Explosion proof integrated temperature transmitter

Explosion proof integrated temperature transmitter is a device that integrates temperature sensors and transmitters. It can convert temperature signals into standard electrical signals (such as 4-20mA DC) for display, recording, adjustment, or transmission. Its working principle is mainly based on the temperature measurement principle of temperature sensors such as thermistors or thermocouples. Temperature signals are obtained through measurement circuits, and then converted into standard voltage or current signals through signal conversion circuits.

Widely used in industrial fields such as petroleum, chemical, metallurgical, and power, especially in hazardous areas with flammable gases or vapors of flammable liquids, it can accurately measure temperature and convert signals into standard electrical signals for output, ensuring the safe and stable operation of industrial processes.

The explosion-proof integrated temperature transmitter mainly consists of the following parts:

Temperature sensor: usually using temperature sensing elements such as thermistors or thermocouples, used to convert temperature signals into changes in resistance or thermoelectric potential.

Measurement circuit: used to measure the resistance value or thermoelectric potential of a temperature sensor and convert it into a weak analog signal.

Signal conversion circuit: including functions such as amplification, filtering, and linear conversion, used to convert weak analog signals obtained from measurement circuits into standard voltage or current signals.

Explosion proof enclosure: Made of explosion-proof materials to provide explosion-proof protection and prevent explosions caused by electric sparks or arcs.

Characteristics and advantages of explosion-proof integrated temperature transmitter:

Explosion proof performance: It has excellent explosion-proof performance and can be safely used in explosive environments.

High precision: Using manufacturing processes and high-quality materials to ensure the accuracy of measurement results.

Good stability: The design is reasonable and can maintain long-term stability under harsh working conditions.

Easy installation: Integrated design, easy and fast installation, reducing the workload of on-site installation.

When selecting explosion-proof integrated temperature transmitters, parameters such as measurement range, accuracy level, output signal type, and explosion-proof level need to be determined based on actual measurement requirements. At the same time, it is necessary to consider the properties of the measured medium (such as corrosiveness, temperature, etc.) and the requirements of the working environment (such as humidity, pressure, etc.). During installation, it should be ensured that it is firmly fixed to avoid the influence of mechanical shock and vibration. At the same time, wiring and debugging should be carried out according to the manufacturer's instructions to ensure the accuracy of the measurement results. In addition, attention should be paid to protecting the instrument from corrosive media and ensuring the integrity of the explosion-proof shell.

In order to ensure the accuracy and stability of the explosion-proof integrated temperature transmitter, it is necessary to regularly maintain and upkeep it. Specifically, it includes:

Regular inspection: Check whether the appearance of the instrument is intact, whether the wiring is loose, and whether the explosion-proof shell is complete.

Cleaning and maintenance: Regularly clean the surface and internal components of the instrument panel to remove accumulated dust and dirt on the surface. At the same time, it is necessary to keep the interior of the instrument dry and clean to avoid the invasion of moisture and corrosive media.

Calibration and adjustment: During long-term use, it is necessary to regularly calibrate and adjust the instrument to ensure the accuracy of its measurement results. This usually requires the use of standard calibration equipment for calibration and following the calibration procedures provided by the manufacturer.
