FOUNDATION Fieldbus or PROFIBUS PA, or 1 to 5 V DC with HART 7 (Low Power) protocols are available. All EJA-E series models in their standard configuration, except the FOUNDATION Fieldbus, PROFIBUS PA and 1 to 5 V DC types, are certified by TÜV as complying with SIL 2 for safety requirement.
