Air Pressure Sensor Solutions for Seed Planters – Efficient and Accurate from DwyerOmega

1. Air Pressure Sensors – The Heart of Modern Seed Planters

Since the 1950s, pneumatic air seeders/planters have become one of the most efficient and reliable technologies in agriculture. The operating principle involves using a high-power fan to create a vacuum in the central distribution chamber. Seeds and fertilizers are then drawn by the airflow through tubes and directed to the planting location.

For stable operation and uniform distribution, monitoring and controlling air pressure is mandatory. At this point, pressure sensors, differential pressure switches, and gages from DwyerOmega play a crucial role.

Magnehelic® Gage Series 2000 – Intuitive Visual Observation Recommended models: 2000-60PA, 2000-300MM

• Used to monitor the suction air pressure of the fan system and seed tubes.

• Easy-to-read analog display, no power required.

Differential Pressure Switch ADPS-08-2-N-C – High Pressure Control

• Measuring range up to 2000 Pa, ideal for monitoring strong fan pressure.

• Helps detect blockages, fan damage, or pressure exceeding thresholds.

• Easy to integrate with relay systems, alarms, or PLCs.

Pressure Transmitter Series 629C Typical model: 629C-05-CH-P2-E5-S1

• 4–20 mA signal for accurate and continuous monitoring of air pressure in the system.

• 316L stainless steel material, resistant to harsh environments such as dust and humidity.

Air Velocity Transmitter IEF-SN-10 / IEF-LN-10

• Monitors the velocity of seed suction airflow.

• Helps adjust fan speed to suit different seed types.

Temperature & Humidity Transmitter RHP-3N44-LCD

• Controls air temperature and humidity in the storage chamber and tubes.

• Protects seed quality when operating in hot and dry conditions.

3. Equipment Protection and Optimization

Pressure measurement and monitoring helps:

• Early detection of blockages, protecting fans and pipelines.

• Ensuring uniform seed distribution rate per row.

• Supports preventive maintenance – minimizing machine downtime.

Additionally, products such as:

• Pressure Switch ADPS-03-2-N-C / ADPS-05-2-N-C

• Differential Pressure Sensor 629HLP-06-P2-S1

• Flow Switch WFS-1001-H

also play important roles in auxiliary systems such as cooling fan temperature control, dust filter differential pressure monitoring, and cooling water flow inspection.
