Product details

EJA120A Micro Differential Pressure TransmitterDetailed information:

The EJA120A micro differential pressure transmitter is used to measure the liquid, gas, and vapor levels, densities, and pressures, and then convert them into 4-20mADC current signals for output.

EJA120A is also availableProduced by Jiangsu Wanxun Instrument Co., LtdHART handheld devices communicate with each other for settings, monitoring, etc.

2、 Functional specifications

Output: Two wire system, 4-20mADC output, digital communication, programmable linear or square root output mode, HART protocol loaded on 4-20mADC signal.

supply voltage

10.5-42VDC (working state)

10.5-30VDC (intrinsic safety type)

16.4-42VDC (digital communication)

16.4-30VDC (intrinsic safety type)

Load (when output signal codes are E and S): 0-1335 Ω working state

Damping time constant: the sum of the damping time constants of the amplifier component and the diaphragm box. The damping time constant of the amplifier components can be adjusted within the range of 0.2 to 2 seconds.

Work pressure: -50~50KPa (-7.25~7.25psi)

Environmental temperature: -20-80 ℃ (-13-176 ℃)⁰F）

Liquid contact temperature: -25-80 ℃ (-13-176 ℃)⁰F）

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.

3、 Performance specifications

Reference accuracy for range adjustment: including linearity, hysteresis, and repeatability from zero) ± 0.2% ± 0.1% (high accuracy)

Example: EJA120A-EES5A-92NN
Note 1: Refers to the material of the chamber flange and process joint
Note 2: The material of the diaphragm is Hastelloy C-276, and the material of the remaining liquid receiving parts is SUS316L

Note 3: If necessary, select installation brackets with codes C and D
Note 4: If necessary, select installation brackets with codes A and B

Note 5: Not applicable to output signal codes F and G.

Note 6: Users must consider the characteristics of the liquid receiving part and the corrosiveness of the medium. Inappropriate materials may cause unexpected leakage of corrosive media, causing serious damage to human health and factory equipment Attention must be paid when selecting: if the medium has strong corrosion, such as hydrochloric acid、Sulfuric acid H2SSodium hypochlorite, etc150Please contact Yokogawa Instruments for high-temperature steam at or above ℃.
