Function Of Transmitter

May 20, 2024 Leave a message

The function of transmitter is to detect process parameters and transmit the measured values in the form of specific signals for display and adjustment.

In the automatic detection and adjustment system, the function is to transform various process parameters such as temperature, pressure, flow, liquid level, composition and other physical quantities into a unified standard signal, and then transmit it to the regulator and indicating recorder for adjustment, indication and recording.

High Quality 4-20mA RS485 Split Four-Wire Radar Liquid Le...
Applications1.Petrochemical Industry1.In petrochemical plants, the accurate measurement of liquid levels in large storage tanks is of utmost importance. The Split Two - line Radar Level Meter precisely gauges the levels of various chemical raw materials and products, be it highly volatile hydrocarbons or viscous polymers. This ensures safe storage, efficient production processes, and seamless inventory management.1.Food and Beverage Industry1.For the food and beverage sector, maintaining the correct liquid volume in fermentation tanks, storage silos, and processing vessels is crucial for product quality and process control. The meter provides real - time and reliable level data, enabling optimal fermentation conditions, accurate filling of containers, and minimizing product waste.1.Water and Wastewater Treatment1.In water treatment plants, from raw water intake to treated water distribution, and in wastewater treatment facilities, from sewage collection to effluent discharge, the meter plays a vital role. It accurately measures water levels at different treatment stages, ensuring the proper functioning of pumps, valves, and other equipment, and facilitating compliance with environmental regulations.Usage Method1.Installation1.G2 Thread Installation: When using the G2 thread installation method, carefully screw the sensor of the radar level meter onto the pre - threaded connection point on the tank or container. Ensure a tight and secure fit to prevent any leaks or misalignment that could affect the measurement accuracy.1.Flange Installation: For flange - based installation, align the flange of the sensor precisely with the corresponding flange on the equipment. Use high - quality bolts to fasten the two flanges together, applying the appropriate torque to achieve a leak - proof and stable connection.1.Bracket Installation: First, firmly attach the bracket to a stable structure near the measurement area. The structure should be able to support the weight of the sensor and withstand any vibrations or mechanical stress. Then, mount the sensor onto the bracket, adjusting its position to ensure optimal measurement coverage.1.Connection and Power - up1.Connect the dedicated cable that links the sensor to the display unit. This cable serves a dual function: it transmits the measured data from the sensor to the display and supplies power to the sensor. Next, connect a DC24V power source to the system, taking care to observe the correct polarity. Once powered on, the large - screen, high - brightness LCD on the display unit will light up, displaying the initial status of the meter.1.Operation1.The radar ranging module, equipped with an 80G high - frequency chip, starts to emit radar waves. These waves can penetrate through solid and liquid media alike, accurately measuring the distance to the target surface. The measured data is then processed by the meter's internal microcontroller and converted into liquid level or distance information, which is clearly shown on the LCD.1.To adjust the settings or switch between Chinese and English, simply use the control buttons on the display unit. These buttons are designed for easy operation, allowing users to navigate through the menu options effortlessly. The meter stably outputs a 4 - 20mA current signal, which can be easily connected to Programmable Logic Controllers (PLCs) or other control systems for further data processing and control. Additionally, with its RS485 communication output, it can be integrated into larger industrial networks for centralized monitoring and management.

The Split Two - line Radar Level Meter is an innovative and dependable device designed for precise level measurement. It has become an indispensable tool across a wide spectrum of industrial and commercial fields, thanks to its advanced features and high - performance capabilities.
High Qyality 4-20mA Ultrosonic Level Difference Gauge
Blind Zone: The gauge has a blind zone ranging from 0.35 - 0.5m. This is due to the design of the ultrasonic transducer and the signal processing circuit, which is carefully calibrated to ensure reliable performance even in the presence of a small blind zone.Measurement Accuracy: The measurement accuracy is 0.5%FS. This means that across the entire 20m measurement range, the maximum error in measuring the level difference is only 0.1m (0.5% of 20m). Such high - precision measurement is crucial for applications where even a small deviation in level difference can have significant consequences.Sound Beam Angle: The sound beam angle is ±8°. This narrow beam angle allows for precise targeting of the measurement area, minimizing the impact of external factors such as reflections from nearby objects and enhancing the accuracy of the level difference measurement.Working Humidity: The TSL300CJ can operate efficiently within a humidity range of 0 - 60%. The instrument is designed with moisture - resistant materials and coatings to protect its internal components from the harmful effects of humidity, ensuring stable performance in both dry and humid environments.
