SZY-136P liquid level transmitter selects pressure transmitter as the pressure measuring component. The liquid level pressure signal is collected by the collector and transmitted to the pressure transmitter, which converts the pressure signal into liquid level signal output.
The relationship between the pressure transmitter and the liquid level is: P=0.0098ρH+Pc
Where: P pressure MPa; ρ liquid density (g/cm3); H liquid surface depth (m); Pc liquid surface pressure (atmospheric pressure for 0)
Main Features:
- The sensor does not touch the measured medium, high reliability
- Unique conversion circuit, stable performance
- Overvoltage reverse polarity protection
- Zero fullness field adjustable
- Good stability, better than 0.2% FS/year
