LMT100 Magnetostrictive Level Transmitter, High accuracy liquid level and interface level detection.

The LMT Series of level transmitters is a modular range of field mounted, advanced microprocessor-based electronic transmitters, utilizing multiple sensor technologies. Accurate and reliable measurement of liquid level and interface are provided in even the most difficult and hazardous  industrial environments. The LMT100 is also available with optional temperature measurement.

Overview

The LMT100 is based upon the magnetostrictive principle. 

1. The device electronics generates a low energy current 

pulse at fixed intervals. 

2. The electrical pulses create a magnetic field which 

travels down a specialized wire inside the sensor tube. 

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. A patented sensing element placed in the transmitter 

assembly converts the received mechanical torsion 

into an electrical return pulse. 

5. The microprocessor-based electronics measures the 

elapsed time between the start and return pulses 

(Time of Flight) and converts it into a position measure-

ment which is proportional to the level of the float.

LMT100 is preferred for:

• Interface Measurement

• Exceptional performance with emulsion

• Measurement with foam on layers fluid surface

• Hydrocarbons and chemical control
