Gas Sample Probe Series ASP

__Version ASP 6XX ATEX

sample probe

 Application

 

The ASP gas sample probes are designed for continuous gas sampling in difficult processes with gases of high or low dust content, different temperatures and extreme humidity.

 

Description

 

Due to its modular design and various options, the Ankersmid heated sample probe filters cover the widest range of applications. In the heated filter body a filter element of 150mm length, suitable for most applications up to 1g dust/m3, is integrated. A 180mm long filter with an outer diameter of 40mm and made of stainless steel can be optionally used for applications up to 4g dust/m3; with the blow-back function dust loads of up to 10g/m3 can be handled. For even higher dust loads, a primary filter has to be positioned as pre-filter.

A significant advantage is that all filters are replaceable without dismounting the probe without using any tools and in the shortest possible time. Cleaning and exchanging of unheated sample tubes or preliminary top-filters can be affected by extracting the filter from the probe.

The probe temperature with Exd-temperature sensor type Pt100 is controlled by an ATEX-certified controller-limiter unit with temperature alarm.
The probe is delivered with valid ATEX-certificates for all electrical components.

The following features are offered for all probes:
• Test gas can be injected directly into the probe according to EN14181 (regulation for calibration of emission monitoring systems) that enables calibration gas feeding via the filter element of the gas sample probe.
• Test gas can be injected into the probe through a check valve directly to the sample outlet so that no calibration gas is lost to the stack.
• An isolation valve with pneumatic control shuts off the sample outlet from the internal filter area in case of blow-back.
• Cleaning of filter and the sample tube through a high-flow inlet ports so less maintenance is necessary in high dust load applications. This inlet can be controlled by pneumatic or electric valves, and also in combination with a volume chamber for high pressure flow.
