Electric quantity paper recorder

1、 Overview of Power Paper Recorder
1. The power paper recorder, with its unique thermal printing recording method and advanced microprocessor control technology, achieves unparalleled high recording clarity, high precision, high reliability, multifunctionality, and ease of operation. Can be continuously recorded and digitally printed.
2. Each channel of the electric quantity paper recorder can directly select and receive multiple thermocouple, thermistor, voltage, and current signals, and can digitally display, trend, and record the measured signals. It can simultaneously record the scale value, time, and curve of each signal on a 100mm wide paper grid printed by itself, and print the channel number next to the trajectory of each channel. The measurement signal type, decimal point position, display range, recording boundary, alarm value, hysteresis, system error correction, recording ruler, data printing interval, paper feed speed, printing depth and time parameters can be set through the keyboard, and the set parameters can be protected. Electric quantity paper recorders are widely used in industries and research institutions such as pharmaceuticals, petroleum, chemical, metallurgical, and power.
2、 The main performance and technical indicators of the power paper recorder
1. Input channel: (1) Single point, double point, three-point, four point, five point, six point, eight point
(2) The type of measurement signal for each channel can be set by the user themselves
2. Channel isolation: (1) Input channels are isolated from each other without interference.
3. Display function: (2) Fixed point or cyclic display of measured values
(3) Set parameter display
(4) Alarm prompt and indicator light
(5) Time display [when all input signals are turned off]
4. Recording function: (1) Adopting imported fixed thermal head, no ink consumption, no pen position error, anti vibration
(2) There are 800 hot stamping points within a range of 100mm
(3) Trend and numerical recording of measured values
(4) Print the ruler scale and each channel mark while recording the curve
(5) Print the scale value, current time, and paper feed speed every 100mm
5. Real time: (1) Set the current date and time through the keyboard
(2) Even if there is a power outage, it does not affect normal timing
6. Curve migration function: By setting the recording boundary, the trend recording curves of different channels can be separated.
7. Scale transformation function: For voltage and current input signals, linear scale of the input signal can be displayed and recorded by setting the display range. The display range of thermocouple and thermistor signals is their measurement range.
8. Input signal type and measurement range: Various thermocouples, thermistors, standard voltage and current signals, set and selected by the keyboard.
