以独特的热打印记录方式和先进的微处理器控制技术，实现了无与伦比的高记录清晰度、高精度、高可靠性、多功能且便于操作。 The DXR-1000 paper recorder uses a unique thermal printing recording method and advanced microprocessor control technology to achieve unparalleled high recording clarity, high precision, high reliability, multi-function and easy operation. Paper recorder can record continuously and print digitally.
Each channel of the DXR-1000 paper recorder can directly choose to receive a variety of thermocouple, thermal resistance, voltage and current signals, and can digitally display the measured signal and perform trend recording and digital recording. Record the scale value, time and the curve of each signal at the same time on the printed 100mm wide paper grid, and print the channel number beside the track of each channel. With paper recorder, you can set parameters such as measurement signal type, decimal point position, display range, recording boundary, alarm value, hysteresis, system error correction, recording scale, data printing interval, paper feed speed, print depth, and time. , And protect the set parameters. Paper recorders are widely used in pharmaceutical, petroleum, chemical, metallurgy, power and other industries and scientific research units.
主要性能及技术指标 Main performance and technical indicators of paper recorder
1. Input channel single point, double point, three points, four points, five points, six points and eight points. The measurement signal type of each channel can be set by the user or specified when ordering. [Set by the factory for users]
2. Channel isolation: Input channels are isolated from each other without interference.
3． Display function: Fixed-point or roving display of measured value Setting parameter display [under setting state]
Alarm prompt and reminder light time display [in the case that all input signals are turned off]
4． Recording function: Imported fixed thermal head, no pen and ink consumption, no pen position error, anti-vibration, 800 thermal print points in the 100mm range. Trend measurement and digital recording of measured values are recorded on the recording curve. Each channel mark prints the scale value, current time and paper feed speed every 100mm
5． Real-time time: Set the current date and time by the keyboard, even if the power is off, it will not affect the normal timing
6. 边界的设定，可使不同通道的趋势记录曲线分离开。 Curve migration function: By setting the boundary of the paperless recorder , the trend recording curves of different channels can be separated.
7. Scale conversion function: For voltage and current input signals, you can display and record the linear scale of the input signal by setting the display range. The display range for the thermocouple and thermal resistance signals is its measurement range.
8. Input signal type and measurement range: Various thermocouples, thermal resistors, standard voltage and current signals can be selected and set by the keyboard.

9. Paper feed speed: Set arbitrarily through the keyboard, paper feed speed is 10 mm / h to 990mm / h.
10． Alarm function:
Provides six groups of relay contact outputs. The user can select any combination of alarms for each channel. The upper limit, lower limit, difference upper limit, and difference lower limit can be set. The alarm return of each channel can be set. When the relay is activated, an indicator light prompts the relay to contact. Point capacity: 24VDC, 3A; 220VAC, 3A
11. Communication: RS232C or RS485 communication interface can be provided. [This item is an extended function, which must be specified when ordering]
