Founded in 1952, Japanese company Midori Precision is a manufacturer of position sensing solutions for the aerospace, automotive, construction, marine, off-road machinery, manufacturing automation and medical equipment industries.
Green Pot
In 1969, Midori acquired a conductive plastic resistor technology which was ideally suited for precision potentiometer applications. Its Green Pot potentiometer range uses this material and multifinger wiper contacts. Green Pots are servo type pots widely used in industry where wire wounds are not accurate enough and where inductive devices are too expensive. Their resolution is almost infinite. The ultra smooth plastic conductive element contributes to very low electrical noise and uniform torque and friction. These devices have an operating life of more than 10 million cycles.
Precision potentiometers from Midori are available in rotary and linear designs
Typical applications for the rotary pots are on dancer arms and injection moulding machines. The linear pots, available from 10 mm through to 1 m are used on applications like hydraulic cylinder monitoring, active suspension sensing and roller gap control.
Blue Pot
This range of contactless pots employs a pair of magneto resistive Hall Effect elements and permanent magnet to achieve highly stable and noiseless operation requiring very low torque with an almost infinite life span if used correctly. Blue Pots are typically used for high-speed applications or where dust prohibits the use of Green Pots.
The Blue Pot offers infinite resolution, low actuating force, fast response and high frequency response (up to 10 GHz).
Above all, its unique design and construction make the Blue Pot a cost effective, ultra-reliable position sensor since it has no electrical contacts to oxidise or wear-out and is relatively insensitive to environmental factors such as humidity, salt spray, shock and vibration.
The Blue Pot is also available as a linear position sensor and inclination sensor.
Inclinometers
Midori’s inclinometers, which are also contactless, range from small low cost inclinometers to heavy-duty dual-axis units with a 4–20 mA output. These units are widely used by local industry and can be found on anything from wheel alignment machines to draglines. Other applications are automatic platform levelling, crane tip-over protection and pitch and roll monitoring in marine applications.

Other technologies
The majority of organisations implementing oil analysis face the challenge of maximising operational cost savings against the pressure to achieve full production and enhance shareholder value. An organisation may, or may not, achieve the intended benefits for several reasons, chief among them being the failure to implement a sound corrective-action strategy.

To use AI responsibly and effectively, you need at least a basic understanding of how they work and where they can fail. Generative AI then becomes a powerful assistant; without it, you are effectively ‘prompting and praying’, exposing yourself to errors and professional embarrassment.
