Yokogawa Differential Pressure Transmitters
Yokogawa EJA210 Differential Pressure Transmitters
The high performance flange mounted differential pressure transmitter models EJA210A and 220A can
be used to measure levels of densities of solidifying or precipitating liquids. Both output a 4 to 20 mA DC
signal corresponding to the measured differential pressure. Models EJA210A and 220A also feature
remote setup and monitoring through communications with the BRAIN™ terminal and CENTUM CS™ or
XL™ or HART® 275 host.
General technical performance and parameters :
Output signal: 4-20ma. DC two-wire system (simulation)
Two - wire 4-20mA dc signal superimposed digital signal, by the user selection of linear or square output.(smart)
Power supply: 12 ~ 45v. DC (see the load characteristic figure for details)
Quantum ratio: 10:1 or 100 to 1
Power supply impact: <0.005% output range /V
Load effect: when the power supply is stable, there is no load effect.
Measurement accuracy: + / -0.1%, + / -0.2% of the adjusted range (standard accuracy: + / -0.2%, please specify
when ordering other precision.)
Zeni: usually adjustable between 0.1 and 16 seconds.
Start time: <2 seconds, no need to warm up
Working environment: the environment temperature - 29 ~ 93 ℃ (analog amplifier)
- 29 ~ 75 ℃ (digital/intelligent amplifier)
- 29 ~ 65 ℃ (with display header)
Ambient humidity 0 ~ 95%
Protection features: protection capability IP65
Explosion-proof type: flameproof type Exd II bt4-6
Benan Exia II CT5
Static pressure effect: zero error: + / - 0.5%zui large range limit, adjusted for 32MPa under pipeline pressure
by zero setting.
Effect of electromagnetic radiation: 0.05%zui large range value, receiving radiation frequency of 27 ~ 500MHz,
with a field strength of 3V/m.
Indicator (%) : liquid crystal display accuracy + / - 0.2%
Vibration effect: at 200Hz vibration in any direction, plus or minus 0.05%/g.
Mounting position: the diaphragm is not vertically installed, which may cause a zero error of less than 0.24kpa,
but can be corrected by setting the zero.
Weight: 3.9kg (excluding attachments)
