Value sterilization recorderMain performance and technical indicators
1. Input channel: The type of measurement signal for each channel from 1 to 8 points can be set by the user themselves
2. Channel isolation: Input channels are isolated from each other without interference.
3. Display function: fixed-point or cyclic display of measured values, display of set parameters [in set state] alarm prompts and hints, time display [when all input signals are turned off]
4. Recording function: Using an imported fixed thermal head, there is no ink consumption, no pen position error, and shock resistance. There are 800 thermal printing points within a range of 100mm, which can record the trend and number of measured values. At the same time, the curve is recorded, and the scale scale and each channel mark are printed every 100mm. The scale value, current time, and paper feed speed are also printed
5. Real time: The current date and time are set by the keyboard, and 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
Number, selected by keyboard settings.
9. Paper speed: The paper speed can be set freely through the keyboard, ranging from 10 mm/h to 1990 mm/h.
10. Alarm function: Provides six sets of relay contact outputs, which can be combined by users at will. Each channel alarm can select upper limit, lower limit, difference upper limit, and difference lower limit. The alarm hysteresis of each channel can be set, and there is an indicator light when the relay is activated. Relay contact capacity: 24VDC, 3A；220VAC, 3A
11. Communication: RS232C or RS485 communication interface
12. Analog output: Two channels of 4-20 mA analog transmission output
13. Sampling period: 0.6S
14. Digital display and alarm accuracy: 0.2%FS?
15. Trend recording accuracy: 0.2%? Two pieces
16. Digital recording accuracy: 0.2%FS?
17. Input impedance: greater than 10M ohms [Note: When measuring current, the input impedance is 250 ohms]
18. Power consumption: not exceeding 30W
19. Normal working environment: Temperature range: 0-50 degrees, humidity range: 10-85% RH
20. Power supply voltage: 220 V; 50 Hz
21. External dimensions: 144 × 144 × 200 mm
22. Hole size: 138 × 138 mm
