XT650 XT650 input type level transmitter input type level sensor is a measure of the level of pressure sensors, based on the hydrostatic liquid height measured proportional principle, the use of isolated diffused silicon sensor or ceramic capacitors pressure-sensitive sensor, the static pressure is converted to an electrical signal, and then after temperature compensation and linearity correction, converted into a standard electrical signal, usually used in petrochemical, metallurgical, power, pharmaceuticals, water supply and drainage, environmental protection systems, and a variety of media industries level measurement. XT650 input type level transmitter is based on the principle of hydrostatic and proportional to the height of the liquid measured, using the piezoresistive effect diffused silicon or ceramic sensing element, the static pressure turn into electrical signals. After temperature compensation and linearity correction. 4-20mADC convert standard current signal output. Sensor input type level transmitter section can be put directly into the liquid part of the available transmitter flange or bracket, installation extremely easy to use. Chinese name input type level transmitter range 0-100 m English name Input type level transmitter LCD display applications in petrochemical manufacture light weight spinning metallurgical treatment 2KG electricity output 4-20mA communications protocol hart Housing Material Aluminum 24VDC power supply One. Features good stability, high precision liquid level transmitter input directly into the measured medium, very easy to install and use. Solid-state structure, no moving parts, high reliability, long life from the water, the viscosity of the oil to the paste can be carried out with high precision measurements, not measured media bubble, deposition, the electrical characteristics of a wide range of temperature compensation. Input type level transmitter with power reverse polarity protection and overload current limit protection. II. Works with static pressure measurement principle: When the input type level transmitter into the liquid to be measured at a certain depth, the pressure on the liquid level sensor welcome formula: Ρ = ρ .gH + Po where: P: Variable Towards level transmitter pressure on ρ: Measuring liquid density g: local acceleration of gravity Po: the surface atmospheric H: transmitter into the depth of the liquid at the same time, through the guide gas stainless steel pressure liquid is introduced into the positive pressure sensors chamber, the atmospheric pressure Po and then the liquid level sensor on the negative pressure chamber is connected to the back of the sensor offset Po, the pressure is measured by the sensor: ρ .gH, obviously, by taking the measured pressure P, the liquid level depth can be obtained three . The main technical indicators measuring range: 0.3 ~ 110m Accuracy: 0.2,0.5,1.0 Operating Temperature: -20 ~ 80 ℃ Output signal: 4 ~ 20mADC wire Supply voltage: standard 24VDC (12 ~ 36VDC) dead zone: ≤ ± 1.0 % FS Load capacity: 0-600Ω Relative humidity: ≤85% protection: IP68 proof mark: ExiaⅡCT4-7
