3300-39-004 CC 33 Fixed Transmitter with Xylene (C8H10), Aluminum Housing, 0-100% LEL (MK 208-3), RS 485 with Relay by GfG

It has always been our aspiration to combine innovative ideas and technology with functional design. This is how quality and longevity come about. Attributes symbolic of the name GfG in gas measurement.

Are you looking for an innovative transmitter for flammable gases, but need explosion protection? Then a transmitter from the GfG 33 series is the right choice.

Robust housing for every application

The transmitters of the 33 series are flameproof encapsulated and fulfill the requirements of the type of protection "d". Depending on the application, you can choose the 33 transmitter with an epoxy-based aluminum or a pure stainless steel housing. In order to meet the quality requirements of our customers and our own standards in terms of durability, we use a particularly high-quality and durable Viton seal in the 33 series. This can withstand even the toughest operating conditions for many years.

Variants

GfG offers the CC 33 in two variants:

For conventional industrial The CC 33 is available in a lacquered die-cast aluminum housing with 10mm thick bulletproof glass. Applications with special conditions such as e.g. in the Food industry can be covered by a unpainted housing made of stainless steel with a 15mm thick bulletproof glass.

Operation by means of magnetic pin

The three magnetic switches behind the protective glass, which is up to 15mm thick, can be operated using the GfG magnetic pin. The GfG typical three-button operation is easy to understand. The menu is clearly structured and logically structured.

All transmitters of the 22, 29 and 33 series have a uniform user interface. The uniform operation and the logical system structure keep your training and maintenance effort as low as possible.

Proven and innovative is not a contradiction

The CC 33 works on the principle of catalytic heat generation (WT), a proven method for measuring combustible gases. The transmitters are equipped with high-performance electronics for voltage stabilization, processing of measured value output and temperature compensation. The long life of the sensors minimizes follow-up costs.

Sensor technology

With improved sensor technology and the unique GfG "chimney effect", the CC 33 transmitter for combustible gases has one of the fastest response times in the world. There are more crucial seconds left to initiate countermeasures and to bring people to safety.

Universal signal transmission

The measured values and status displays of the 33 series can be transmitted either analog or digital via the Modbus interface. Due to the different variants of signal transmission, a transmitter of the 33 series can be connected to almost any gas warning system as an additional measuring point or in exchange for existing transducers.

Signal processing

The embedded software of the 33 transmitter linearises the measurement signal and compensates for temperature influences. As a result, correct measured values are transmitted even in the event of weather-related temperature fluctuations. The execution of the software enables the detection of faults and, in the Modbus variant, the requirement of required service or maintenance work.

Smart sensors

Pre-calibrated sensor modules can be screwed directly into the sensor receptacle on the housing of the CC 33. The smart GfG sensors are pre-programmed with all the necessary parameters and can be used without much effort ("plug and play"). Sensor changes are shown in the display. (catalytic and electrochemical sensors)

Three freely programmable internal relays

The 33er transmitters can be used as a "stand-alone system". You can set the two alarm thresholds individually and freely program the optional three relays. You do not need a cable to a controller and you can nevertheless reliably switch safety-related devices.

With colored graphic display

The clearly laid-out graphic display makes it easy to read the device status, the current measured value and many other important information. In the event of an alarm, the display turns red. The large LEDs signal from a distance the current device status and thus serve the rapid information of your employees about any alarms or malfunctions.

Using the display, you can easily navigate through the clear device menu and make various settings, including calibration, depending on your user authorization.

Calibration

For regular function control with gas application, a calibration adapter is placed on the transmitter to ensure a safe and even gas supply.

This will give you access to all settings and configuration options. After entering the password, changes can also be made using the control keys in the D-ReX's service menu.

Advanced connectivity

The D-ReX comes with a wide variety of communication interfaces: Choose between analog, industry standard 4-20 mA, digital RS-485 interface (Modbus/RTU), Ethernet (Modbus/TCP) and LonWorks (optional) for signal transmission. The Bluetooth option enables wireless connectivity. In addition to the five internal, programmable changeover contact relays (optional), 16 additional relays can be addressed by connecting the D-ReX to a GMA200-RT/D relay module.

Periodic sensor self-tests

The plug-and-play smart sensor cartridges are pre-configured and pre-calibrated for easy installation or replacement. Automatic sensor self-tests increase safety while reducing maintenance costs even further.

94055 Dew Heater Ring - 5" by Celestron

The Celestron Dew Heater Ring is the ideal dew prevention solution for your Celestron telescope. This must-have accessory will improve your observing or imaging nights year-round. The Dew Heater Ring permanently mounts to your 5" Celestron Schmidt-Cassegrain optical tube, replacing your retaining ring, so you'll never be caught without it. The installation process is quick and easy (follow the manual for instructions).

How it works

The Dew Heater Ring replaces the plastic retaining ring on your Schmidt corrector lens for efficient heating across the lens. The ring is constructed of lightweight, durable aluminum. Its rigid frame supports the cable circuity and the telescope's Schmidt corrector lens. Unlike other heating bands or strips that inefficiently heat the lens cell to warm the glass, the Celestron Dew Heater Ring heats the corrector glass directly, providing the most efficient transfer of heat to prevent dew formation.

Simply plug the ring into an external 12V DC power source for consistent, continuous heat that will prevent dew from forming even under heavy dew conditions. The Dew Heater Ring features two storage clips to keep the power and thermistor jacks secure when not in use while accommodating the telescope's dust cover.

The Dew Heater Ring also comes with a cable management clip that connects to the telescope's front cell. Corral the power and thermistor jack to prevent them from dangling and reduce unwanted pulls on the cable connection to the rings.

The Dew Heater Ring comes complete with:

• Dew Heater Ring
• Cable management clip
• Power jack extension cable
• Paper installation shield

Enhance your setup

To achieve the highest level of dew prevention while maximizing power efficiency, we strongly recommend pairing the Dew Heater Ring with a Smart DewHeater Controller (sold separately). The controller uses the ring's built-in thermistor and its internal environmental sensor to provide just the right amount of heat to the corrector to prevent dew based upon the ambient temperature, ambient humidity, and temperature of the Schmidt corrector, which can dramatically reduce the ring's power draw, greatly increasing battery life. The ring also includes an extension cable for connecting the ring directly to one of the controllers' heater output ports, or to a third-party controller's heater output port. (Note: the ring's integrated thermistor is only compatible with the Celestron Smart DewHeater Controllers).

We also recommend adding a dew shield to your setup. While not mandatory, a shield will cut down on the amount of power the Dew Heater Ring needs to keep the optics clear.

• Heater ring provides the most efficient heating directly to the corrector lens to prevent the formation of dew
• Permanently mounts to your existing telescope tube for a seamless look–plus, you'll never forget to bring it with you
• Integrated thermistor continuously monitors the temperature of the corrector lens when used with the Celestron Smart DewHeater Controllers.
• Rigid, lightweight, and durable aluminum construction
• Included storage clip and cable management clip keep your cables organized
