Ex defined: The generic term of all methods of protection IX/iised in Europe, "Explosiongeschutzen," is used to cover all techniques of protection. Electrical equipment installed on oil rigs, in oil refineries, and similar places has long been recognized as a potential explosive hazard due to the risk of sparks or hot surfaces igniting the highly flammable gasses or vapors which may be present. Early recognition of these potential hazards led to many of the industrialized nations developing standards for construction and testing of such apparatus. • Designed to CENELEC Standards; EN 50 014, 016, 018, 019 and 020 • Certified for Europe by BASEEFA, PTB, NEMKO, DEMKO, and INTEX • Recognized by 17 countries in the European community • Meets or exceeds many international inspection and approval agency standards

The Martin-Decker Purged/Pressurized System With the Martin-Decker system, pressurization is maintained by leakage compensation which is achieved by topping-off the system to maintain pressure, resulting in considerably less air usage. Beside explosion-proof versions of standard instrumentation, Martin-Decker offers a full line of explosion-proof support equipment. Consult your Martin-Decker sales representative for specific requirements. For additional information, request data sheet P-203.

Explosion Protection Techniques Martin-Decker offers four different types of instrumentation, covering the three basic methods of explosion-proof ing to meet those safety needs.

Method 1. Prevention of the gas/oxygen mixture coming in contact with the source of ignition. Type of Protection Pressurization

Symbol Ex'p'

Apparatus is..... pressurized with air or inert gas

Method 2. Elimination of the spark energy to a level well below the minimum needed to ignite the flammable mixture. Type of Protection Increased Safety Intrinsically Safe

Symbol Ex'e' Ex'i'

Apparatus is..... non-sparking plus additional measures taken to ensure safety. Capable of causing only very small sparks, which are less than required to ignite explosive gasses.

Method 3. Other methods. Type of Protection Flameproof

Symbol Ex'd'

Apparatus is..... Containment of the explosion in a strong box enclosure.

DRILLING RIG INSTRUMENTATION

The M/D-3200 THE FIRST RIG DATA PROCESSOR BUILT WITH OILMEN IN MIND If you can read and punch buttons, you can instantly have information from up to 29 separate drilling parameters at your fingertips. The M/D-3200 not only gives you raw digital data readouts, it gives you analog charts of all drilling parameters to let you see conditions at a glance, to help you spot trends, and make drilling safer and more efficient. SIMPLE TO USE

The M/D-3200 is completely self prompted. This means that if you're not sure what to do next, all you have to do is punch the "HELP" button. The M/D-3200 will ask you what you want to accomplish, then tell you exactly how to doit. But just because it's simple to operate doesn't mean it's short on capability. The M/D-3200 is one of the most powerful and versatile rig data processing systems on the market. Basically, the M/D-3200 is made up of a processor, a CRT video screen, Print-O-Graph dot matrix printer (POG), an Analog Signal Conditioner and a Line Regulator to protect the unit from fluctuations in the power system. The CRT-monitor displays up to 29 separate parameters in an easy-to-read dot matrix format on a 15" screen. The unit will accept line variations from 100-135V AC at frequencies from 47 to 63 Hz.

CRANE LOAD MONITORING SYSTEM, Advanced system provides more reliable indication of crane operations at a lower cost.

Now, with better features than ever, the Martin-Decker CLM System gives the operator all the information needed for optimum efficiency during crane operation. The new system uses the latest rugged, reliable boom-mounted sensors and accurate, advanced electronics to acquire, relay and display hook load, maximum rated load, boom angle and hook radius. A continuously operating electronic system calculates all these factors, and quickly displays them to the operator with no guesswork. Fast-reading digital displays combine with warning lights and an audible alarm to call attention when approaching crane's rated load. The CLM utilizes the latest advances in large scale integrated circuitry, and offers greater reliablility with fewer components for the most efficient crane indication system to date. Because there are fewer parts, it's easier to install, calibrate and maintain without excess cabling and auxiliary power systems. And, it's less expensive than previous systems without sacrificing quality construction or dependability.

M/D-4200 ANCHOR LINE TENSION DATA PROCESSING SYSTEM Now you can monitor tension on up to ten anchor lines with electronic precision, and have an automatic hardcopy in either print or graph format. The M/D-4200 is made up of a processor, a CRT, an Analog Signal Conditioner and Line Regulator to protect the system from power fluctuations. For a permanent hardcopy of anchor tension, the PrintO-Graph (POG) will print either digital values, or graph tension in an easy-to-read chart format. The POG sample rate is also operator selectable. When seas are calm, one sample every half hour may be sufficient, but in heavy seas, when more frequent samples are necessary, the operator may select a sample rate of one second. When tension on any anchor exceeds the alarm limits set by the operator, the CRT will automatically reverse video (switch to black digits on a white background) and,

if desired, sound an audible alarm. In the Priority Alarm mode, the graph limits expand to full scale, giving you precise resolution for alarm conditions. Finally, the M/D-4200 is completely self-prompted. Which means that if you aren't sure what to do next, all you have to do is punch the "HELP" button.

The simple design of the MartinDecker load cell has only one moving part. • Friction-free stroke transmits direct, signals. • Nothing to plug in; no power source required. • Capacities to 300,000 Ibs. for tension and compression cells. • Accurate to 0.2 of 1% of full scale. • Available in dial indicator sizes from 6" to 18". To order—Specify: Capacity, dial size, hose length, tension or compression system. 26

HYDRAULIC CRANE SCALES

Eliminates costly trips to a central weighing station by accurately weighing loads as they are lifted. Based on a rugged load cell design, built to withstand shock loading and continuous vibration. Available in capacities ranging from 0-1,000 to 0-200,000 Ibs. • Installs by simply hanging on an overhead crane or hoist. • Accuracy: 0.2 of 1%; can be calibrated to 0.1 of 1% for commercial use. • Available in Metric, English, and reverse-reading batching dials. • Remote indicating models available. To order Specify: Capacity, indicator dial size, remote reading, metric, reverse-reading model0

LIFT TRUCK WEIGHT INDICATOR WITH ADJUSTABLE FULCRUM

Speeds workflow by turning any lift truck into a mobile weighing station; eliminates the problem of truck overloads. Adjustable fulcrum enables in-shop calibration in only 10 minutes—no need for factory recalibration. Dial indicator gauge uses the hydraulic lifting system of the fork lift as the load sensor. Does not require use of a load cell. Installation takes less than one hour on most lift trucks. Can be recalibrated on the truck in minutes without removing gauge. • On trucks with a capacity of over 4,000 Ibs., average installation performance accuracy is 1% of full scale. Accuracy is dependent upon condition of lift hydraulics. • Capacities to 100,000 Ibs. • Manual tare adjustment to zero out weight of forks, containers, pallets, tote boxes, etc. • Easy-to-read dial with pulsation damper placed at operator's eye-level. To order Specify: Capacity, dial indicator size, make, model and serial number of truck, serial number, type and lift ratio of mast.
