The 3051 Pressure Transmitter is a popular model of pressure transmitter manufactured by Rosemount, a leading provider of process measurement and control instruments. The 3051 Pressure Transmitter is widely used in industrial applications to accurately measure and transmit pressure readings.
This transmitter utilizes advanced technology to provide precise and reliable pressure measurements. It features a robust design that can withstand harsh environments and extreme temperatures. The 3051 Pressure Transmitter is known for its high accuracy, stability, and long-term reliability, making it suitable for critical process control and monitoring applications.
One of the key features of the 3051 Pressure Transmitter is its scalability. It can be configured with various options, such as different pressure ranges, output signals (4-20 mA, HART, FOUNDATION Fieldbus), and communication protocols. This flexibility allows for seamless integration into different control systems and ensures compatibility with existing infrastructure.
The 3051 Pressure transmitter output is too small or no output #
Possible causes and solutions:
1.Transmitter installation and working conditions #
A. Check if the transmitter is installed correctly, if there is any leakage, and the measuring range and working conditions meet the requirements;
B. Check whether the characteristics of the measured medium change, such as crystallization, hardening, etc., which may affect the output.
C. Whether the zero points error is cleared after the installation is completed, and whether the double flange remote transmission transmitter is correctly migrated.
2.transmitter electrical connection #
A. Check if the voltage applied to the transmitter is normal and the load capacity is sufficient;
B. Check whether the power signal line circuit is open or multi-point grounded;
C. Check if the lead wire of the transmitter sensor component is short-circuited;
D. Check whether the positive and negative polarity of the power signal line are reversed;
3.pressure tube #
A. Check if the pipe pressure connection is correct;
B. Check if the pressure guiding tube is leaking or blocked;
C. Check whether there is gas in the liquid-filled pressure guiding tube;
D. Check the presence or absence of deposits in the pressure chamber of the transmitter;
E. Check if the shut-off valve is fully open and the balance valve is closed;
F. Check if the specific gravity of the liquid in the pressure guiding tube changes.
4.The transmitter circuit module is faulty #
The 3051 series of intelligent pressure/differential pressure transmitter circuits have been modularized. A total of: analog modules, digital modules and display modules. Among them, only the analog module and the digital module cannot be replaced by themselves, and must be sent to the company for repair, and the display module can be replaced on site. If the problem still cannot be solved after the replacement, it must be sent to the company for repair and settlement.
The 3051 Pressure transmitter output is too large #
Possible causes and solutions:
1.Transmitter installation and working conditions #
A. Check if the installation of the transmitter is correct, and
whether the measurement range and working conditions meet the requirements;
B. Check whether the measurement range of the disposable component (such as the orifice plate) meets the requirements.
C. Whether the zero points error is cleared after the installation is completed, and whether the double flange remote transmission transmitter is correctly migrated.
2.transmitter electrical connection #
A. Check if the voltage applied to the transmitter is normal and the load capacity is sufficient;
B. Check if the power supply circuit is short-circuited;
C. Check if the connector is correctly connected, whether the contact is clean, and whether it is reliable.
3.pressure tube #
A. Check if the pipe pressure connection is correct;
B. Check if the pressure guiding tube is leaking or blocked;
C. Check whether there is liquid in the gas pressure guiding tube, and whether there is gas in the liquid pressure guiding tube;
D. Check the presence or absence of deposits in the pressure chamber of the transmitter;
E. Check if the shut-off valve is fully open;
F. Check if the specific gravity of the liquid in the pressure guiding tube changes.
3051 Pressure transmitter unstable output #
Possible causes and solutions:
1.transmitter electrical connection #
A. Check if the voltage applied to the transmitter is normal and the load capacity is sufficient;
B. Check if the power supply has intermittent short circuit or open circuit;
C. Check if the transmitter casing is reliably grounded and there is strong interference around it;
D. Check if the connector is correctly connected, whether the contact is clean, and whether it is reliable.
2.The measured medium fluid fluctuates and adjusts the damping time of the circuit. #
3.pressure tube #
A. Check if the pipe pressure connection is correct;
B. Check if the pressure guiding tube is leaking or blocked;
C. Check whether there is liquid in the gas pressure guiding tube, and whether there is gas in the liquid pressure guiding tube;
D. Check the presence or absence of deposits in the pressure chamber of the transmitter;
The 3051 Pressure transmitter cannot communicate normally #
Possible causes and solutions:
1.transmitter electrical connection #
A. Check if the voltage applied to the transmitter is normal and the load capacity is sufficient;
B. Check if the transmitter casing is reliably grounded and there is strong interference around it;
C. Check if the load resistance meets the requirements and whether the electrical performance meets the requirements of the HART protocol.
2. HART communication computer or handheld communicator #
A. The communication computer or the handheld communicator is faulty or the version is incompatible;
B. The communication connection line is broken;
C. The communication modem is faulty.
(4) Transmitter output confusion
The user misinterprets the transmitter data by using the buttons on the transmitter or the HART communication software or the Communicator to communicate the configuration error. Restore the original settings or reconfigure with the “Restore factory settings” function.
