    • OMD-7 MK II

    • The OMD-7 Monitor was designed and developed by Deckma Hamburg GmbH, specifically for industrial & offshore applications. The performance and specifications of the OMD-7 comply with IMO Resolution MEPC.60 (33). The OMD-7 MKII is the first Industrial Oil-in-Water Monitor capable of distinguishing between the different characteristics of Oil particles, Solid particles and Water Turbidity on a continuous basis. The OMD-7 is comprised of a compact Measuring Cell, Monitor (with integral Computer Unit), Monochrome Alphanumeric Display and a proven Sample Conditioning Unit (SCU) for sample processing. The Measuring Principle of the OMD-7 MKII is based on the internationally known “Scattered Light Principle”.

Specifications

   
     

Applications

 

Liquids with low water solubility ie. Diesel oil, petroleum products, synthetic oils, vegetable oils, several chemicals etc.

Non-oil, solids contaminations ie. dust, grinding powder, sand etc.

Water turbidity measurement ie. water pollution monitoring etc.

Measuring principle

 

Different wavelength light scattering, (polychrome) multiangle measurement

Range (oil only)

 

0-200 ppm, other ranges on request

Accuracy

 

Better than ±5 ppm or ±10% of reading (whichever is greater). Accuracy can be increased optionally by calibration against a specific oil (e. g. up to ±2 ppm or ±5 % of reading (whichever is greater) for Diesel Oil.

Range (solids only)

 

0-800 smu (Solid Measuring Unit, equals 0-800 ppm Test Air Cleaner Dust according to I.M.O), or equivalent content of other solids, depending on solid density.

Accuracy

 

Calibrated against a specific solid: ±5 ppm or ±10% of reading (whichever is greater).

Absolute: ~50%, based on different bulk-densities

Range (turbidity)

 

0-1000 FTU (Formazin turbidity units)

Accuracy:

 

±5 FTU or ±10% of reading (whichever is greater)

Range (oil and solids)

 

0-100 ppm Oil and 0-200 ppm solids in any ratio

Accuracy:

 

Oil content reading:

Better than ±5 ppm or ±20 % (whichever is greater)

Solids content reading:

Better than ±5 ppm or ±20 % (whichever is greater)

Calibration

 

Factory set, calibration against specific oil and/or solid is possible.

Zero Setting

 

Factory adjusted zero drift: 1ppm (oil), 3ppm (solid), 5 FTU (turbiditiy) maximum (automatic cell cleaning)

Cell Cleaning

 

Automatic cell wiper

Response Time

 

10 sec maximum (for 90% response to step)

Output

 

Voltage or Current

Oil: Voltage: 0 to 5V DC, Current: 0(4) - 20 mA

Solids: Voltage: 0 to 5V DC, Current: 0(4) - 20 mA

Turbidity: Voltage: 0 to 5V DC, Current: 0(4) - 20 mA

Digital Interface

Display

 

LCD-Display, alphanumeric

Optional: Remote LED-Display

Alarm Structure

 

Oil: Two independent set points adjustable over the monitor range with individual delay time

Solids: Two independent set points adjustable over the monitor range with individual delay time

Turbidity: Two independent set points adjustable over the monitor range with individual delay time

Condition-alarm Optional:

Logic-combination of one alarmpoint of the oil-, solid- and turbidity-alarm each achieves

High flexibility in alarm-structure to special conditions specified by the customer

Fault-alarm indicates monitor fault, displayed fault-codes guarantee rapid fault-analysis

Alarm Contacts

 

Potential free single pole changeover contact for each alarmpoint, rating 5A @ 240VAC/300VDC resistive 1.5A @ 240VAC/30VDC inductive
