Product details
summary
ECA430APressure transmitters are used to measure the pressure of gases, liquids, and vapors, and then convert it into a 4-20mADC current signal output. The ECA430A can also communicate with the HART275 handheld device for setting, monitoring, and other purposes.
Functional specifications
output
2-wire system, 4-20mA DC output, digital communication, programmable linear or square root output mode, HART protocol loaded on 4-20mA DC signal.
supply voltage
10.5~42V DC (working state)
(10.5-30V DC intrinsic safety type)
16.4~42V DC (digital communication)
(16.4~30V DC intrinsic safety type)
9.0-32VDC (FF fieldbus communication)
load
0-1335 Ω working state
250-600 Ω digital communication
HART
Communication Distance
Using multi-core twisted pair cables, the maximum communication distance can reach 1.5km, and the communication distance varies depending on the cable type.
Damping time constant
The sum of damping time constants for amplifier components and membrane enclosures. The damping time constant of amplifier components can be adjusted within the range of 0.2 to 64 seconds
ambient temperature
-40～85℃(-40～185°F)
-30-80 ℃ (-22-176 ° F) [with LCD meter head]
Liquid contact temperature
-40～120℃(-40～248°F)
Performance specifications
Reference accuracy for range adjustment (including linearity, hysteresis, and repeatability from zero) ± 0.1%
