Most reliable LEVEL TRANSMITTERS are GWR or Guided Wave Radar type transmitters. They have no movable parts and are not wetted by the process fluids under normal operation. Hence have a long life.

On the lower end we have position transducers working on the principles of flotation.

Also magnetostrictive type are common in industries and comes at a lower cost.

We do have a problem in the company that is one PT connected to PlC which is mean 1 out of 1 in PLC system we do have the PAHH is 55 mbar and PALL 8 mbar with a timer of 15 sec for the PAHH the problem started when PAHH goes more than the set point which is 55 it reached up to 71 but due to timer doesn't trip . We force it and we checked everything nothing there . We replaced the transmitter problem still there the reading goes more than the 55 bar the range for transmitte is 0- 60 mbar . So we did loop check , aculaizing valve , wiring all are okay . What the possible causes for this ???
