2pcs WSP5110 Refrigerant Gas Sensor

[shortdesc]Application:It is widely used in domestic, environmental occasions for Refrigerant detection.Advantage:High sensitivity to Refrigerants,quick response and resume,low power consumption[/shortdesc]Production Description:WSP5110 Refrigerant detection gas sensor adopts multilayer thick film manufacturing technology. The heater and metal oxide semiconductor material on the ceramic substrate of subminiature Al2O3 are fetched out by electrode down-lead, encapsulated in metal socket and cap. Conductivity of the sensor is affected by the concentration of target gas. The higher the concentration is, the higher conductivity of sensor gets. Users can adopt simple circuit to convert variation of conductivity into output signal corresponding to gas concentration.Feature: High sensitivity to Refrigerants quick response and resume low power consumption simple detection circuit good stability and long life Application:It is widely used in domestic, environmental occasions for Refrigerant detection.Technical Parameter: Model WSP5110 Sensor Type Semiconductor flat surfaced sensor Standard Encapsulation Metal Cap Detection Gas Refrigerant, benzene, alcohol &etc. Detection range 10～1000ppm Standard circuit Loop voltage VC ≤24V DC Heating voltage VH 5.0V±0.1V AC or DC Load resistance RL Adjustable sensor features in standard test condition Heating resistance RH 90Ω±10Ω(Room Temperature) Heating consumption PH ≤300mW Surface resistance RS 30KΩ～200KΩ(in 100ppm Refrigerant) Sensitivity S Rs(in air)/Rs(in 100ppm Refrigerant)≥3 Concentration slope α ≤0.65(R200ppm/R50ppm refrigerant) Standard condition of test Temperature, humidity 20℃±2℃；65%±5%RH Standard test circuit Vc:5.0V±0.1V；     VH:5.0V±0.1V Warm-up time Not lessthan120 hours
