Description：
Is based on the measured liquid static pressure type fluid shift delivering the principle of static pressure is proportional to the height of the liquid, the piezoresistive effect of diffused silicon or ceramic sensitive element, the static pressure into electrical signal of a device.
introduce
Input type static pressure liquid level transmitter is based on the measured liquid the principle of static pressure is proportional to the height of the liquid, the piezoresistive effect of diffused silicon or ceramic sensitive element, the static pressure into electrical signals.After temperature compensation and the linear correction, converted into a standard 4-20 madc current signal output.Input type static pressure sensor part of the liquid level transmitter can be directly into the liquid, transmitter part available flange or bracket, convenient in installation.
application
Static pressure type USES the German original SENSE pressure sensor component production, mainly used for urban water supply and drainage, water treatment plants, reservoirs, rivers, oceans, oil tank, and oil, chemical, electricity and other departments of level measurement, can be measured medium is water, oil, acid, alkaline and viscous liquid.Instrument output two wire 4 ~ 20 madc standard current signal, with advanced technology, high precision, stable and reliable quality, convenient installation, detection is a kind of process control system in the ideal liquid level meter.

Good stability and high precision
Directly into the measured medium, install and use is very convenient.
Solid state structure, no moving parts, high reliability, long service life from water and oil to high-precision measurements, larger paste viscosity can not be measured medium foam, deposition, the influence of the electric property Wide range of temperature compensation.
With a power supply reverse polarity protection and overload current limit protection.
Bring about a solid structure, no moving parts, high reliability, long service life;
Bring water to the sewage, oil to larger viscosity liquid can be high precision measurement, not influenced by medium blister, deposit;
Bring with multipurpose mounting bracket, installation is convenient to use;
Bring about good anti-interference, lightning-proof ability;
Bring a power reverse polarity protection and overload current limiting protection;
Bring new material is not easy to fatigue wear, vibration and impact resistance, strong overload capacity

Static pressure type level gauge transducer is determined by measuring the liquid level and the static pressure measured in the liquid level.When the sensor part of the liquid level transmitter into the liquid medium, convert the static pressure of the liquid to voltage signal of sensor and the voltage signal after amplification into 4 ~ 20 madc standard current signal output.
Simple structure: there were moving or elastic element, so stay on sex is extremely high, little maintenance.
Convenient installation: the built-in type structure especially shows the characteristics, without any special tools.
Convenient adjustment: the zero and span two potentiometer can be zero within the scope of the liquid level detection effectively any migration or range change, two adjustment each other.
Wide range of USES;Suitable for high temperature and high pressure, strong corrosive medium level measurement.
