Written by: Dan Weise

The venerable Siemens Milltronics line of level controllers, the MultiRanger and HydroRanger Series, recently received a major update. The new models have high resolution LCD displays and built-in configuration tools with English language menus. Configuration time is reduced significantly without the need to reference manuals for parameter codes. These updated models have ‘HMI’ in the model name: MultiRanger HMI or HydroRanger HMI.

Regulators 101: Pressure vs. Back Pressure

Let’s start with the basics.

What is a pressure regulator?How a Pressure Regulator Works

A pressure regulator is a normally-open valve used to regulate or reduce undesirable, high upstream pressure. The pressure regulator must be installed at the START of a system, before any pressure-sensitive equipment.

The valve is held open by springs, and a screw that sets spring force. When outlet pressure exceeds the setpoint, the valve will close. When the valve closes, pressure is reduced downstream.

Belt Scales 101: Webinar Recap

In case you missed last week’s webinar on belt scales, we’ve put together some of the key points:

Conveyor Considerations: Use strings to align the scale with the idlers on each side of the weigh bridge.Idler.png

  • Each idler should be parallel to the idler next to it.
  • The center of each idler should be in line with the idler next to it.
  • Each idler should not be higher or lower than the idler next to it.
  • Minimum of 2, preferred 3, idlers on each side of the weigh bridge

Free Download: Siemens e-book Going the Distance – Solid Level Measurement with Radar

Written by: Dan Weise

A couple years ago, Siemens published a great handbook on using radar to measure solids levels, but the $60 price tag limited its readership.

You can now download the book for free as an electronic epub file formatted for electronic readers, which in my case, is the Firefox browser on my laptop.  It could be any browser (Internet Explorer or Chrome), or presumably any electronic book reader.
