Product Description

Intelligent Combustible Gas Detector

The Monicon S500L Gas Monitor is a rugged, self contained, Intelligent gas sensor with, many advanced features to provide fast, realiable warnings of combustible gas concentrations at levels below at which these gases become potentially explosive. The S500L is certified ATEX EEx'd IIc T6 Ta -20ºC to +60ºC.

The gas concentration is indicated locally on the dot-matrix LED display in the range 0-100% LEL. The S500L incorporates a 4-20mA analogue output, an RS485 computer interface and on-board alarm relays.

The sensor is available in catalytic, semiconductor or NDIR technology.

 Monicon Sencor T100 T100 Toxic Gas Transmitter (click here for more info) 

The T100 is a 4-20mA 2-wire transmitter can measure a wide range of gases and is housed in a rugged, compact metallic enclosure. It incorporates advanced SMD electronics and a 3 electrode electrochemical sensor based on micro fuel cell technology, designed to be maintenance free and inherently stable.

The sensor uses the highly successful capillary diffusion barrier technology, resulting in a low temperature coefficient and a direct response to concentration, relatively unaffected by pressure. The use of electrodes based on fuel cell technology gives a high reserve of activity which results in long term stability.

Gas diffusing to the sensor electrode reacts at the surface of the electrode either by oxidation (e.g. CO, H2S, SO2, NO, H2, HCN, HCl, C2H4O, NH3) or by reduction (NO2, O3 and Cl2). Reactions are catalysed by specially developed electrode materials and are designed to be specific to the gas being sensed

 Monicon CO2 Pic Sencor IR80  Monicon IR CO2 Monitoring Unit (click here for more info)

The Monicon IR80 is a high quality, self contained, NDIR (Non Dispersive Infra Red) gas sensor that offers a host of sophisticated features to provide fast, reliable warnings against exposure to dangerous concentrations of carbon dioxide.

The IR80 will operate as a standalone instrument or in conjunction with a controller or a computer. It is housed in an attractive, compact enclosure and may be configured or calibrated by one person.

The gas concentration is indicated on a rugged 8-character alphanumeric display which also indicates instrument status.

The IR80 is fully user programmable and no physical adjustments are necessary during calibration as the on-board computer assists the calibration procedure.

All user variables are stored in non-volatile memory (EEPROM) and retained indefinitely even during total power failure.

The IR80 uses advanced miniaturised NDIR technology combined with surface-mount microprocessor and firmware technology. A pulsed infrared source emits a broad spectrum infrared beam within an optical cavity. The system measures the adsorption of infrared energy as it passes through a gas sample. Different gases have clearly defined absorption characteristics, their concentration can be determined by their absorption of infrared radiation at the wavelength determined by filter lambda 1 in the diagram.

To compensate for interfering factors filter lambda 2 isolates another wavelength which is used to measure the total transmission through the optical cavity and is not affected by the gas being monitored. By comparing the infrared energy reaching each of the two detectors, the concentration of the gas sample can be determined. The signal processor compares and linearises these two signals. A thermistor monitors the sensor temperature and the signal processor factors in variations caused by temperature changes.Features
