I. Overview: 

 ZLB master control transmitter consists of permanent magnets, magnetostrictive displacement transmitter, magnetic memory switches, protection casing, a permanent magnet as the measuring element, the use of magnetic coupling principle, monitoring of hydropower turbine generator group guide water bodies or the stroke of the needle, its on-site mechanical instructions to turn the magnetic column, with four (according to user requirements more) configuration instructions guide vane position of the magnetic memory switch, the electrical output corresponding to the measured stroke Analog 4 to 20mA and four relay switch. 

 Second, characteristics: 

 ? A displacement transmitter high precision, zero drift and good stability. 
 ? Displacement transmitter field LED display displacement values, in addition to 4 ~ 20mA analog, while the four relay outputs. 
 ?, Magnetic memory switches with moving parts, no mechanical contact its installation does not occur in fixed operating position drift. 
 ? 4, the whole stainless steel materials, moisture resistant. 
 Third, the technical parameters: 
 Simple structure, complete functions, easy to install. 
 ? Range: 100 ~ 1500mm 

 ? Power supply: 24VDC
