FS 1 0 0 0 0粉尘排放流量开关

除尘器和袋式房子的排放已成为一个重大的环境问题。 巴比特有两款产品监视这些进程，并协助减少粉尘排放水平。 FS10000流量开关报警和/或关闭一个除尘器弱过滤器检测时之前，它成为一个重大的失误和粉尘的排放源。 随着“金融时报”4100流量变送器，粉尘排放浓度可测的手段，连续记录的排放数据。 FT4100符合EPA标题V参数监测的要求。

FS10000设计，检测和报警的灰尘流量通过在除尘器或袋式过滤器。 在某些情况下，它也可以被用来作为流量/无流量开关，用于在槽或气动输送线的粉末和颗粒剂。

当颗粒碰撞传感探头，一个小的电荷被转移到探头和感觉到通过FS10000的专用电路。 这被称为电荷转移的摩擦效应，或“摩擦电”。 FS10000可以检测除尘器排放之前，他们是可见的。

FS10000的输出是通过一个板上的继电器，可用于发出警报声，或执行其它控制功能。

FS10000的特点包括：

• 固态，没有运动部件。
• 简单的安装和校准。
• 无光学或镜头清洁或对齐。
• NEMA 4X外壳电子。
• 可选NEMA 7或9机箱。
• 防爆外壳探头。
• 现场可调延时。

典型应用

• 检测撕裂除尘器的过滤器。
• 织物或滤芯过滤检测。

FS10000是专为速度每分钟1800英尺或更大的应用。 要计算速度，当你知道CFM，使用下面的公式：

所有必要的校准指标均安装电子遥控器上的，所以你需要校准FS10000是一个小的螺丝刀。 一个没有流量的情况下进行校准。 每个单元都有一个字段，也可以使用商品饲料中忽略的滋扰标志或间歇中断的可调延时。

FS10000自带完整的电子电路板安装在一个NEMA 4X外壳，15英尺的低噪声同轴电缆和连接器，和316不锈钢探头安装在一个防爆外壳。

一个可选的屏蔽屏幕探头。 屏蔽屏幕被设计用于保护探头从在管道中，可能是由附近的风扇或电机的不必要的电噪声。 它也可以屏蔽探头从流浪创建的静电电荷的非金属管道。 的的屏蔽屏幕渗出到地的电噪声，才达到的探头，同时允许在空气流中的灰尘碰撞传感探头。

Emissions from dust collectors and bag houses has become a major environmental issue. Babbitt has two products which monitor these processes, and assist in reducing the level of dust emissions. The FS10000 Flow Switch is able to alarm and/or shut down a dust collector when a weak filter is detected BEFORE it becomes a major failure and source of dust emissions. With the FT 4100 Flow Transmitter, dust emission levels can be measured with the means to continuously record the emissions data. The FT4100 meets the requirements of EPA Title V parameter monitoring.

The FS10000 is designed to detect and alarm the flow of dust through a filter in a dust collector or a bag house. In some cases, it can also be used as a flow / no-flow switch for powders and granulars in chutes or pneumatic conveying lines.

When particles collide with the sensing probe, a small electrical charge is transferred to the probe and sensed via the FS10000's proprietary circuitry. This charge transfer is called the triboelectric effect, or "frictional electricity". The FS10000 can detect dust collector emissions before they are visible.

The FS10000's output is via an on-board relay, that may be used to sound an alarm or perform other control functions.

Features of the FS10000 Include:

• Solid state, no moving parts.
• Simple installation and calibration.
• No optics or lenses to clean or align.
• NEMA 4X enclosure for electronics.
• Optional NEMA 7 or 9 enclosure.
• Explosion-proof housing at probe.
• Field adjustable time delay.

Typical Applications

• Detect torn filters in dust collectors.
• Fabric or cartridge filter sensing.

The FS10000 is designed for applications where the velocity is 1800 feet per minute or greater. To calculate velocity when you know the CFM, use the formula below: 

All necessary calibration indicators are on the remote mounted electronics, so all you need to calibrate the FS10000 is a small screwdriver. Calibration is performed under a no-flow condition. Each unit has a field adjustable time delay that may be used to ignore nuisance indications or intermittent gaps in product feed.

The FS10000 comes complete with the electronic circuit board mounted in a NEMA 4X enclosure, 15 feet of low noise coaxial cable and connectors, and a 316 stainless steel probe mounted in an explosion-proof enclosure.

An optional Shield Screen is available for the probe. The Shield Screen is designed to shield the probe from unwanted electrical noise in the duct that may be caused by nearby fans or motors. It can also shield the probe from stray static electrical charges created in non-metallic ducts. The Shield Screen bleeds the electrical noise to ground, before it reaches the probe, while allowing the dust in the air stream to collide with the sensing probe.
