1. What is the measuring range of the Yunyi 3051 pressure transmitter?
The measuring range covers from -100KPa to 10MPa, including a low differential pressure starting from 0-0.2KPa, suitable for various industrial applications.

2. What accuracy levels are available for the Yunyi 3051?
We offer three accuracy classes: 0.1% FS, 0.25% FS, and 0.5% FS, allowing you to select the best fit for your specific requirements.

3. What output signals does the Yunyi 3051 support?
It supports 4-20mA two-wire output (12V-42V) and 4-20mA with HART protocol (15V-42V). The typical recommended supply voltage is 24V DC.

4. What is the protection rating of this transmitter?
The Yunyi 3051 transmitter has an IP67 protection rating, making it dust-tight and protected against temporary immersion in water, ideal for harsh industrial environments.

5. What are the temperature limits for operation and storage?

• Ambient temperature: -40°C to 85°C (with LCD display and FKM seal: -20°C to 65°C)

• Medium temperature: -40°C to 100°C

• Storage temperature: -50°C to 85°C (with LCD display: -40°C to 85°C)

6. How stable is the Yunyi 3051 transmitter over time?
The long-term stability is excellent at ±0.1% FS per 3 years, ensuring reliable and consistent performance over extended operation.

7. How do I calculate the load resistance for this transmitter?
You can calculate the load resistance using the formula: R = (U - 12) / 21mA, where U is the supply voltage. This helps ensure proper loop operation.

8. Can the Yunyi 3051 be used with an LCD display?
Yes, an optional LCD display is available. However, when installed, the ambient temperature range is limited to -20°C to 65°C, and the storage temperature range becomes -40°C to 85°C.
