EE820

EE820是专为苛刻环境应用设计的一款高量程CO₂变送器。生产过程中特有的多点二氧化碳和温度校准步骤保证了变送器在整个温度工作范围测量的高精度。

  • EE820 CO₂ sensor for wall mounting

    EE820采用的是E+E单光源双光速红外线测量技术,可自动进行光源老化补充,并具有较高的抗污染能力,从而保证了产品出众的长期稳定性。

    配备的IP54防护等级的外壳和特殊的过滤器,使EE820可以应用在污染工况中,例如农业和畜牧业。在进行清洁操作前,使用M12接头可以方便地拆除变送器。

    FAQ

    Not at all. Do not temper in any way with the CO₂ sensing cell. Please see the operation manual of the specific E+E CO₂ measurement device.

    Please the section "Maintenance" in the operation manual.

    All E+E CO₂ measuring devices feature an auto-calibration function. For details please refer to "Principles of CO₂ measurement".

    Transmitter with "two-wire" technology receive the power from the process, and the signal is carried on return wire (closed current loop). With "three-wires" technology the power supply is separate from current output: 2 wires are the power supply and the third carries the signal.
