LMT200 external mount magnetostrictive level transmitter - 3

— Principle of operation: The LMT200 is based upon the magnetostrictive principle. 1 1 The device electronics generates a low energy current pulse at fixed intervals. 2 The electrical pulses create a magnetic field which 2 travels down a specialized wire inside the sensor tube. 3 3 The interaction of the magnetic field around the wire and the magnetic float causes a torsional stress wave to be induced in the wire. This torsion propagates along the wire at a known velocity, from the position of the magnetic float and toward both ends of the wire. 4 4 A patented sensing element placed in the...

— ...Probe selection guide Probe selection chart - standard 85 (185) Directions: 1. determine the maximum ambient tempearture and the maximum process temperature of the installation. 2. Plot the intersection between the two temperatures on the chart. 3. Choose the appropiate probe by matching the zone number with the probe type. *Ambient temperature is the air temperature in the work area surrounding the device. It takes into account the influence of heat created by equipment surrounding the area personnel will be working. It is not the skin temperature of the chamber or insulation blanket....
