Temperature Sensor Selection and Placement

Meaningful temperature measurements depend on the selection of the proper sensors and controls and the proper placement of sensors to accurately measure the targeted temperature.  For example, it was previously stated that bimetallic sensors, in most cases, ultimately sense the … Continue reading

More Temperature Sensors – Electrical

Preceding blogs have described a number of mechanical means for measuring temperature based on the expansion and contraction of liquids and solids.  Another major classification of temperature sensors are based on electrical phenomenon. Thermocouples – A thermocouple sensor utilizes a … Continue reading

Temperature Sensors Continued

In the preceding blog we looked at the expansion and contraction of liquids as a means of measuring temperature.  The expansion and contraction of solids (usually metals) is another way to measure temperature. Most solids expand and contract in a … Continue reading

Temperature Sensors

In preceding blogs I have identified temperature as probably the single most important variable in a cleaning process.  Devices that sense and control temperature, therefore, are a critical part of a cleaning system.  Let’s take a quick look at a few … Continue reading

Chemical Concentration – Economic and Process Considerations

I have talked before on the blog about the subject of chemical concentration and its relationship to cleaning.  A couple of recent incidents prompt me to re-address the subject of chemical concentration but from a little different angle. It’s a … Continue reading

Other Oil Removal Options

In some cases, previously described oil removal technologies based on the gravity separation of oil from the cleaning solution are unjustifiably cumbersome and expensive.  Fortunately, smaller scale solutions are available for use in such applications. Oil Skimmers – Oil skimmers … Continue reading

Common Misconceptions About Oil Removal Using Oil Coalescers

Preceding blogs have described oil removal techniques for industrial cleaning in some detail.  It would be nice if this was always a simple consideration - but it is not! The case for using an oil coalescer is pretty clear cut as … Continue reading

Oil Removal and Management – Oil Coalescer

In the blogs Chemistry – Oil Splitting and Oil Emulsification – Part 1 and Chemistry – Oil Splitting and Oil Emulsification – Part 2, I discussed how oils are removed from parts using chemistry that either splits or emulsifies the oil.  … Continue reading

Chemistry – Oil Splitting and Oil Emulsification – Part 1

As I have said before on this blog, I am not a chemist.  Whatever I say about chemistry on the blog is expressed in layman’s terms and is based on practical experience and not on any deep understanding I have … Continue reading

Six Sigma – Monitoring Variables in Cleaning – Part 3 (final)

A few more things to monitor – Dirty rinse – An effective rinse is critical to most cleaning processes.  Only in very limited cases can residues from the cleaning step be left on parts after they are cleaned.  It does … Continue reading
