The advantage of the liquid level sensor is introduced

Liquid level sensor is also can be widely used in liquid level measurement, because of its principle and characteristics of the change of liquid level sensor of material level parameters can be converted into a standard current signal, remote transmission to the operating room, for secondary instrument or computer for centralized display, alarm and automatic control, and its good structure and installation method. Can be used in high temperature and high pressure, strong corrosion, easy to crystallization, prevent jams, prevent cold junction and under special conditions, such as solid powder, granular material level, material level or the level of continuous testing, which can be widely applied in all kinds of industrial process control testing.

a, craft: diffusion silicon, ceramic capacitors, sapphire capacitance optional

split type, one-piece optional, range: 0 - - - 05 - - - 4 -. 200 meters, output - - 20mA( 2 wire system) Power supply: 10 - - - 36 VDC input type static pressure liquid level meter and reliable anti-corrosion with ceramic probe measurement unit, liquid level sensor is used for water purification, sewage and salt water level measurement.

the 1, not blocked airway, airway cannot fill the

3, do not use sharp things to bad diaphragm

4, but using short-circuit

5, 6, using the full range of below 60%, the effect is best, the longest service life

2, liquid level sensor features:

1, intelligent signal processing technology, high precision, good stability, strong anti-jamming performance.

2, full, long-term stability of zero to 01% FS years, within the scope of the compensation temperature 0 ~ 70 ℃, the temperature drift less than 01% FS, throughout the allowed working temperature range is less than 03% FS.

3, solid structure, no moving parts, high reliability, long service life, has the reverse protection, current limiting protection circuit, when the installation is negative answer the reverse will not damage the transmitter

4, easy installation, simple structure, economy is durable.

5, liquid level sensor is suitable for network acquisition of multipoint pressure parameters and bus supports 255 devices, can have at the same time: 4 - 20 ma output and RS485 communication function, the output current resolution is better than 3 ua.
