Product Introduction
Online-dew-point-transmitter-01
70903002
SKA/WSD-LDY type
Online dew point transmitter
It uses a polymer high-molecular sensitive capacitor, offering rapid response and stable reliability.
Damn, the measurement range is -80℃～20℃ Td, with an accuracy of ±2℃ Td across the full range. This product features automatic zero-point calibration and automatically heats to clean chemical substances attached to the sensor surface, ensuring extremely stable long-term use. This polymer dew point capacitor is the result of over twenty years of arduous research. Typically, polymer capacitors struggle to measure dew points below -40℃ Td due to the extremely low rate of change, making the signal difficult to distinguish in the circuit. Through extensive fundamental research, we have finally mastered the technology to enhance low-humidity sensitivity. Currently, when the dew point changes from -70℃ Td to -50℃ Td, the base capacitance shifts from 300 pF to 305 pF, surpassing all polymer dew point capacitors on the market.
