CC22-750 CC 22 Series Fixed Transmitter with Ammonia (NH₃) Sensor, 0 - 4% vol. Range, No Display / 4-20 mA by GfG

Are you looking for an innovative and cost-effective transmitter for combustible gases, but without the need for explosion protection? Then a GfG 22 series transmitter is the right choice.

Time-proven and innovative

The CC 22 works according to the heat of reaction principle, a proven method for measuring combustible gases. The transmitters are fitted with high-performance electronics for voltage stabilization, processing of readings, and temperature compensation. Follow-up costs are minimized thanks to the long lifespan of the sensors.

Universal signal transmission

Either an analog or digital output signal can be transmitted by the CC 22 by means of a Modbus interface. Due to the different types of signal transmission, a 22 series transmitter can be connected to almost any gas detection system, also as an extra measuring point or as a replacement transmitter on existing systems.

Signal processing

The embedded software of the CC 22 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. The software allows problems to be detected, and the Modbus version also indicates any required service or maintenance work.

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 CC 22 is self explanatory and allows you to read off 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 will turn red.

Operation buttons

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

The application areas of the dust and water-protected structure range from production and storage areas to disposal sites, biogas plants, mines and oil rigs.

Calibration adapter

In order to perform regular bump tests, 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.

Features

• Uses the catalytic combustion principle
• Long service life of the sensors
• High efficiency and low follow-up costs
• Sturdy plastic housing (IP 54)
• Cost effective single-man adjustment
• Affordable solution for many measuring tasks

CS22-701-M CS22 Fixed Transmitter, R-134a, no display, Modbus, 0(30) - 5,000 ppm by GfG

Wherever toxic or flammable gases and vapors must be monitored without requirements for explosion protection, the use of the CS22 is recommended.

Proven and cost-effective

The CS22 works on the principle of chemisorption (CS). Thanks to a wide range of monitorable gases and multiple measurement ranges, the CS22 offers a wide range of uses, from laboratories to industrial applications to refrigeration systems.

Transmitters with electrochemical sensors (EC), are also used with toxic and flammable gases. In contrast, the CS22 is a much more durable and cost-efficient solution. However, the environmental parameters must fit.

Communicates analog and digital

The measured values and status information of the CS22 can be transmitted either analog (4-20 mA or 0.2-1 mA) or digital (RS-485). This allows not only the use in combination with any GfG controller, but also the connection to programmable logic controllers (PLC).

Smart measured value processing

Industry-wide, the trend is towards smart units, such as the CS22, whose integrated electronics process the data already at the measuring point. The linearization of the measurement signal, compensation of temperature influences, detection of malfunctions and information on the next service or maintenance interval are just some of the advantages that result.

Variants for every requirement

The basic version of the CS22 is sufficient for many applications. If a measured value display on site is desired, there is also a variant with display and acoustic alarm.

CS22 Basic variant for a wide range of catalytic sensors
CS22 D with display to show the current measured value

In combination with GfG's powerful controllers, both variants are the right choice for a wide range of gases to be monitored.

A simple, two-button menu and a large, easy-to-read display provide easy menu navigation and reliable information even under difficult conditions.

Suitable for long periods of use

Depending on sensor equipment and configuration, the G222E has an average operating time of up to 9 months at 10 hours per working day or 90 days in 24/7 operation. The battery of the G222E can be changed in seconds if necessary and the gas detector is ready for use again.

Data logger

The internal data logger stores the last 2600 events. These include measured values, alarms, TWA and STEL values, and time as well as temperature information.

Calibration Cap & Smart Cap

Calibration and adjustment of the G222E are quite simple. All you need is the Calibration Cap for manual zero and test gas application.

If you want to read out the content of the data logger, you will need the Smart Cap, a USB connection cable and the Config Software for the G222 series instead.
