Product Description

Veinasa-LD High Precision 4-20mA Dew Point Sensor -60 degree Temperature Measure Transmitter

Product Description

Veinasa-LD dew-point transmitter uses thermosetting polymer polymer sensitive capacitor, rapid response, stable and reliable, measuring range of -60ºC ~ 20ºC, precision full range ±2ºC, this product has automatic calibration zero function, long-term use of stable performance, this polymer dew-point capacitor is after more than 20 years of hard research results, due to the change rate is too low, The signal is difficult to distinguish on the circuit, we conducted a lot of basic research work, and finally mastered the technology to improve the sensitivity of low humidity.
