LD-500 type dew point instrument
One, overview
LD-500 type dew point instrument of imported impedance type humidity sensor, has the advantages of fast reaction rate, stable performance, corrosion resistance. Anti condensation from the new calibration technology. For a variety of industrial processes have strict control of occasions to the moisture content.
Two, the main use of
• compressed gas, natural gas, chemical raw material gas
• plastic drying equipment
Gas, generating hydrogen cooling gas high voltage insulation, power system
• drying industry
• other strict process control for trace water
Three.
• import impedance type humidity sensor
• large screen LCD display, Chinese menu function selection
Signal transmitters, with a new type of microprocessor, the operation is very convenient
• dew point temperature and water ppm value display, no table lookup calculation
• automatic data storage, paperless recorder with function
• measuring point alarm set
• communication port RS232
Four, the main technical indexes:
• measurement range: -90 ℃ ~+10 ℃, -80 ℃ ~+20 ℃, -60 ℃ ~+40 ℃
• basic error: ± 2 ℃
• repeatability: ± 1 ℃
• temperature: <0.2 ℃ / C
• environment and storage temperature: -40 ℃ ~+50 ℃
• the maximum operating pressure: 10 bar (-90 ℃ ~+10 ℃)
20 bar (other range)
• the sample gas flow: 400ml/min
• linear output: 4 - 20 m A (a maximum load of 750 Ohm)
• calibration period: 12 - 24 months
• dust protection: with a 10 micron filter head protective cover
• supply voltage: 220VAC ± 10%
