Product Description

Henghe eja**0a differential pressure transmitter adopts single crystal silicon resonant sensor technology. Monocrystalline silicon is a very ideal material because it has no hysteresis for the change of pressure or temperature. The single crystal silicon resonant sensor reduces the influence of over-voltage, temperature change and static pressure to a low level, thus providing            Specifications of eja**0a            Eja**0a differential pressure transmitter            L capsule, m capsule, H capsule, V capsule            Measurement range - *0 ~ *0KPA            (- *0 ~ *0inh2o) - **0 ~ **0KPA            (***0~**0inH2O) ***0~**0kPa            (****0~***0inH2O) *0.5~*4MPa            (**0~***0psi)            Measuring range: 0.5 ~ *0KPA            (2~*0inH2O) 1~**0kPa            (4~**0inH2O) 5~**0kPa            (*0~***0inH2O) 0.*4~*4MPa            (*0~***0psi)            Accuracy ± 0.**5% ± 0.**5% ± 0.**5% ± 0.**5%            Degree of protection IP*7, NEMA 4x, and JIS c***0 immersion proof            Explosion proof specification FM, CENELEC ATEX, CSA, IECEx            Output signal: 4 ~ *0mA DC, foundation fieldbus or PROFIBUS PA two-wire digital communication            Power supply: brain and Hart: *0.5 ~ *2V DC (intrinsically safe: *0.5 ~ *0V DC)            Fieldbus: 9 ~ *2V DC (intrinsic safety entity mode 9 ~ *4V DC, intrinsic safety FISCO mode 9 ~ *7.5V DC)            Ambient temperature: - ****5 ℃ (- *****5 ℉) (ordinary type)            *****0 ℃ (- *****6 ℃) (built-in indicator)            Process temperature: - *0 ~ **0 ℃ (- *0 ~ **8 ℉) (common type)            Large working pressure: *6MPa (***0psi)            L capsule (special material) 3.5Mpa (**0PSI)            Installation of *-inch pipe            Wetted part material: capsule SUS**6L (diaphragm: Hastelloy C***6),            Hastelloy C***6, tantalum, Monel            Cover flange SUS**6, Hastelloy C***6, Monel            Shell: aluminum alloy or SUS**6 stainless steel (optional)            Eja**0a type selection table            Basic specification code: eja**0a-dms5a**2nn            Item 1: output signal - D ***0mA DC / brain protocol digital communication            -E ***0mA DC / HART protocol digital communication            -F FF Fieldbus Communication            Item 2: measurement range (capsule): l 0.***0kpa            M ****0KPa            H ****0KPa            V 0.****4MPa            Item 3: wetted part material: s JIS SCS*4A JIS SUS**6L JIS SUS**6            H JIS SCS*4A Hastelloy C***6 JIS SUS**6            M JIS SCS*4A Monel JIS SUS**6            T JIS SCS*4A tantalum JIS SUS**6            A Hastelloy C***6 Hastelloy C***6 Hastelloy C***6            D Hastelloy C***6 tantalum Hastelloy C***6            B Monel Monel            Item 4: process interface 0 no process connector (RC1 / 4 internal thread on the chamber flange)            1.
