2313001-1 GMA 313 Stand-Alone System, Basic Set for One Room Monitoring by GfG

State of the Art Technology

The best solution for CO2 monitoring fromthe specialists in gas detection. The GMA 313 indicates a gas hazard immediately and reliably. The built-in alarm LED and loud horn provide a warning before entering the room. The external alarm GMA 313 EQ also gives a warning wherever you want it, e.g. at the stairway or at the bar. The GMA 313 offers state-of-the-art sensor and microprocessor technology from a compact unit.

The sensor and electronics, horn and lights are integrated in one enclosure, thus saving installation costs. The robust casing is splashwater proof (IP 54), so splash-water cannot enter and damage the monitor. Thermostat control and temperature compensation of the sensor ensure reliable measurements and safety even in case of sudden temperature changes.

Low Maintenance and Long Lifetime

The infrared (NDIR) sensor has a considerably longer lifetime than an electrochemical CO2 sensor. The GMA 313 is low maintenance, robust, and reliable. Installation of the GMA 313 is very simple, just plug it into a standard 110 v ac wall outlet.

Infrared Principle

Carbon dioxide (CO2) absorbs light in the infrared range of the spectral. The NDIR technology of GfG's sensor detects the carbon dioxide concentration precisely and reliably. The infrared light emitted by a lamp passes through the gas sample. Carbon Dioxide absorbs the light in a narrow spectral range.

The remaining light is measured at the detector. The difference between emitted and detected light is proportional to the gas concentration. Water vapor and other gases, which may be presenting the sensor chamber, do not affect the light absorption in this spectral range.

Safe detection results, even with temperature changes. Precise optical measurement ensures the best accuracy and repeatability. The IR principle is as distinct as a fingerprint in criminology.

This means that only carbon dioxide is detected, thus eliminating false alarms from interfering gases. GfG Products use electronics with voltage stabilization and temperature compensation.

This results in stable measurement vales even with considerable temperature variations.

The GMA 313 has no moving parts which could be subject to wear and tear. This ensures a long lifetime and reduced service requirements. Permanent self-check of functional capability provides additional safety. Sensor and electronics are protected by a robust enclosure (IP 54).

2492001 IR 24 Fixed Gas Transmitter Carbon Dioxide (CO2), 0-5% Vol. by GfG

CO2 a toxic hazard

Carbon dioxide (CO2) is often used as a work medium, or is stored, shipped, or generated as a by-product of certain industrial applications. The specific characteristics of CO2 make this gas a hidden danger.

Carbon dioxide is odorless, tasteless, and undetectable to human senses. CO2 is considerably heavier than air and can rapidly build to dangerous concentra-tions in holes, sewers, or cellars. Concentrations as low as 4 percent volume can be toxic, and 8 percent volume CO2 can cause death. Carbon dioxide also displaces the oxygen content in the ambient air, which may lead to asphyxiation.

GfG Instrumentation's fixed gas warning systems allow continuous monitoring of gas hazards to ensure that countermeasures can be taken in time. A fixed gas monitoring system consists of a remote sensor which is connected by a cable to a controller such as the GMA 011, GMA 100, or GMA 300. The controller powers the remote sensor and evaluates its measurement signals.

IR24 for CO2

The remote sensor with its sensor cell is mainly responsible for the reliability of a gas monitoring system. The sensor is installed wherever CO2 may be present. Even the lowest gas concentrations can be detected and transmitted to a central control station as current or voltage signals which are proportional to the actual gas concentration.

IR24 detection principle: infrared light

Since carbon dioxide (CO2) absorbs light in the infrared spectral range, the NDIR method used in the GfG sensor can measure the carbon dioxide concentration precisely and reliably. Infrared light is sent through the sensor chamber. Carbon dioxide absorbs a part of this light in a narrow spectral range, and the remaining light is measured at the detector. The difference between the light sent and received is propor-tional to the gas concentration. Water vapor or other gases that can be present in the sensor chamber do not affect the light absorption in this spectrum band.

Durable construction for long lifetime

The IR24 does not contain any moving parts that are subject to wear and tear, ensuring a long lifetime, and low maintenance costs. More safety is provided by the permanent self-check and function test of the GMA controller. Sensor and electronics are protected in a solid enclosure from dust and water according to IP 54. This ensures that water cannot enter the detector, even in wet environments.

Easy handling

Behind a service lid on the front of the IR 24 are potentiometers and test connectors for easy adjustment of zero point and detection range. This allows one-person calibration on-site and reduces service down-time.

Quality control adds more safety

All remote sensors are made by GfG Instrumentation and have to pass a 100% quality and function test. All sensors are shipped pre-calibrated. An authorized GfG Instrumentation specialist makes the final adjustments during system installation.
