Product Details
Introduction
This gas water heater detection system (WKGZ-WH56D) adopts a computer centralized distributed measurement and control system. The overall system mainly consists of an industrial control computer, a data acquisition board, and various types of sensors. The data acquisition board collects sensor signals, processes them, and returns them to the industrial control computer. The upper computer software of the industrial control computer is installed to process and calculate the data and implement it.
This gas water heater detection system mainly includes a testing core box, peripheral sensors, angle seat valves or solenoid valves. The peripheral sensors are configured with all relevant sensors except for electromagnetic flow meters and gas flow meters by default. Users can also add electromagnetic flow meters and gas flow meters as needed.
The current model, compared to (WKGZ-WH56CA), also meets the requirements of hardware acquisition and control, including GB6932、EN26、EN13203-2&Regulation 812、 Energy efficiency level testing including 814 (European standard ERP), 10CFR Pt.430 Subpt. B APP. E (American standard), AS5263.1.2 (Australian standard), and some routine testing have been conducted. In addition, WiFi and Bluetooth (with external antenna configuration), 2 sets of RS232 communication interfaces (for expanding the access of flue gas analyzer and programmable power supply), and 1 set of control valve interfaces have been added to the hardware.
