FRD Sensor FD3051ST Smart Pressure Transmitter: Solving Pressure Measurement

The FRD Sensor FD3051ST Smart Pressure Transmitter is designed for reliable pressure measurement and process control in industrial applications.

The FD3051ST covers a pressure range of 0–0.1 kPa to 40 MPa, with accuracy grades from ±0.05%FS to ±0.5%FS at 25°C and full scale. It supports 4–20 mA + HART and RS485 communication, and is suitable for measuring liquids, gases, and steam.

With an ambient temperature range of −40°C to +80°C and stability of 0.1% URL / 3 years, the FD3051ST is suitable for industrial automation, process equipment, system integration, and OEM applications.

Selecting a pressure transmitter requires more than simply matching the pressure range. OEMs and system integrators also need to consider accuracy, communication compatibility, environmental conditions, and customization requirements.

The FD3051ST addresses common challenges through:

1. Wide Pressure Range

The FD3051ST supports 0–0.1 kPa to 40 MPa, allowing customers to select configurations for different pressure measurement requirements.

2. Flexible Accuracy Selection

Multiple accuracy grades are available, from ±0.05%FS to ±0.5%FS, helping customers balance measurement requirements and overall equipment cost.

3. Flexible Industrial Communication

The transmitter supports 4–20 mA with HART digital protocol and RS485, facilitating integration with PLC, DCS, and other industrial control systems.

4. Reliable Industrial Operation

With an ambient temperature range of −40°C to +80°C, the FD3051ST is designed for a wide range of industrial environments.

5. OEM-Friendly Configuration

FRD Sensor supports OEM/ODM, Private Label, and mechanical/electrical customization, providing greater flexibility for equipment manufacturers and system integrators.

FRD Sensor provides OEM and ODM customization services for the FD3051ST to support different equipment and system integration requirements.

Customization options may include:

• Pressure range and accuracy grade
• Process and electrical connections
• Output and communication configuration
• Mechanical structure
• Nameplate, logo, and Private Label
• Product labeling and packaging

FRD Sensor supports customers from technical requirement confirmation and sample development to mass production, helping OEM customers simplify integration and maintain consistent batch quality.

Measurement deviation can sometimes result from installation, wiring, environmental conditions, or incorrect configuration rather than the transmitter itself.

1. Check the Pressure Range

Confirm that the selected pressure range matches the actual operating pressure.

2. Check Installation

Inspect the process connection, pressure line, sealing, and installation condition for leakage or blockage.

3. Check Temperature

Confirm that the operating environment is within the specified −40°C to +80°C range.

4. Check Power and Wiring

Verify the 12–32 VDC power supply, wiring polarity, grounding, and output loop.

5. Check Communication

For HART or RS485 applications, verify communication settings, wiring, and configuration parameters.

6. Check Calibration

If measurement deviation remains after the above checks, verify the transmitter using a calibrated pressure source and follow the appropriate calibration procedure.

FRD Sensor FD3051ST Pressure Transmitter combines high accuracy, stable performance, and strong environmental adaptability to meet modern industrial pressure measurement requirements.

With flexible OEM & ODM customization capabilities and reliable technical support, FRD Sensor provides efficient and dependable pressure measurement solutions for global industrial applications.
