Input type liquid level of the thermocouple sensor principle and application

Input type level thermocouple sensor is a kind of commonly used liquid level measuring instrument, based on the measured liquid static pressure and the liquid height is proportional to the principle of measurement, is widely used in petroleum, chemical industry, metallurgy, electric power, water supply and drainage, environmental protection and other fields. Engineering today is to introduce the specific investment type level thermocouple sensor, hope you can help to you.

input type level working principle of the thermocouple sensor

when the liquid level transmitter into the liquid to be tested in a certain depth, thermocouple sensor to meet the pressure on liquid surface formula is: Ρ = rho. g。 H + Po

type:

P: transmitter into liquid level pressure

rho: the measured liquid density

g: local acceleration of gravity

Po: liquid surface atmosphere

H: transmitter into the depth of the liquid

at the same time, through the gas leading stainless steel pressure of liquid is introduced into the positive pressure cavity of thermocouple sensor, atmospheric pressure on the surface of the liquid Po again connected to the negative pressure cavity of thermocouple sensor, to offset the thermocouple sensor on the back of the Po, for the thermocouple sensor measured pressure: rho. g。 H, apparently, by measured pressure P, can get the depth of the liquid level.

type liquid level of the thermocouple sensor application

input type level thermocouple sensors ( Static pressure level thermocouple sensor thermocouple transfeeder water thermocouple sensor) Thermocouple sensor is a kind of measuring liquid level pressure.

input type level thermocouple sensors ( Thermocouple) Is based on the measured hydrostatic principle of proportional to the height of the liquid, USES the overseas advanced isolation diffusion silicon pressure sensitive element or ceramic capacitance sensitive thermocouple sensor, the static pressure is converted to electrical signals, after temperature compensation and the linear correction, converted into a standard electrical signals ( Is commonly 4 ~ 20 ma1 ~ 5 VDC) 。

input type level thermocouple sensors ( Thermocouple) Applicable to petrochemical industry, metallurgy, electric power, pharmaceutical, water supply and drainage, environmental protection system and industry such as all kinds of medium level measurement. Exquisite structure, simple adjustment and flexible installation convenience is provided for the user to easily use. The user can choose according to need 4 ~ 20 ma, 0 ~ 5 v, 0 ~ 10 ma, such as standard signal output.
