2041001 GMA 41B Single Channel Controller, with Digital LED Display, External Reset Connection and Linear 4-20 mA Output by GfG

Gas Monitoring Controllers

Alarm points

Alarm relays

Features

• Single or four channel controller
• Easy mounting on DIN-rail
• Multiple alarm points with relays

Additional features

The GMA (variant B) offers an integrated BUS-system. The BUS-system supplies power from one source to all connected GMAs. The BUS-system also connects individual controller alarms together so that, with the use of the key-operated switch, all connected monitors have one collective alarm. Several GMAs can be connected easily without additional wiring.

1450-921 G400 Motorized Smart Pump Alkaline by GfG

Optimized Alarm System

The new G400 MP-2 pump continuously communicates with the G450/G460 gas detector. This interaction allows fault indication via the detector display. Alarms such as low battery, blocked sampling line or interrupted power fault are shown on the display and activate a visual and audible alarm on the monitor.

Various Applications

Gas samples can be taken from a distance of up 100 meters (over 300 feet) at a typical draw rate of 0.5 liters per minute.

Superior Flexibility

The G400 MP-2 is the only detachable pump on the market today which will allow for operation in both diffusion mode and remote sample-draw mode. Simply slide the shutter to turn the pump on or off. When the pump is on, the shutter covers the diffusion inlets and exposes them when the pump is switched off.

The G400 MP-2 features a high efficiency redundant filter system in addition to a standard external probe with dust and hydrophobic filters.

Independent Power Supply

The G400 MP-2 is operated by its own power supply, independent of the gas detector. The power supply of the pump allows for up to 10 hours of continuous operation.

Features

• Optimized alarm system: Visual alarm via the G450/G460 display and alarm LEDs, Audible alarm via the G450/G460, Vibration alarm via the G450/G460
• Allows monitor to be used in either pump or diffusion mode
• Independent power supply (does not reduce instrument battery capacity)
• 300 feet (100 meter) remote sampling capability

Includes

• 10' of Tubing
• Probe with Filters

22210-01 ZD 22 Fixed Gas Transmitter, No Display / 4-20 mA by GfG

Superior technology

The ZD 22 Transmitter is specifically designed for long-term monitoring of oxygen concentrations. The integrated amperometric oxygen sensor is based on an electrochemical oxygen pumping cell made of zirconium dioxide. It is characterized by its robustness, a very high life expectancy and its outstanding long-term stability. The integrated thermostatic control of the sensor element achieves accurate measuring results in the entire temperature range, regardless of the operating temperature. It can also be permanently used in environments with high concentrations of CO2 or in dry atmosphere. Special equipment is available to protect the transmitter when used in harsh environments.

Signal processing

The protective casing (IP 54) of the ZD 22 Transmitter contains the complete signal processing electronics and the failsafe routing of the measurement signal for the measuring computer, with extensive self-monitoring. The embedded software linearises the measuring signal and compensates for the effects of temperature. As a result, correct readings are transmitted even with weather related fluctuations in temperature. In addition, the transmitter can be connected to a gas measurement computer for the option of transmitting service, maintenance, and error messages.

Universal signal transmission

The ZD 22 Transmitter transmits the signals either using an analog (0.2 1mA / 4-20 mA) current interface or a digital (RS485) Modbus interface. This permits the universal use of the trasmitters in combination with GfG gas measurement computers and thus connection to a safety system, so that you and your systems will benefit from the best possible protection.

There are a variety of applications for the ZD 22 in regard to sensors, status LEDs and optional analog or digital interface, "Zero" key to calibrate the zero point, test socket and a potentiometer for the calibration of the sensor.

Weather protection

A weatherproof housing not only protects transmitters against exposure to wind and weather, but also against contamination and excessive temperatures caused by direct sunlight.

Optional colored graphic display

The clear graphic display of the ZD 22 is self explanatory and allows you to read the current status and other important information with ease. The display enables you to navigate effortlessly through the unit s concise menu and to change settings or even calibrate, depending on your user authorization. In the event of an alarm the display changes color from green to red. Two LEDs indicate the status.

Operation buttons

The buttons on the transmitter allow the unit to be calibrated and settings to be adjusted through the menu as needed.

Calibration adapter

In order to perform a calibration, a calibration adapter is used on the transmitter, which ensures a uniform and secure supply of gas.

Easy and convenient service

GfG offers full after-the-sale commissioning and field service support.

• Long service life of the sensors
• Extremely fast response time: t90 < 5 sec.
• Reduced pressure, humidity, or temperature influence
• No damage due to CO₂
• Cost effective single-man adjustment
• Affordable operation costs
