American deep special LPDT dew point transmitter
American SHENTE LPDT dew point transmitter is provided by Beijing huituo Information Technology Co
, Ltd
Two wire integrated on-line dew point transmitter of SHENTE company (dew point meter) can quickly and accurately measure the humidity and dew point of dry air, petrochemical gas, natural gas, compressed gas, generator cooling hydrogen, transformer and high-voltage switch insulation gas, welding gas and oxygen for ship and aviation within the range of - 100 ℃ ~ + 20 ℃
LPDT two-wire integrated online dew point transmitter can be displayed on site at the range of - 100 ℃ ~ + 20 ℃ Measure the humidity and dew point of dry air or other gases quickly and accurately

Application fields of American deep special LPDT dew point transmitter: including petrochemical, natural gas, dry gas and compressed gas, generator cooling hydrogen, transformer and high-voltage switch insulation gas, welding gas and oxygen for ship and aviation Principle and structure: the inner core is a high-purity aluminum rod, the surface is oxidized into alumina film, and it is coated with a layer of porous gold film
A capacitance is formed between the gold film and the inner core
Due to the water absorption characteristics of alumina film, when water vapor molecules are sucked into it, the capacitance value changes
The humidity can be obtained by detecting and amplifying the capacitance signal Technical indicators: Principle: ultra thin alumina capacitor range: - 100 ℃ ~ + 20 ℃, accuracy: & plusmn; 3 ℃ repeatability: & plusmn; 0
5℃  Temperature range: - 10 ～ + 70 ℃ sampling flow rate: static to 100 m / s storage temperature: - 40 ～ + 80 ℃ display: three and a half digit LCD control with backlight: three keys to realize function control calibration method: automatic calibration (providing saturated moisture above + 20 ℃) output: 4 ~ 20mA analog signal , Temperature measurement: the instrument can simultaneously measure the temperature of the gas sample passing through the sensor
Pressure sensors can also be installed as required
Mechanical properties: shell: stainless steel, working pressure: standard within 34bar, optional within 340bar, mechanical connection: 14mm & times; 1
25mm and 3 / 4 & rdquo& times; 16 threaded electrical connection: 2
