stem or root of plantsSmall long chart with paper recorderWith a unique thermal printing recording method and advanced microprocessor control technology, unparalleled high recording clarity, high precision, high reliability, multifunctionality, and ease of operation have been achieved. Can be continuously recorded and digitally printed.
Small long chart with paper recorderEach channel of can directly select and receive multiple thermocouple, thermistor, voltage, and current signals, and can digitally display and record trends and numbers of the measured signals. It can simultaneously record scale values, time, and curves 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. Widely used in industries and research institutions such as medicine, petroleum, chemical, metallurgical, and electric power.
IISmall long chart with paper recorderMain performance and technical indicators
1. Input channel: Single point, double point, three-point, four point, five point, six point, eight point
·The type of measurement signal for each channel can be set by the user themselves
It can also be specified when placing an order. [Set by the manufacturer for the user]
2. Channel isolation: Input channels are isolated from each other without interference.
3. Display function: Fixed point or cyclic display of measured values
·Set parameter display [in set state]
·Alarm prompt and indicator light
·Time display [when all input signals are turned off]
4. Recording function: Using imported fixed thermal head, no ink consumption, no pen position
Error, anti vibration
·There are 800 hot stamping points within a range of 100mm
·Trend and numerical recording of measured values
·Print the ruler scale and each channel mark while recording the curve
·Print the scale value, current time, and paper feed speed every 100mm
5. Real time: Set the current date and time through the keyboard
·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 conversion 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 types and measurement ranges: Various thermocouples, thermistors, standard voltage and current signals can be set and selected by the keyboard. TABLE I
