FAQs of Dwyer DM-2019-LCD PRESSURE TRANSMITTER:

Q: How do I install the Dwyer DM-2019-LCD Pressure Transmitter?

A: The transmitter can be mounted on panels or surfaces using the included mounting screws. Electrical connections are made with easy-to-access screw terminals. Ensure the environment is within the rated temperature range and that you use the correct power supply (12-30 VDC).

Q: What gases can the DM-2019-LCD Pressure Transmitter measure?

A: This device is suitable for measuring the pressure of air or non-corrosive gases only. Using it with aggressive or corrosive gases may damage the sensor and void the warranty.

Q: When should I perform zero adjustment on this transmitter?

A: Zero adjustment is recommended during initial installation and periodically as part of routine maintenance, especially if significant environmental changes occur. The push button makes this process quick and accurate.

Q: Where can the DM-2019-LCD be used?

A: It is ideal for use in industrial facilities such as clean rooms, laboratories, HVAC systems, and process control environments, particularly where accurate low-pressure measurement is essential.

Q: What is the process for reading and interpreting the display?

A: The large LCD display presents pressure readings in 1 Pa increments. Read the value directly from the screen for real-time monitoring. The display is designed for clarity and ease of interpretation in demanding environments.

Q: What are the key benefits of using this pressure transmitter?

A: Key advantages include robust industrial grade construction, rapid response time (<1 s), high measurement accuracy (1% of full scale), IP65 protection, and convenient installation and adjustment features, ensuring reliable performance and low maintenance costs.
