Solvent gas sensor (LMG):

A Straightforward Solution
The LMG is a continuously measuring device for the determination of tiny amounts of solvent in air. As soon as an adjustable limit is exceeded a signal is given off.
 Application
Measurement of concentrations:
in soil vapour extraction from contaminated ground. Recording to writer or to PC.
Display when pollutants break-through on filters (e.g. activated carbon, biofilter etc.).
Concentration control of soil vapour suction wells:
Discontinuous suction of wells. The intervals that wells are active for can be controlled through measurement of the concentrations with the LMG. When extracting from a number of wells, coupling the LMG with automatic valves allows the unit to switch wells when concentrations dip too low.
Technical Data:  Comparison curve
Construction:
The LMG consists of 2 functional elements:
sensor and evaluation unit, air pump unit.
Outputs:
- Relay contact, up to 250V/4A
- Writer output 0 -1 mA, (4-20 mA)
Detectable substances (examples):
Per, Tri, 1-1-1 Tri, cis, MC, BETX, motor fuels and many more. |
