EC28 變送器
適用于有毒氣體、氧氣和氫氣的防爆區(qū)域
無論需要監(jiān)測有毒氣體、氧氣還是氫氣，EC28變送器與GfG可靠的控制器結(jié)合使用，都是安全且具成本效益的理想解決方案。該變送器獲得了ATEX認(rèn)證，即使在潛在爆炸性環(huán)境中也保證安全使用。
功能安全
EC28硬件符合歐洲功能安全標(biāo)準(zhǔn)DIN EN 61508-2: 2011，適用于多種氣體。在單通道（1oo1）或冗余（1oo2）配置下，其SI等級（最高可達(dá)SIL3）取決于氣體類型和傳感器。
通信與服務(wù)
EC28通過4-20 mA信號進(jìn)行通信。采用智能傳感器技術(shù)，可快速便捷地更換傳感器，并可選配RC2遠(yuǎn)程控制器，實(shí)現(xiàn)單人校準(zhǔn)和調(diào)整。
RC2遠(yuǎn)程控制器（可選）
氨氣和氫氣等氣體比空氣輕，相關(guān)變送器往往安裝在靠近天花板的位置。為了便于維護(hù)和檢修，可配備永久性安裝電纜，與RC2遠(yuǎn)程控制器相連，讓您隨時(shí)在地面操作變送器，大大簡化檢測
EC28 Transmitter
For Toxic Gases, O2 and H2 in Ex Zones
Whenever toxic gases, oxygen or hydrogen need to be monitored, the EC28 transmitter combined with one of GfG‘s reliable controllers is a perfect, cost-effective solution. This ATEX-certified transmitter guarantees safe use, even in potentially explosive atmospheres.
Functional Safety
The EC28's hardware complies with the European Functional Safety Standard DIN EN 61508-2: 2011 for many gases. The SI levels (up to SIL3) in single channel (1oo1) or redundant (1oo2) use depend on the gas type and the sensor.
Communication and Service
The EC28's communication works on a 4-20 mA signal basis. Smart Sensor technology allows for quick and easy sensor replacements and the RC2 remote control can be used to make adjustments (one-person calibration).
RC2 remote control (optional)
Gases like ammonia and hydrogen are lighter than air. Transmitters to detect them are therefore installed near the ceiling. To facilitate service and maintenance work, they can be equipped with a permanently installed cable which can be connected to an RC2 remote control. This lets you access the transmitter from ground-level at all times, making inspection, calibration or maintenance work significantly easier.
Reliable Measurement & Minimal Operating Costs
The sensor and built-in temperature compensation guarantee high measuring accuracy. The long sensor service life and low maintenance requirements ensure minimal operating costs.
