Yokogawa EJA120E Differential Pressure Transmitter
One -way overvoltage characteristics are excellent
No bracket, install it directly
Used in routine, no three valve groups need
The impact of static pressure is ignored
EJA-E high-performance differential pressure variable transmitter uses single crystal silicon resonant sensor technology, which is suitable for measuring flow, liquid level, density and pressure of liquid, gas or steam
EJA-E converts differential pressure to 4 ～ 20mA DC current signal output. It can measure, display or monitor remote monitoring static pressure, and has functions such as rapid response, remote settings, and self -diagnosis.
The EJA-E series products provide bravery protocols such as Brain, Hart/Hart (1 ~ 5VDC), FF live bus and Profibus PA, etc. The standard configuration has passed SIL 2 security certification.
Performance specifications:
Unless it is special, it usually adjusts the range of schedules at zero point, linear output, and some material code "s", and the filling fluid is silicon oil. For the FF live bus and Profibus PA communication protocol, the scope of correction is replaced by the range of the following specifications.
Specifications consistency:
The EJA-E series ensures the consistency of at least ± 3 σ.
Reference accuracy of adjustment range:
(Including the linear, lag, and repetitiveness based on end -based)
Signal curve (the output signal code is D, J & Q)
You can set the 10 -segment signal curve table to sign 4 to 20mA output for testing
The boiler boiler bag, cone tank liquid level, etc.
SIL certification
The EJA-E series variables meet the following standards:
IEC 61508: 2000; part 1 ~ part 7
The functional safety of the electronic/electronics/programmable electronic -related system;
A single station meets SIL2 security requirements, and redundant use meets SIL3 security requirements.
Except for FF live bus, Profibus PA and HART low -power consumption types.
