Summary
LHDG700 series inductance liquid level transmitter is a new type of liquid level measuring instrument developed by our factory. It can change the material level, the medium level parameters into standard current signal and sent to the control room, for two meter or computer system of display, alarm or automatic control. The good structure and installation, can be applied to high temperature and high pressure, strong corrosion, easy crystallization, anti blocking, anti cold and solid powdery and granular materials under the special circumstances of the liquid level, the level of continuous measurement, level measurement is widely used in electric power, metallurgy, chemical, food, pharmaceutical etc. industry and sewage treatment, boiler, coal bag and other places.
Characteristic
It has the advantages of compact structure, small volume, simple installation and maintenance, uniform size.
* many signal output form, convenient for different system configuration.
* Teflon probe, acid, alkali and other strong corrosive liquids and high temperature.
The measurement part. In liquid, only a PTFE or PTFE wire rod as the sensing probe, high reliability.
* full sealed Aluminum Alloy shell and stainless steel fasteners.
* on the high temperature pressure vessel and measuring atmospheric model and measurements from the measured temperature of the liquid, the proportion and the shape of the container and pressure.
By measuring output ends and measuring output, power supply three end isolator multiple circuit structure, with isolator, adapt to different signal grounding way.
* perfect overcurrent and overvoltage protection and power supply polarity protection.
Main technical index
Measuring range: 0.2-20 meters.
* precision class: 0.2, level 0.5, level 1
* probe temperature: -40 ~ +250 C
This allows the container pressure: -0.1MPa ~ 2.5MPa
By the measurement of dielectric conductivity is not lower than the acid and alkali, water and other non conducting liquid crystalline 10-3 s/m
* power supply: DC12-35V (isolated DC21-27V)
* working current: (output 20mA) non isolated line, three line: 20mA
It ends three wire isolation: "32mA; three terminal four line: 35mA
* output: 4-20mA (0-10mA, 0-20mA)
Output protection: 27mA.
Voltage isolation between * measurement, output power: 1000V
This range adjustment range and zero migration: ≥ ± 30%FS
This transmitter body size: 6× 85?
