This is a compact instrument that integrates three major functions: temperature measurement, signal transmission and local indication. It is a "versatile player" for temperature monitoring in industrial fields.

1. Local real-time monitoring: On-site inspection personnel can directly read the temperature values without relying on the control room DCS, quickly determine the operating status of the equipment, and respond to abnormalities quickly.
2. Simplified system architecture: Eliminates the need for separate local temperature indicators, reducing installation points and procurement costs. One instrument with two functions, economical and efficient.
3. Convenient for commissioning and maintenance: When calibrating and setting parameters (such as range), local comparison with the displayed values can be done, eliminating the need for repeated checks with the control room, resulting in high efficiency and low error.
4. High reliability: The signal is converted to a 4-20mA standard signal on-site, providing strong anti-interference capability during transmission and avoiding the problem of weak sensor signals (such as thermocouple mV signals) being easily interfered with during long-distance transmission.
5. Flexibility: The display content is usually configurable (such as displaying engineering units °C/°F, displaying output current percentage, maximum/minimum values, etc.).

1. Temperature monitoring of industrial pipelines and tanks:

• Scenario: Process pipelines, reactors, and storage tanks in the petroleum, chemical, and pharmaceutical industries.
• Value: Clear and visible during the rounds of inspection by operators.
• HVAC and energy systems:
• Scenario: Supply and return water pipes, heat exchangers, and boiler inlets and outlets of central air conditioning systems.
• Value: Facilitates system commissioning and energy efficiency inspections.
• Monitoring of mechanical equipment status:
• Scenario: Surface or lubricating oil temperature monitoring of compressors, motors, bearings, and gearboxes.
• Value: A key indicator for preventive maintenance, with on-site immediate readability.
• Laboratories and test benches:
• Scenario: Experimental devices that require simultaneous recording and transmission of temperature data.
• Value: Local readings are intuitive, and data is simultaneously uploaded to a computer.
• Food and beverage and clean environments:
• Scenario: Tanks and pipelines that need to meet hygiene standards (such as SIP/CIP).
• Value: Integrated transmitter with a sanitary clamp connection, and the display part is easy to clean.

The on-site display temperature transmitter is a perfect example of "functional integration" and "local information" in the field of industrial temperature measurement. The core problem it solves is: while transmitting temperature signals to the control room over a long distance, how to provide on-site operators and maintenance personnel with immediate and reliable local readings for convenient reference, thereby improving inspection efficiency, simplifying system structure and enhancing the convenience of debugging and maintenance.
