Operating voltage of an Emerson 3051 wireless transmitter

Q&A Wireless

Does anyone know the required operating voltage of a 3051 wireless transmitter? It appears that the product literature makes no mention of it.

Expert’s answer: Operating voltage of an Emerson 3051 wireless transmitter

Hmmm, it’s odd that the product literature doesn’t mention the operating voltage of an Emerson 3051 wireless transmitter. Well, the nominal voltage for the 3051S is 7.2 VDC, where the transmitter uses the 701PBK module. It has a diagnostic to verify the battery level. Yellow warns you that you need to replace the power module soon. The warning occurs below 6.0 volts, and the device will stop measuring below 5.2. The 3051 (no S) model uses a 701GN, and the nominal voltage is 3.6, the warning 3.25, and the failure 2.45.

Rosemount 3051S installation
We have a Rosemount 3051S, air temperature of 400 degrees Celsius, and 3/8-inch stainless steel tubing. Right now we have the device exposed to temperatures around 100 degrees Celsius. We’d like to lower that number, and for that, we need to move the device away from the process. How far out can we go?

Emerson 5300 GWR vs. sludge!
We have an Emerson 5300 GWR LT! Sometimes, the level fluctuates severely. After we open and inspect the chamber, we find the rod clean but sludge in the chamber drain. After flushing the chamber, the level goes back to normal. How does this sludge cause this problem when the rod itself is clean? Can we use the GWR with sludge?

Wireless radar

I have a new level measurement application, and the vendor wants to sell me wireless stuff with the radar. What kind of concerns should I have?
