The Beauty of Diversity: classification and examples of field instruments

REF615 HBFLDAAHABC1ANA11G Field instruments can be divided into the following categories according to their measuring functions: temperature instruments, pressure instruments, flow instruments, level instruments, etc.

Temperature instrument: Used to measure temperature parameters in the production process. Its basic working principle is to sense the temperature change through the temperature sensor and convert the change into an electrical signal or standard signal output. For example, thermal resistors, thermocouples, etc., are common temperature sensors.

The Compact 4.0 series of thermometers from Fluke Process Instruments is a compact infrared temperature sensor specifically designed for the lithium battery and solar industry. It has an IP65 protection rating and can withstand ambient temperatures up to 180°C without additional cooling. This enables it to work for long hours in harsh environments, helping users optimize process quality and increase production efficiency.

Pressure meter: Used to measure fluid pressure or pressure difference. Its basic REF615 HBFLDAAHABC1ANA11G working principle is to use elastic elements to produce deformation under pressure, and convert the deformation into electrical signals or standard signal output. For example, pressure transmitters, differential pressure transmitters, etc., are common pressure instruments.

Emerson Rosemount™, Paine™, and Roxar™ pressure meters provide solutions to challenging measurement challenges in a wide range of harsh environments. Provide you with comprehensive information to help you make decisions about productivity, quality, energy management and safety.

Flow meter: Used to measure fluid flow. Its basic working principle is to calculate the flow rate by measuring the pressure, temperature, flow rate and other parameters when the fluid flows through the pipeline. For example, vortex flowmeters, electromagnetic flowmeters, etc., are common flow meters.

Level meter: Used to measure the level or height of liquid or solid materials. Its basic working principle is to calculate the REF615 HBFLDAAHABC1ANA11G liquid level or height by measuring the resistance, capacitance and other parameters caused by the change of liquid level or height. For example, ultrasonic level meters, radar level meters, etc., are common level instruments.

For radar level measurement, E+H’s Micropilot level meter can be installed from the top down to meet all industry application requirements. Non-contact radar commissioning is simple, trouble-free operation, saving time and cost. A wide range of applications can be used in simple storage tanks, corrosive media or high-precision tank table applications.

The prosperity is not finished, the future REF615 HBFLDAAHABC1ANA11G can be expected: the innovation and prospect of field meters

With the rapid development of science and technology, the field instrument has developed from a single measuring tool to a multi-functional comprehensive equipment. In the future, we expect field instrumentation to become more intelligent and networked to adapt to more complex and demanding industrial environments. Under the wave of Industry 4.0 and intelligent manufacturing, field meters will continue to play an important role in bringing more convenience and efficiency to industrial production.

The temperature meter can control the temperature in the reactor stable within the preset range by automatically adjusting the power of the heating element; The pressure meter can control the pressure in the pipeline to be stable within the preset range by automatically adjusting the opening of the valve. The implementation of these control instructions will greatly improve the automation level and efficiency of industrial production, and bring more convenience and benefits to industrial production. Therefore, we look forward to the next article on the field instrument executing various control instructions, revealing more possibilities for future industrial production.
