ADPS-08-2-N-C – Low Pressure Monitoring Solution for Air Filtration Systems
Posted on: 22/08/2025
In industrial and residential air filtration systems, monitoring low differential pressure across filters is critical for maintaining filtration efficiency and stable airflow.
The ADPS-08-2-N-C from Dwyer Instruments (USA) is a mechanical differential pressure switch specifically designed for low-pressure applications. With high sensitivity and durable construction, it's ideal for air filter monitoring tasks.
1. Product Overview
ADPS-08-2-N-C belongs to Dwyer's Adjustable Differential Pressure Switch line, engineered to detect small pressure differences between two measurement points. It uses a flexible diaphragm and adjustable spring mechanism to trigger control or alarm signals when the differential pressure exceeds or falls below the set threshold.
Key Features:
-
Highly sensitive to very low differential pressures – ideal for fine filtration systems
-
Adjustable range directly on the device body
-
No power supply required – durable, low-maintenance mechanical design

2. Key Technical Specifications
-
Pressure Range: 50–800 Pa (adjustable)
-
Maximum Pressure Resistance: 10 kPa
-
Operating Temperature: -20 to 85°C
-
Output Contact: SPDT (5A/250VAC)
-
