YOKOGAWA EJA110E-FMS5C-917DB/KS26/D3/M01 4 to 20 mA liquid gas steam Pressure Transmitter

The high performance differential pressure transmitter EJA110E features single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam flow as well as liquid level, density and pressure. EJA110E outputs a 4 to 20 mA DC signal corresponding to the measured differential pressure. Its accurate and stable sensor can also measure the static pressure which can be shown on the integral indicator or remotely monitored via BRAIN or HART communications. Other key features include quick response, remote set-up using communications and self-diagnostics. FOUNDATION Fieldbus, PROFIBUS PA and 1 to 5 V DC with HART (Low Power) protocol types are also available. All EJA-E series models in their standard configuration, with the exception of the Fieldbus, PROFIBUS and Low Power types, are certified as complying with SIL 2 for safety requirement.Total Probable Error (M capsule) ±0.20% of Span @1:1 to 5:1 Rangedown Total probable error, known as a measure of the total performance of the transmitters under the condition of fixed line presurre. Total Probable Error = ± E12 + E22 + E32 E1: Reference Accuracy of Calibrated Span E2: Ambient Temperature Effects per 28°C change E3: Static Span Effects per 6.9 MPa change ? Total Accuracy (M capsule) ±0.17% of Span @1:1 Rangedown ±0.33% of Span @ 5:1 Rangedown Total accuracy is a comprehensive measure of transmitter total performance, covering all major factors in actual installation, that cause errors in measurement. As a standard measure, YOKOGAWA uses this to evaluate transmitter performance. Total Accuracy = ± E12 + E22 + (E3 + E4)2 + E52 E1: Reference Accuracy of Calibrated Span E2: Ambient Temperature Effects per 28°C change E3: Static Span Effects per 6.9 MPa change E4: Static Zero Effects per 6.9 MPa change E5: Overpressure Effects upto overpressure 16MPa Not only a day-to-day changes in temperature can affect the measurement and lead to unnoticed errors; fluctuaion of line pressure, incorrect operation of three/five valve manifold leading to over-pressure events, and other phenomena can have the similar result. Total Accuracy factors in such changes and errors and provides much comprehensive and practical determination of how a transmitter will perform under actual plant operation.Overpressure Effects Overpressure condition: up to maximum working pressure M, H and V capsules, except for gold-plated diaphragm. ±0.03% of URL Stability (All normal operating condition, including overpressure effects) M, H and V capsules ±0.1% of URL per 10 years F capsule ±0.2% of URL per one year Power Supply Effects(Output signal code D and J) ±0.005 % per Volt (from 21.6 to 32 V DC, 350Ω) Vibration Effects Amplifier housing code 1 and 3: Less than 0.1% of URL when tested per the requirements of IEC60770-1 field or pipeline with high vibration level (10-60 Hz, 0.21 mm displacement/60-2000 Hz 3 g) Amplifier housing code 2: Less than ±0.1% of URL when tested per the requirements of IEC60770-1 field with general application or pipeline with low vibration level (10-60 Hz 0.15mm displacement /60-500 Hz 2g) Mounting Position Effects Rotation in diaphragm plane has no effect. Tilting up to 90 degree will cause zero shift up to 0.4 kPa (1.6 inH2O) which can be corrected by the zero adjustment. Response Time (Differential pressure) 90 ms for Wetted Parts material code S and L, except for Measurement span code F. 150 ms for Wetted Parts Material Code H, M, T, A, B, D and W or Measurement span code F. When amplifier damping is set to zero and including dead time of 45 ms (nominal)Static Pressure Signal Range and Accuracy (For monitoring via communication or on indicator. Includes terminal-based linearity, hysteresis, and repeatability) Range Upper Range Value and Lower Range Value of the static pressure can be set in the range between 0 and Maximum Working Pressure(MWP). The upper range value must be greater than the lower range value. Minimum setting span is 0.5 MPa(73 psi). Measuring either the pressure of high pressure side or low pressure side is user-selectable. Accuracy Absolute Pressure 1 MPa or higher: ±0.5% of span Less than 1 MPa: ±0.5%×(1 MPa/span) of span Gauge Pressure Reference Gauge pressure reference is 1013 hPa (1 atm) Note: Gauge pressure variable is based on the above fixed reference and thus subject to be affected by the change of atomospheric pressure. □ FUNCTIONAL SPECIFICATIONS Output For 4 to 20 mA HART / BRAIN (Output signal code D and J) Two wire 4 to 20 mA DC output with digital communications, linear or square root programmable.

Note: For BRAIN protocol type, when amplifier software damping is set to less than 0.5 s, communication may occasionally be unavailble during the operation, especially while output changes dynamically. The default setting of damping ensures stable communication.
