How do I set upper range value and lower range value on a Siemens pressure transmitter?

A customer needed to re-range a Siemens SITRANS P DS III transmitter without applying pressure. He’d read my earlier blog post about using the pushbuttons to program the DS III (Pressure Transmitter Pushbuttons to the Rescue!), and where to find the Z-fold instruction sheet.

All was going to plan, until he started looking for the settings for lower range value (LRV) and upper range value (URV). And then, in an all-too-familiar scenario, he hit a roadblock. The instructions don’t actually mention URV and LRV, the terms he’s familiar with, by name or acronym. So what’s a guy to do?

Radar vs Ultrasonic Level Calibration Points (The Devil’s in the Details)

People who have used Milltronics or Siemens ultrasonic continuous level measurement systems are used to the way configuration is done.  It’s not uncommon that when they start up their first Siemens radar transmitter they encounter a stumbling block – the 4-20mA output doesn’t respond correctly. 

The radar will start up and run, and if the tank level is low, they’ll get a valid level reading on the transmitter’s display, but the 4-20mA will be incorrect (too high a percentage).  Or, if the tank level is at a medium or high level, both the indicated level in the display and the output will be maxed out at 20mA.   It’s a misunderstanding about where the span measurement starts from.

Pressure transmitter pushbuttons to the rescue!

I took a call the other day from a contractor. He was at the construction site, on deadline, and frantic. He was trying to set the zero and range on a Siemens SITRANS P DS-III pressure transmitter‘s 4-20 mA output. He had a HART handheld communicator, but no device descriptor file (DD) that made the two talk to each other. 

Could I help?  Sure! I just asked, “Do you have a Phillips screwdriver?”

Newly revised Honeywell stripchart manual has navigation overviews

While talking with people in an instrument shop last week, a technician popped in with a question on settings for a Honeywell paper strip chart recorder, the DPR 250.  I always have to look up the keypad navigation paths because I can’t remember them.  Read the rest of this entry »

My Siemens infrared handheld programmer is missing. What do I do?

Looking for a programmer for your radar level unit, and can only find the ultrasonic version? Need the ultrasonic, but it’s disappeared? Not to worry: You can use either Siemens/Milltronics handheld programmer in a pinch!

Those Siemens handheld programmers are the same size and sorta look alike until you look closely.  One is for radar, the other for ultrasonics.  What if you can only locate the Wrong OneRead the rest of this entry »

Save your custom configuration! Avoid the headaches!

Do you need to send an instrument to the factory for repair or service? Before you disconnect it, pack it up, and ship it out, be sure you do the following:

  1. Make a backup or copy of your instrument configuration, so you can quickly reinstate the settings.
  2. Make sure you have a written record of your settings on file. Several manufacturers include a configuration worksheet in the instrument user manual. If it’s not there, you can write them on a copy of the quick-start or setup installation guide.

Why is this critical?
