Description
The wall-mounted/embedded micro differential pressure transmitter is suitable for positive pressure, negative pressure or differential pressure gas pressure measurement of various ventilation and air-conditioning systems and equipment, with relay switch control and sound and light alarm. Both wall-mounted and embedded installation are possible. In addition, we can also provide customized products that meet the application needs of customers. If needed, please feel free to contact us.
Features
- Micro differential pressure transmitter has the default configuration where the low-pressure side is connected to the front panel and the high-pressure side to the side panel. For other requirements, please contact us.
- It has a built-in buzzer that provides both audible and visual alarms, with the ability to set the alarm pressure range on-site.
- The micro differential pressure transmitter uses imported components, offering low temperature drift and high stability to ensure long-term, reliable operation.
- The transmitter supports both wall-mounted and embedded installations, meeting the needs of various on-site applications.
- Its housing is made of flame-retardant ABS material, offering excellent impact resistance, heat resistance, and other outstanding properties.
