TTH300 ABB Integrated temperature transmitter

1、 Basic Overview
Product type: Integrated temperature transmitter
Brand: ABB
Model: TTH300
Communication protocol: Supports multiple communication protocols such as HART, PROFIBUS PA, or FOUNDATION Fieldbus
2、 Technical features
Two wire system technology: TTH300 adopts two wire system technology, which simplifies wiring, reduces costs, and improves system reliability.
Enhanced diagnostic information: This transmitter provides enhanced diagnostic information that helps users locate and resolve potential issues more quickly.
High precision measurement: TTH300 has high-precision measurement capability, which can ensure the accuracy and reliability of temperature data.
Multifunctionality: Supports multiple input functions, including mean measurement and difference measurement of a single sensor and two sensors, sensor redundancy, and sensor drift monitoring.
3、 Specification parameters
Measurement range: The measurement range of TTH300 may vary depending on the type of sensor (such as thermistor, thermocouple, etc.). For example, for a thermistor (Pt100), its measurement range may comply with standards such as IEC 60751.
Input resistance: Supports a wide range of input resistance to meet different sensor and measurement needs.
Measuring current: Measuring current is relatively small, which helps reduce the impact on the sensor and improve measurement accuracy.
Sensor connection types: Supports multiple sensor connection types such as two-wire, three wire, and four wire to adapt to different application scenarios.
4、 Application scenarios
The TTH300 ABB temperature transmitter is widely used in various industrial fields that require precise temperature measurement, such as petrochemicals, power, metallurgy, pharmaceuticals, etc. It can be used in conjunction with various sensors and heat pipes to collect, convert, and transmit temperature signals.

Recently, ABB Group, headquartered in Switzerland, has attracted industry attention for a technology called “Flash Charging”. According to the information obtained from ABB (China) Enterprise Communication Department, “This technology was designed to be promoted globally

The system has been operating on the route between Geneva Airport and Palexpo Exhibition Center since May 26th and will continue until March 14th, 2014. The head of the company stated that this technology is suitable for ordinary cities, large cities, and mega cities seeking sustainable public transportation solutions. Used for high-frequency bus routes to alleviate traffic congestion in urban areas

According to ABB, this technology is equipped with a water-cooled lithium titanate oxide LTO battery pack with a service life of 10 years. There is a rooftop charging system at the station that can charge for 15 seconds at a power of 400 kilowatts. These charging systems are connected to the power grid and equipped with intermediate storage devices (supercapacitors) to reduce the impact of short-term high power on the grid. The fast charging point can charge buses up to 1.65 kWh. In addition, at the bus terminal, there is a 200 kW charger that can fully charge the battery in 3-4 minutes.

At present, pure electric buses using this technology can carry 135 people. When the vehicle stops at the station, it is located by infrared, and the charging point on the roof is connected to the moving arm controlled by laser after positioning. After completing a 15 second recharge, the vehicle continues to move forward without affecting the normal operation of the bus. Its concept is similar to that of a tram, but it does not require the installation of a complex network.

In addition to ABB, similar concepts of fast charging during driving are also being promoted by many companies in China. During an interview with reporters, Wang Binggang, the leader of the supervision and consulting expert group for the National 863 Program’s major projects on energy conservation and new energy vehicles, referred to this mode as “online charging” The online charging mode can effectively solve the contradiction between battery quantity and range Wang Binggang stated. It is reported that currently, bus companies such as Hunan CSR Times Electric Vehicle, Youth Bus, and Hengtong Electric Vehicle are developing and promoting similar technologies.

As a Fortune 500 company, ABB’s business scope includes power and automation technology. In the field of electric vehicles in China, ABB is a supplier of DC drives, motors, programmable controller products, electric vehicle charging infrastructure, and energy storage products. In the field of charging infrastructure, ABB has not had a good opportunity, perhaps the latest “flash charging technology” can find some market space for ABB.
