ENVENT分析仪介绍
MODEL
330 H2S / Total Sulfur Analyzer
This uniquely rugged and simple design by Envent utilizes a lead acetate based sensing system that provides a linear and interference-free output of H2S and Total Sulfur concentration.
APPLICATIONS
Measures H2S and/or Total Sulfur in natural gas, petrochemical streams, condensate, or LPG.
FEATURES
Ranges from 0–50 ppb to 0–100%
1.5% accuracy, 1% repeatability
Modbus Serial communications,
Displays up to 5 times full scale
Dual Isolated 4–20 mA outputs
less than 20-second response time to alarm
Interference-free Lead acetate sensor
60–90 day tape (longest tape life in the market)
Optional CO2 Sensor
Optional Total Sulfur
The 330 measures H2S in natural gas or other process streams. The unit has dual 4–20 mA outputs, dual measurement alarms, plus trouble and fault alarm relays. An external magnetically-driven interface allows operator functions without opening any covers. The 330 displays H2S concentration in user specified units and as well will auto range to 5 times the lower calibrated range. Calibration is performed manually via the operator interface or automatically when connected to a calibration bottle with the optional auto calibration solenoid. The 330 is available with a number of optional sample systems and accessories to handle various applications such as high range H2S, Total Sulfur or H2S in liquids.
Lead Acetate Sensors: Lead acetate is essentially interference free from other sulfur compounds. This is why it is used by the vast majority in the industry when accurate measurement is required. The linear output enables the user to perform a single point calibration.
Longest Tape Life: The 330 offers the longest tape life in the market by using a proprietary tape advance algorithm to make complete use of the 300 foot tape. The unit will accept up to a 350-foot roll. Envent sensing tape is the strongest in the market.
模型
330 H2S / 总硫分析仪
Envent 这种独特的坚固而简单的设计采用基于醋酸铅的传感系统，提供 H2S 和总硫浓度的线性且无干扰的输出。
应用
测量天然气、石化物流、凝析油或 LPG 中的 H2S 和/或总硫。
特征
范围从 0–50 ppb 到 0–100%
1.5% 准确度，1% 重复性
Modbus 串行通讯，
显示高达 5 倍满量程
双隔离 4–20 mA 输出
报警响应时间小于 20 秒
无干扰醋酸铅传感器
60-90 天磁带（市场上最长的磁带寿命）
可选 CO2 传感器
可选总硫
330 测量天然气或其他工艺流中的 H2S。该装置具有双 4–20 mA 输出、双测量警报以及故障和故障警报继电器。外部磁驱动接口允许操作员在不打开任何盖子的情况下使用。 330 以用户指定的单位显示 H2S 浓度，并且自动量程为校准范围下限的 5 倍。校准可通过操作界面手动执行，或在连接到带有可选自动校准螺线管的校准瓶时自动执行。 330 可提供多种可选的采样系统和附件，以处理各种应用，例如液体中的高浓度 H2S、总硫或 H2S。
醋酸铅传感器：醋酸铅基本上不受其他硫化合物的干扰。这就是为什么当需要精确测量时，行业中的绝大多数人都使用它。线性输出使用户能够执行单点校准。
磁带寿命：330 通过使用专有的磁带推进算法来充分利用 300 英尺的磁带，提供市场上长的磁带寿命。该装置将接受高达 350 英尺的滚动。 Envent 感应胶带是市场上强的。
