GENERAL MONITOR H2S气体传感器技术参数

GENERAL MONITOR H2S气体传感器产品介绍

GM的硫化氢（H2S）传感器是固态设备，其设计和制造具有长寿命和快速响应性。它们对H2S具有选择性，并且不受高浓度的其他物质（例如氢气，二氧化硫和汽油蒸气）的影响，这些物质通常存在于处理酸性气体和原油的设施中。

半导体器件测量由于气体暴露而导致的薄金属氧化物膜中电导率的变化。电导率的变化与目标气体浓度呈对数关系，并用于向控制器提供信号。薄膜的表面温度保持在100°C以上，以减少环境温度，湿度的影响并提高选择性。

金属氧化物半导体（MOS）传感器是General Monitors智能传感器和基于控制卡的H2S检测系统产品线的重要组成部分。传感器易于安装，并且可以通过使用预先混合的H2S与干燥空气的安瓿或一次性罐来方便地进行校准。几个附件通过保护它们免受水和灰尘的侵害或简化了它们在管道和采样系统中的安装，扩展了这些传感器的用途。

这些传感器对各种温度和湿度的高耐受性使它们能够在恶劣的环境中运行，以及它们在短时间内承受高H2S浓度的能力。

General Monitorsʼ hydrogen sulfide (H2S) sensors are solid state devices, designed and manufactured for long life and fast response. They are selective to H2S and remain unaffected by high concentrations of other substances like hydrogen, sulfur dioxide, and gasoline vapors, which are often present in facilities that process sour gas and crude oil.

A semiconductor device measures changes in electrical conductivity in a thin metal oxide film as a result of gas exposure. The change in conductivity is logarithmically correlated to the target gas concentration and used to supply a signal to the controller. The surface temperature of the film is maintained well above 100˚C to reduce effects of ambient temperature, humidity and improve selectivity.

Metal oxide semiconductor (MOS) sensors are an essential component of General Monitorsʼ line of intelligent sensors and control card-based H2S detection systems. The sensors are easy to install and can be conveniently calibrated by using ampoules or disposable canisters of pre-mixed H2S with dry air. Several accessories extend the usefulness of these sensors by protecting them against water and dust or facilitating their installation in ducts and sampling systems.

A high tolerance to a broad range of temperatures and humidity enable these sensors to operate in rugged environments, as does their capacity to withstand exposure to high H2S concentrations over short periods.
