Digital display light column indication adjustment alarm instrument

XGTH-510, XGTA-810, and XMTA-810 display control instruments are intelligent display control instruments improved on the basis of the company's original light column indicating digital display adjustment alarm instrument, which integrates digital measurement display and analog measurement display. LEDs accurately display real-time measurement values, while using high-precision 100-line light columns to clearly and intuitively simulate real-time measurement ranges. The instrument uses a microprocessor for mathematical operations, and can be used for measurement and control of various temperatures, pressures, liquid levels, etc. Using jumper-free technology, it is possible to switch and input a variety of graduation numbers. When changing the input graduation number, there is no need to change jumpers or switches. Just set the graduation number and related parameters of the instrument, and the input graduation number can be completed online. Change. Communication interfaces (such as RS-485, etc.) can also be provided according to user requirements to communicate with various devices with input and output to form an intelligent management system.

Features

1. The dedicated integrated instrument chip has more reliable anti-interference and stability.
2. Universal signal input, which can be connected with commonly used thermal signals through menu settings.
3. The display range, transmission output range, alarm value and alarm mode can be modified online.
4. The anti-interference mode combined with software and hardware can effectively suppress the on-site interference signal.
5. Digital calibration technology, no adjustable parts such as potentiometers.
6. The temperature of the cold junction of the thermocouple and the resistance of the thermal resistance lead are automatically compensated.
7. It can provide power distribution function for external two-wire and three-wire transmitters.
8. With photoelectric isolation transmission output function.
9. It has the function of light column analog display.
10. With RS232 or RS485 communication function, it can be connected with the host computer to form a data acquisition system and a control system.
11. Equipped with six relay alarms (the instrument with this function needs to be ordered separately).
