Air Monitoring 15
Monitoring System for Combustion Optimisation and Control
MRU is a leading manufacturer of industrial process gas measurement and emission monitoring systems. The price increase of fuels is causing boiler and furnace operators to search for ways to decrease the excess air of burners to reduce the heat loss and nitrogen oxides emissions.
The new in-situ probe OMS420 is used for continuous measurement of oxygen and combustible gas concentrations in stacks of various industrial boilers or furnaces, with fast response signal, ideally suited for combustion optimisation.
Beside standard zirconium sensor for oxygen measurement, the probe can be equipped with a new technology, heated solid electrolyte sensor for combustibles COe (CO equivalent) measurement.
The OMS420 probe is manufactured to a compact and reliable, rugged industrial design, whilst being easy to operate and maintain. There is no need for reference air, this instrument performs true wet gas analysis for fl ue gases up to 1700°C. OMS420 offers a fast response time and low energy consumption of both O2 and COe sensors. The probe offers fast and easy servicing and sensor replacement, without removal of probe from the stack; the transmitter or sensors are replaceable in the fi eld within a minute!
MRU offers an optional compressed air back-purging for high dust sites and optional auto calibration. Also available are application customised models like compact probe, remote transmitter probe and very high temperature probe, to accomplish various sites measurement request.

42286pr@reply-direct.com New Triboelectric Dust Monitor
Standard triboelectric technology is based on the DC signal, which is caused by particles making contact with the sensor to transfer charges. Compared to DC based measurements, the AC based technology is much more sensitive and mitigates the infl uence of sensor contamination which is of huge benefi t for industrial applications. By using AC based Inductive Electricity Technology it is possible to reach dust concentration measurement thresholds as low as 0.01 mg/m3.
The Basic Triboelectric ETG Tribo Dust Mini 485 it’s composed of a probe with an electrode. The communication between the probe and the Main board it’s performed by a couple twisted wires by a digital communication. The Electrical power to the probe is supplied to the Main board with the twisted wires. The welded base is durable Stainless Steel, whilst screeen is connected from probe to Main board via cables.
The Main board microprocessor manages several functions thanks to its digital display such as: Warm up, Last software release, test probe , programmable start delay, instantaneous value, average value, remaining time to the last average, minimum & maximum value, threshold alarm on instantaneous or average value, analogic full scale value, internal diagnostic, calibration procedure.
Main Applications: bag fi lter management in the wood industry, cement manufacturing, metallurgical, sulphur plant, dust control system for the smelter industry, emission monitoring in the bioethanol, chemical, and power industries, ESPY coal fi red power plant, process monitoring in the chemical, steel, and pharmaceutical industries, RF Network (Paper Machinery), and steel manufacturing.
