產(chǎn)品說明
EJA130A高靜壓差壓變送器
EJA130A型高性能的差壓變送器可用于測量液體、氣體或蒸汽的流量，以及液位、密度和壓力。
產(chǎn)品信息
EJA130A型高性能的差壓變送器可用于測量液體、氣體或蒸汽的流量，以及液位、密度和壓力，然后將其轉(zhuǎn)換成4~20mA DC的電流信號輸出。
EJA系列支持BRAIN、HART和FOUNDATION™現(xiàn)場總線或PROFIBUS PA通信協(xié)議。
特性
-
的性能和穩(wěn)定性
EJA系列采用單晶硅諧振式傳感器技術(shù)。單晶硅對于壓力或溫度的變化不存在滯后現(xiàn)象，是非常理想的材料。單晶硅諧振式傳感器將過壓、溫度變化和靜壓影響降為zui低，從而提供的長期穩(wěn)定性。
-
小型輕量設(shè)計(jì)
由于采用ASIC放大器設(shè)計(jì)使包裝變小，以及膜盒構(gòu)造和法蘭的小型化，這款機(jī)型的重量降到了原有機(jī)型的一半。ASIC設(shè)計(jì)不僅減少了零件數(shù)量，而且提高了放大器的可靠性。
-
現(xiàn)場總線通信能力
現(xiàn)場總線是雙向數(shù)字通信系統(tǒng)，是配置儀表控制系統(tǒng)的革新技術(shù)，同時(shí)也是前景很好的更新?lián)Q代產(chǎn)品，用于替換現(xiàn)在現(xiàn)場儀表中廣泛使用的標(biāo)準(zhǔn)4~20mA模擬通信。
EJA系列提供兩種現(xiàn)場總線模式，F(xiàn)OUNDATION™現(xiàn)場總線低壓模式和PROFIBUS PA設(shè)備，以實(shí)現(xiàn)橫河電機(jī)和其他供應(yīng)商的協(xié)同工作。軟件方面，EJA系列采用兩個AI功能塊計(jì)算差壓和靜壓，從而實(shí)現(xiàn)靈活的儀表配置。

Optional codes
/□ Optional specification
The ‘6’ marks indicate the most typical selection for each specification. Example: EJA130A-DMS-92NA/□
The ‘#’marks indicate the construction materials conform to NACE material recommendations per MR01-75. For the use of SUS316 material, there may be certain limitations for pressure and temperature. Please refer to NACE standards for details.
*1: Indicates material of cover flange. Material of process connector is SCS14A(SUS316 equivalent).
*2: Diaphragm material is Hastelloy C-276 or ASTM N10276. Other capsule wetted parts materials are SUSF316L, SUS316L or ASTM grade 316L.
*3: If necessary, specify Mounting bracket code C, D or K.
*4: If necessary, specify Mounting bracket code A, B or J.
*5: Lower limit of ambient and process temperature is —15°C.
*6: Not applicable for Output signal code F and G.
*7: Users must consider the characteristics of selected wetted parts material and the influence of process fluids. The use of inappropriate materials can result in the leakage of corrosive process fluids and cause injury to personnel and/or damage to plant facilities. It is also possible that the diaphragm itself can be damaged and that material from the broken diaphragm and the fill fluid can contaminate the user's process fluids.
Be very careful with highly corrosive process fluids such as hydrochloric acid, sulfuric acid, hydrogen sulfide, sodium hypochlorite, and high-temperature steam (150°C [302°F] or above). Contact Yokogawa for detailed information of the wetted parts material.
*8: SUS316 or ASTM grade 316.
