详细描述Detailed description

EE300EX是一款专为应用在危险场合设计的本安型防爆温湿度变送器。满足欧洲(ATEX)、国际(IECEx)和美国/加拿大(FM)规范对现场工作仪表的本案防爆要求。因此EE300EX可以在危险的粉尘区或可燃性气体环境中工作。

壳体本体与底座两部分拆装理念促进了测量部分的简便安装和快速更换,避免了耗时重新接线。这意味着EE300EX可以直接放在爆炸危险环境中0/20区使用。

易于清洁、优雅的不锈钢外壳是使用在医药和化工等行业的一个重要特征。经过多年实践经验证明,在富有挑战性的工业应用中,E+E湿度传感技术能确保可靠的测量性和长期稳定性。

墙面安装型、10m分体测量探头型或者可选带显示都使EE300EX为用户提供了更加多的功能选择。EE300EX的设计采用两线制技术,可以通过任何本安型电源或者齐纳安全栅来供电。测量值通过2个4…20mA模拟信号输出,用户可以通过简单的操作对变送器进行输出组态。

除了用于相对湿度和温度的测量,EE300EX变送器还提供了依据标准公式计算的其它相关测量值,如露点温度[Td],湿球温度 [Tw],绝对湿度 [dv]等等…

油中水份的测量:

如同可以测量空气中的湿度,EE300EX也能够用来测量油中水份。油中水分含量可以选择绝对含水量[ppm]或相对水活性[aw]的方式进行输出。

油中水份测量的典型应用有油的净化系统,石油平台上进行润滑油及齿轮油的在线监测。

特点/优势:

  • 可用于气体和粉尘爆炸危险区域
  • 可以直接安装在0 / 20区
  • 具有湿度计算输出功能
  • 即使在180°C的高温下也能保持高精度
  • 最大可承受300bar的压力
  • 型号有墙面安装型和分体探头型可选
  • 可测量油中水份

典型应用:

  • 化工行业
  • 制药行业
  • 防爆危险区域储藏室
  • 发电站
  • 粮食加工厂
  • 石油平台

 

The EE300Ex intrinsically safe transmitter measures reliably relative humidity (RH) and temperature (T) in explosion hazard areas. It complies with the classifications for Europe (ATEX), International (IECEx), USA / Canada (FM) and China (NEPSI) for flammable gas and dust applications. The EE300Ex it is also certified for gas applications according Korean (KC) and Japan (TIIS) certifications.

The entire device can be placed in the explosion endangered area. The remote sensing probe allows for classification up to T6.

Measurement performance

The well proven E+E humidity sensors and competence in calibration allow for highly accurate and long term stable measurement over the full range 0…100 % RH and -40…180 °C (-40...356 °F), with pressure rating up to 300 bar (4351 psi).

Besides the RH and T measurement, the EE300Ex calculates all humidity related parameters such as dew point temperature (Td), frost point temperature (Tf), absolute humidity (dv) or mixing ratio (r).

Moisture in oil measurement

The EE300Ex with ATEX, IECEx, NEPSI and KC approval is suitable also for measuring water content (x) in ppm and water activity (aw) in isolation, lubrication and hydraulic oils. Typical applications include oil purifiers and online monitoring of lubrication and hydraulic oils.

Supply and outputs

The device can be powered by any intrinsically safe supply unit or via

Zener barriers. The measured or calculated data is available on two 4…20 mA, 2-wire outputs and on the LCD display.

Robust, functional design

The stainless steel enclosure and sensing probe are suitable for harsh environment in challenging industrial applications.

The EE300Ex design facilitates the installation as well as the replacement of the measuring section (electronics and

probe) without time consuming wiring.

Protective sensor coating

The E+E proprietary sensor coating is a protective layer applied to the active surface and leads of the sensing elements.

The coating substantially extends the lifetime and the measurement performance of the E+E sensor in corrosive

environment (salts, off-shore applications). Additionally, it improves the long term stability in dusty or dirty applications by preventing stray impedances caused by deposits on the active sensor surface.
