CS22-D CS22 Fixed Transmitter, Display / 4-20 mA 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 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.

1316009 G311 Single Gas Detector for Methane (Natural Gas), Propane, and Other MOS Detectable VOCs, with 4 AA Alkaline Batteries by GfG

Pinpoint the Smallest Leaks

Small leaks in pipes or storage tanks can release enough gas to build up dangerous concentrations. The careful inspection of flanged, threaded and soldered connections before and after installation will ensure equipment and worker safety. The G300 leak detector will make leakage sprays a thing of the past

Clear and simple displays and warnings

Changing gas concentrations are indicated audibly and visually. The frequency of the audible warning rises with gas concentrations, allowing the user to pinpoint leaks. The bar graph display will warn the user if dangerous gas concentrations arise.

Light, compact and durable

Designed for one-handed operation, the G300 reacts to concentrations as small as 5 ppm and measures up to more than 10,000 ppm or 1% volume. The sensor is located at the end of a flexible gooseneck or a helix cable to allow the user to reach difficult or unreachable locations. The G300 is available with or without explosion protection for ammonia and combustible gases. The G311 operates on four "AA" alkaline batteries. All others have a rechargeable battery with run times of more than eight hours.

2214018 CS 21 Fixed Gas Transmitter, HFC-23 (CHF3), 30 to 1000 ppm by GfG

The CS 21 transmitter uses the proven chemosorption detection principle for detection of toxic gases, vapors and combustibles. The rapid response of the transmitter provides opportunity to take counter measures and thereby limit damages. The long life of the sensors makes the CS 21 a low-cost solution for your detection needs. A transmitter can be continuously operated for more than 5 years.

Wall mount installation is straightforward. The distance between transmitter and controller can be greater than 500 m. A rugged aluminum casing protects the sensor and electronics from splashes of water and dirt. The transmitter must not be operated in EX-areas. For measurement of combustible gases in the LEL range the gas needs to be sampled by pump. In this case the EX-protection needs to be guaranteed with suitable external components (e.g.flame-protection).

2210-030 Dynagard 25 for O2 Stand-alone System with ZD 21 Transmitter for Detecting Oxygen (O2) and GMA 41B Single Channel Controller by GfG

Simple and Effective

The Dynagard 25 Series accurately measures oxygen levels. The unit offers a local display, a horn / strobe, and a linear 4-20 mA output. The Dynagard 25 Series offers a safe and reliable gas warning system.

Alarm Points

Each alarm can be adjusted separately. The alarm point values can be freely adjusted within the detection range of the transmitter. Every alarm point value can be set to over range / under range, latching / non-latching, or resettable / non-resettable.

Alarm Relays

The controller provides four voltage-free relays for the three alarms and one fault warning. The relays may be used to control additional alarm devices like lights or horns. They can even prompt specific counter measures to prevent or limit dangers from gases or vapors.

ZD 21 Zirconia Sensor

The comprehensive electronics allow for easy operation and maintenance and also increase operational safety and accuracy. In less than 2 seconds, the ZD 21 responds to an oxygen deficiency. The sensor has a platinum coating on the inside and outside of the ceramic cylinder. Oxygen is electrochemically reduced at the cathode.

The voltage produced is proportional to the next difference in the partial pressures of oxygen in the reference gas versus the sampled gas. This extremely short response time allows the user the time to take measures to prevent consideable damage.

Features

• Easy installation
• Local display and horn / strobe
• Adjustable alarm points
• On-board relays for external controls
