Product Description of TWC-201 Multi-channel Temperature Recorder: ◆ 5.6-inch 320X234 dot matrix high-brightness blue screen graphic liquid crystal display, with LED backlight, clear image and wide viewing angle. ◆ The screen contrast can be adjusted freely. ◆ With a high-speed and high-performance 32-bit ARM microprocessor, the screen response time is less than 0.2 seconds, and it can simultaneously detect, record, display and alarm for 12 channels of signals. ◆ Adopting the latest large-scale integrated circuits and carefully designed with components from internationally renowned manufacturers. ◆ A large-capacity FLASH memory chip stores historical data, and the data will never be lost even in case of power failure. ◆ Fully isolated universal input, capable of inputting multiple types of signals. No jumper is required, and it can be configured through software. ◆ The displayed value range of engineering quantities is wide, and it can display 5-digit values: -9999 ~ 19999. ◆ Supports the display of vacuum degree in scientific notation. ◆ Chinese menu configuration, displaying engineering tag numbers and engineering units. The software password lock ensures the security of user configuration. ◆ Built-in national standard second-level character library (6500 Chinese characters); with the brand-new T6 input method, it is convenient to operate. It supports Chinese pinyin input, and free input of numbers, English, special symbols, subscripts and superscripts, etc. It adopts international standard coding to solve the input problems of special units and Chinese tag numbers. ◆ Customizable combined input of Chinese tag numbers and units. ◆ Alarm display, indicating the lower-lower limit, lower limit, upper limit and upper-upper limit alarms of each channel at the same time. It can record the latest 15 alarm messages. ◆ Uses a USB2.0 interface to transfer and back up historical records, and supports 256M, 512M, and 1G USB flash drives; the historical record files can be recognized by Windows. ◆ Standard serial communication interfaces: RS-485 and RS-232C. ◆ Provides various data types, such as percentage values, engineering quantities, cumulative quantities, etc. ◆ Can be externally connected to a miniature printer, supporting manual printing and timed automatic printing to meet the on-site printing needs of users. ◆ Integrated hardware real-time clock, and the clock can run accurately even in case of power failure. ◆ New type of switching power supply, which can work normally within the range of 85VAC~265VAC. ◆ Provides isolated power distribution of +24VDC for the transmitter. ◆ Rich compensation models, which can compensate for various media such as liquids, general gases, steam, natural gas, etc. ◆ Small flow rate compensation metering function, and it will be compensated according to the set value after the instrument experiences a power failure. ◆ Provides 8-hour shift reports, 12-hour shift reports, daily reports, and monthly reports. The settlement time can be set freely. ◆ When the temperature sensor or pressure sensor fails, it will automatically switch to the set temperature and calculate the compensation amount based on the pressure. ◆ Has the power failure recording function. It records the power-on and power-off time of the recorder, displays the cumulative power-off time, and prevents users from stealing steam during power outages. ◆ Fully aluminum sealed housing and internal shielding plate ensure that the instrument works normally in harsh environments.
