2200-006 GMA 200-MT6/6 GMA 200 Controller, configured for 6 measuring points by GfG

For more than 50 years, the key goal of GfG has been to meet the highest demands of occupational health and safety, industrial equipment reliability and environmental protection. This goal has been reached by developing innovative and reliable gas warning systems. Development of the new GMA 200 gas warning system satisfies these requirements while taking into account suitability testing in line with ATEX Directive 94/9/EC. If switching functions for explosion protection are required, the GMA 200 gas warning system is the optimal solution. It also meets the requirements for gas warning systems without necessary ATEX certification and functional safety requirements (SIL).

Design of the GMA 200 gas warning system

The design of the GMA 200 gas warning system ensures flexible and simple operation in industrial and commercial applications for measuring combustible and toxic gases / vapors, and for measuring oxygen concentrations. The compact design of the GMA 200 as a DIN rail module enables cost-effective and space-saving installation.

Modular design of the GMA 200 MT6 / MT16 gas warning system

Up to 16 detectors can be connected to the GMA 200 gas warning system. A software program enables the quick and easy configuration of the measuring points for already installed GMA 200 gas warning systems. Measuring point designations, the detector type, the type of gas and measuring range as well as three individual or specified alarm thresholds can be programmed for each measuring point using the configuration software. A microprocessor evaluates the analog input signals of the connected detectors.

Integrated relays

As a result of the increasing requirements being placed on safety measures, even redundant protection against gas hazards, complex gas warning systems are in demand. The GMA 200 gas warning system is equipped with 8 internal relays. 6 relays can be freely configured using the software program in order to implement safety measures and alarms. The configuration software offers numerous and flexible options, such as the assignment of one or several measuring points to relays, single alarms per measuring point and alarm threshold, configuration of collective or group alarms and fault messages and voting functions. Two further relays are available for safety-related fault messages and for maintenance.

Relay modules

Using a GMA RT relay module, it is possible to extend the GMA 200 gas warning system by 16 additional freely configurable relays. A total of 4 additional relay modules and thus 64 additional relays can be managed via the GMA 200 gas warning system. Digital connection of the GMA RT relay module to the GMA 200 gas warning system enables the local positioning of the relay modules. The local and thus flexible installation of the relay modules results in large cost savings due to reduced cabling and assembly functions.

Availability of the gas warning system

Besides the traditional voltage supply, the GMA 200 gas warning system can also be operated with a redundant, safety-related voltage supply and therefore meets the highest demands of functional safety and the required permanent availability of gas warning systems for detecting potential gas hazards.

System functions: LED displays

The status of the GMA 200 gas warning system operation, fault, service is shown via LEDs.

Graphical display

The clearly structured layout of the GMA 200 gas warning system enables the quick detection of hazardous situations. Currently measured values are permanently displayed on the LCD graphical display. In the event of gas alarms, the display lighting is automatically activated with a red background.

Additionally, the LED display for Alarm 1, Alarm 2, Alarm 3 is shown. In the event of an alarm, the status of the active relays 1-8 is displayed simultaneously via LEDs.

The integrated memory enables the reading of alarm levels and minimum / maximum values per measuring point at the LCD for an initial, quick hazard assessment.

Data logger function

The GMA 200 gas warning system can be equipped with a micro SD card for saving the measured values. The measured values, mean values, alarm events and faults are permanently stored at individually configurable intervals, and can be read out for evaluation.

Operation via keyboard

Five buttons enable operation at the GMA 200 gas warning system. The main functions of the keyboard are the acknowledgement of alarms and the menu-driven operation. Information on the status of the gas warning system, detector and the relays can be retrieved in the operating menu.

Configuration

A USB port at the GMA 200 gas warning system can be used for connection to the configuration software.

6PIIFCE Conductivity/pH/ORP/TDS/Temperature/Resistivity Meter by Myron L

Since 1957, the Myron L® Company has designed and manufactured highly reliable analytical instruments for a wide variety of applications. Thousands of professionals around the world rely every day on the performance of our instruments. Demanding uses range from boiler water testing to ultrapure water control to medical instruments for artificial kidney machines.

We are proud of the trust our handheld instruments and monitor/controllers have earned in the past. Our product line has evolved to a new level of outstanding performance and value in analytical instruments: the Ultrameter II series. While priced like affordable single parameter instruments, the Ultrameter II does the job of three, four or even six instruments.

NEW! FC^E FAC Function

The Myron L® Company FC^E function reports FAC quickly and accurately by measuring ORP, the chemical characteristic of chlorine that directly reflects its effectivity, cross referenced with pH. Both DPD kits and colorimeters may tell the user the FAC value of the sample in the test tube, but since the chemistry of that sample is quite different from the source water being analyzed, the results are imprecisely related to actual disinfection power. The Myron L® Company FC^E function measures the real, unaltered chemistry of source water, including moment-to-moment changes in that chemistry.

Accuracy You Can Trust

Both Ultrameter II models deliver performance of ±1% of reading (not merely full scale). This high level of accuracy has been achieved through advanced four-electrode conductivity cell technology, a unique pH/ORP sensor and powerful microprocessor-based circuitry. With displayed values of up to 9999, the full four-digit LCD ensures resolution levels never before possible in such affordable instruments. Factory calibrated with NIST traceable solutions, each Ultrameter II may be supplied with both certification of traceability and NIST traceable solutions for definitive calibration.

Innovative Engineering

The Ultrameter II is a prime example of how high-tech engineering can greatly simplify and streamline a task. Whether in the lab, industrial plant, or in a remote field location, merely:

• Fill the cell cup
• Push a parameter key
• Take the reading

Temperature compensation and range selection are both rapid and automatic. The Ultrameter II is a true onehand operation instrument.

Easy to Calibrate

All calibrations are quickly accomplished by pressing the ▲ or ▼ keys to agree with our NIST traceable Standard Solution. When calibration is necessary, display prompts simplify pH calibration and make sure the correct buffer is being used. Plus, all parameters (excluding factory-set temperature) have an internal electronic setting that can be used for field calibration and as a check on pH/ORP sensor life.

Features

• Choice of KCl, NaCl, and 442™ Natural Water Standards
• ORP mV to ppm free chlorine conversion (6PFC^E)
• pH/ORP Sensor protective cap (6PFC^E)
• Four-digit display for full 9999 readings, with autoranging capability up to 200 mS/200 ppt
• Powerful microprocessor based surface-mount circuitry
• Display prompts for simple pH calibration
• Real Time Clock
• Memory for 100 readings with Date & Time Stamp
• Factory calibrations stored in microprocessor

Advanced Features

• 3 solution standards for greatest accuracy in diverse applications
• Fully automatic temperature compensation
• User adjustable temperature compensation (up to 9.99%/°C) which also allows TC to be disabled for applications requiring non-compensated readings.
• User adjustable conductivity/TDS conversion ratio for greater accuracy when measuring solutions not contained in the microprocessor.
• Auto-shutoff maximizes the life of the single 9V battery to more than 100 hours/5000 tests.
• Non-volatile microprocessor provides data back-up, even when the battery is changed. This assures all calibrations and memory data will be retained.
• Extended life pH/ORP sensor is user replaceable in the field.

Multiple Applications

• Irrigation Water
• Hydroponics
• Laboratories
• Wastewater
• Reverse Osmosis
• Deionization
• Cooling Towers
