DOMINO - 1

Moisture-in-oil instruments The DOMINO is an accurate, simple, robust and versatile instrument offered by Doble Engineering. The DOMINO, Doble’s Moisture-in-Oil instrument, measures just that: moisture in oil in terms of ppm and relative saturation plus the added benefit of temperature. It is an instrument that provides for the continuous reliable measurement of the water content of electrical insulating liquids and other types of oils. Introduction: In 1999, Doble introduced the first DOMINO that became an instant success. Its enthusiastic acceptance in the industry has placed it as another respected, superior quality instrument provided by Doble Engineering. The success was due in main part to the variety of applications that it could be used. The variety of application uses, along with its robustness and Doble’s technical expertise have made the DOMINO an industry standard. In 2007, Doble introduced the second generation of DOMINO and has been very well received by the industry. The new generation of DOMINO brings a progression from just a basic sensor to an instrument with many enhancements and added features from the first generation. Features: Why Measure Moisture in Oil? The determination of moisture in insulating liquids is an essential part of any comprehensive maintenance or diagnostic program. Water is extremely detrimental to most oil filled systems and especially transformers and other liquid-filled electric apparatus. Knowing the water condition in real time is the best way to guard against harmful conditions that may exist or present themselves. • Instantaneous Results– no waiting...the DOMINO provides continuous results in parts per million (ppm), relative saturation and temperature on a single easy to read display and records the values in real time. • n Effective Monitor– continuously monitors A oil reconditioning in systems as small as a single filter cartridge to as large as a mobile or stationary processing plant. Helps in determining filter changeout, process efficiency, and determination of when to terminate the processing effort. Readout is directly in ppm—no need for messy charts and conversions. • S imple to Use– eliminates all harmful chemicals and laboratory systemic errors associated with Karl Fischer titrations, delicate Karl Fischer titration devices, sampling error, and contamination from ambient humidity. • QuickResponse – In flowing oil at a velocity of 4 liters per minute or more (1 gallon/minute), the time for 100% response is 30 seconds or less. This means you can perform your job quicker and more accurately. • E installation– the probe installs diasy rectly in the flowing oil up to 2271 liters per minute (600 gpm). As for the transmitter, just plug it in…it will start to measure and display immediately.

Models: The DOMINO incorporates many options in our base unit such as two or three selectable and scalable analog outputs and a serial bus. Most models include a keypad and display and are powered by either by 10-35 VDC/24 VAC or a 100-240VAC power supply. DOMINO models have various cable lengths from the probe to the transmitter (display/keypad), can be mounted permanently or temporarily. There are even three models that have an alarm output. These options enable you to fit the product to your needs. Cable Length Digital output Analog Outputs Alarm Relay The success of DOMINO has...
