Gas Sample Probe Series ASP
Due to its modular design and various options, the Ankersmid heated sample probe filters cover the widest range of applications. With a choice of different lengths of heated filter body, a filter element of 150mm length, suitable for most applications up to 1g dust/m3 can be integrated. 180mm filters with a larger filter surface are used for applications up to 4g dust/m3; with the blow- back function dust loads of up to 10g/m3 can be handled.
The 500mm model filter of the ASP 1500 has a capacity for dust up to 10g/m3. When this type is equipped with blow-back option, it handles up to 20g/m3. For even higher dust loads, a primary filter is positioned on top of the first 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 is controlled by a microprocessor based PID-controller (optional with Modbus/RS485 communication). Alarm or fault contacts can be programmed and the temperature can be changed easily. The standard sensor is PT100, whereas a thermo-couple is standard for the high temperature version.
Description
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.
As the ASP is available in different lengths, it is suitable for applications with low to very high dust loads.
Depending on the acid dew point, the standard probe operates at 180°C or when necessary with a high temperature version at 320°C (f.e. Denox applications).
