Product details
MP-406CSoil moisture sensor (current output type)
Produced by Zhongtian Instrument‘MP-406CSoil moisture sensor 'is a prototype‘MP-406B’The derivative type integrates a voltage current conversion module internally, realizing the measurement of signals4 – 20 mA(or0 – 20 mA）Current loop output, meeting the requirements for long-distance signal transmission in specific application scenarios.
In addition to signal output forms‘MP-406CTechnical parameters of soil moisture sensor‘MP-406B’Completely identical, it is mainly used to measure the volumetric moisture content in soil or other media. After on-site calibration, its accuracy can reach±1%Within.
‘MP-406CThe soil moisture sensor adopts advanced voltage current conversionICConvert the original DC voltage signal into a current output, and the dynamic range of the output can be set according to the user's needs4 – 20 mAperhaps 0 – 20 mAZhongtian Instrument provides corresponding 'output current~medium volume moisture'%’Convert expressions.
‘MP-406CThe soil moisture sensor has good temperature stability characteristics and a wide working temperature range, and can be installed in harsh environments that other products cannot adapt to. Changes in soil electrical conductivityMP-406BThe impact is limited, so it can be directly installed in saline alkali soil‘MP-406CSoil moisture sensors have wide applications in fields such as agriculture, forestry, environment, and ecology.
‘MP-406CStandard configuration of soil moisture sensor5riceThe length of the connecting wire can be adjusted according to customer requirements during sales. The current output sensor can reach up to 100 meters under normal conditions. Please consult Zhongtian Instrument or authorized sales representatives for detailed information.
