PTFE anti-corrosion type liquid level transmitter, all the wetted parts are made of PTFE material, have characters of high temperature resistance, corrosion resistance and anti clogging. And it is widely used in any liquid level measurement of atmospheric pressure (except for material corrode PTFE).
1. Characteristics
Ø Good stability, high precision, high temperature resistant, corrosion resistant, anti clogging.
Ø Directly input to the measured medium, installation and usage are very convenient.
Ø Compact structure, no moving parts, high reliability, long service life.
Ø It is widely used in any liquid level measurement (except for material corrode PTFE).
Ø Can measure from the water, oil, acid, alkali, salt to larger paste viscosity fluid with high precision measurement, and are affected by foaming of the measured medium, deposition, the influence of the electric property.
Ø Have reverse polarity power supply and overload current protection function.
2. Technical Parameters
Ø Measuring range: 0 ~ 30 meters.
Ø Output signal: 4 ~ 20 mA/DC.
Ø Power supply: 24V+- 5 VDC.
Ø Accurate rating: 0.5%FS.
Ø Long term stability: Plus or minus 0.2% FS/year
Ø Medium temperature: - 50 ~ 100º C( state of not clotting)
Ø High temperature type: -50~200~300º C( state of not clotting)
