Bi-directional low range 4 to 20 milliamp differential pressure transmitter covering an air pressure range from -100 to +100 pascals, for use in cleanrooms, isolation rooms, and filter monitoring.
The DPS differential air pressure transmitter is designed for ultra-low air pressure measurement applications requiring high precision and a bidirectional range. With a measurement capability spanning from -100 to +100 Pascals, this transmitter is ideal for monitoring the delicate pressure balances crucial in environments such as cleanrooms, isolation rooms, and filter monitoring systems. The bi-directional capability means the DPS can accurately measure both positive and negative pressure differentials, providing a complete picture of pressure fluctuations. This is particularly important in applications where maintaining a specific pressure regime is critical for safety or product integrity.
The 4-20mA output signal allows for easy integration with standard industrial control systems, enabling remote monitoring and process automation. The inclusion of an LCD display provides local indication of the pressure reading, simplifying on-site checks and troubleshooting. Furthermore, the availability of bi-directional scaling as a special option enhances the versatility of the DPS series, allowing it to be tailored to specific application requirements. This customization option ensures optimal performance and integration into diverse systems. The DPS employs a 6.6 x 11 tube for process connection, a standard size that ensures compatibility with common fittings and tubing infrastructure. This simplifies installation and minimizes the need for specialized adaptors.
Typical Applications:
- Cleanroom Monitoring: Maintaining a consistent positive pressure in cleanrooms prevents contaminants from entering the controlled environment. The DPS series can precisely monitor the pressure differential between the cleanroom and surrounding areas, ensuring adherence to stringent cleanliness standards.
- Filter Status Indication: By monitoring the pressure drop across a filter, the DPS series can provide an early indication of filter clogging. This allows for timely filter replacement, preventing system performance degradation and potential contamination.
- HVAC Balancing: In ventilation systems, the DPS series can be used to balance airflow between different zones, ensuring optimal air distribution and occupant comfort.
- Flow Measurement: When combined with a flow element such as an orifice plate, the DPS series can be used to infer flow rates in low-pressure air systems. This is useful in applications such as leak detection or monitoring airflow in pneumatic systems.
