ViraSense: A Precise Solution for Differential Pressure Monitoring

The ViraSense DPT-MOD-125 is designed to measure and monitor differential pressure in ventilation systems, air handling units, and controlled environments. Differential pressure is an important parameter for monitoring ventilation system performance and controlling pressure conditions between different spaces. Continuous measurement can provide the information needed to assess system status.

Differential Pressure Sensor

The DPT-MOD-125, with a measurement range of ±125 Pa and an accuracy of ±2 Pa, enables differential pressure monitoring across various systems. This capability is suitable for applications such as checking pressure differences between adjacent rooms, monitoring pressure in ducts and ventilation systems, and assessing the operating conditions of fans, blowers, and filters.

Air Pressure and Flow Monitoring in HVAC Systems

This device is suitable for use in HVAC/R systems and air-handling systems. It can be used in applications involving the monitoring of fans, blowers, filters, and air pressure conditions. Measuring air pressure and airflow inside ducts (In-Duct) and in Variable Air Volume (VAV) systems is also among its applications.

Differential Pressure Monitoring in Cleanrooms

In cleanrooms and controlled environments, pressure differences between adjacent spaces are particularly important. The DPT-MOD-125 is designed to monitor differential pressure conditions in these environments, enabling continuous monitoring of air pressure in cleanroom applications.

This capability can be used to monitor pressure differences between adjacent rooms and assess pressure conditions in ventilation and clean air distribution systems.

Display and Communication with Monitoring Systems

The DPT-MOD-125 is equipped with a 3.2-inch TFT LCD display with a resolution of 240 × 320 pixels. The display supports 65,000 colors and presents measured data to the user.

For communication with monitoring systems, the device supports RS485 with the MODBUS RTU protocol. Its data transmission rate is adjustable from 9,600 to 115,200 bits per second. Addresses can also be configured within the range of 1 to 128.

Design for Facility and Controlled Environments

The device features an ABS housing with a matte white finish and an IP54 protection rating. It is designed for flush-mounted installation, allowing it to sit level with the mounting panel.

The DPT-MOD-125 operates within an ambient temperature range of +2°C to +45°C. With a housing size of 100 × 110 mm and a front panel measuring 130 × 120 mm, it is designed for installation at designated pressure monitoring points within a system.
