Soil moisture sensor analog 4-20mA

NBL-S-THR Soil Moisture Sensor (analog 4-20mA output) - Ideal for precise soil environment monitoring 

NBL-S-THR Soil Temperature and Moisture Sensor Product Overview:

The NBL-S-THR Soil Temperature and Humidity Sensor is a soil moisture and temperature measurement instrument that combines high accuracy and sensitivity. By transmitting electromagnetic wave pulses, the sensor is able to quickly measure the apparent dielectric constant of the soil, and then accurately calculate the true moisture content of the soil. At the same time, the sensor can also measure soil temperature, providing reliable data support for soil moisture monitoring, water-saving irrigation, greenhouses, grass pastures and soil rapid measurement. 

 NBL-S-THR Soil Temperature and Moisture Sensor Technical Parameters:

Current type (3-wire 4～20mA output) Calculation method:

Soil humidity RH = (I-4)/16 × 100%

Soil temperature T=(I-4)/16×150-50

- Wide measuring range, excellent adaptability: from -50℃ to 100℃ temperature, 0% to 100% RH humidity, NBL-S-THR soil temperature and humidity sensor can comfortably cope with, to ensure the accuracy of the data, is the ideal choice for greenhouse, farmland, pasture management.

- Three-wire 4-20mA output, simple integration: Unique current output design, no need for complex conversion, directly interface with PLC or DCS system, simplifying the signal processing process, reducing the complexity of system integration, and realizing remote monitoring and automation control.

- High precision, low power consumption, long-lasting operation: ±3% humidity accuracy and ±0.5℃ temperature accuracy, ensuring that every measurement is accurate and reliable. The power consumption is as low as 0.3W, which can maintain efficient operation and reduce maintenance cost even in long-term field deployment.

- IP68 protection, no fear of harsh environments: Whether it's a stormy day or high desert temperature, the top protection level of IP68 ensures that the sensor works stably under extreme conditions and can be buried for a long period of time without worrying about corrosion or flooding.

- Easy to install, scientific measurement: Provide both rapid and buried measurement methods, whether it is a temporary rapid assessment or long-term continuous monitoring, can be easily accomplished.

 NBL-S-THR soil temperature and humidity sensor installation and measurement:

 Quick measurement method

1. Select a suitable measurement site, avoiding hard objects such as stones.

2. Plan the top layer of soil, keeping the original looseness of the soil underneath.

3. Insert the sensor vertically, ensuring close contact with the soil.

4. Take several measurements to find the average value to improve the accuracy of the measurement.

 Buried Measurement Method

1. Vertically dig a pit with a diameter of more than 20 cm according to the required depth. 

2. Insert the sensor pin horizontally into the wall of the pit and fill the pit with compaction. 

3. After stabilizing for a period of time, measurements and recordings can be made for several days, months or even longer.

 Precautions for installing the soil sensor

- When measuring on hard ground, drill a hole before inserting the sensor.

- The sensor should be protected from severe vibration and shock, and avoid hitting it with hard objects.

- When using in strong sunlight, please pay attention to shading and protection to prevent excessive temperature from affecting the sensor.

 Soil temperature and moisture sensor application areas
