DPS Filter Clogging Sensor
Continuous monitoring of filter differential pressure is an important method for assessing filtration system performance and detecting increases in filter resistance. A gradual increase in pressure drop can indicate filter loading and that the filter is approaching a condition requiring servicing or replacement.
The ViraSense DPS-MOD-500 is designed for use in HVAC/R systems, cleanrooms, controlled environments, and air handling systems, enabling continuous measurement and monitoring of differential pressure across the filter.
Filter Pressure Drop Monitoring in HVAC and Air Handling Systems
This product is suitable for monitoring differential pressure across various stages of air filtration, including pre-filters, fine filters, F7/F9 filters, and HEPA filters. It can also be used to monitor the pressure drop of supply and return air filters and assess filter conditions in Air Handling Units (AHUs).
Continuous measurement of differential pressure makes it possible to detect increasing filter resistance and gradual clogging, allowing operators to determine the appropriate time for filter cleaning, servicing, or replacement.
Display and Communication with Monitoring Systems
The DPS-MOD-500 features a 2.8-inch TFT LCD display with a resolution of 320 × 240 pixels, allowing measured data to be viewed directly on the device.
Communication is established via RS485 / MODBUS RTU. The data transmission rate can be configured from 9,600 to 115,200 BPS, while the device address can be set within the range of 1 to 128. This capability enables integration with BMS/EMS systems and the use of differential pressure data in centralized monitoring systems.
Filter Monitoring in Sensitive and Controlled Environments
The ViraSense DPS-MOD-500 can be used in cleanrooms and controlled environments to monitor filter conditions. Monitoring the pressure drop across HEPA filters in pharmaceutical and healthcare facilities is another application of this product.
With an IP54 protection rating, ABS housing, and flush-mounted installation capability, the product is suitable for use in various technical and controlled environments.
