MR3142 Characteristic Variable Device of Hydraulic Turbine Hydrology Trainers Didactic Equipment Educational Equipment
1. Product Introduction
1.1 Product Description
The current economic development model, built upon the consumption of non-renewable energy sources such as coal, oil, and natural gas, has led to increasingly prominent environmental pollution and the greenhouse effect. To achieve sustainable development and establish a harmonious relationship between humanity and nature, developing green energy sources such as wind, hydro, solar, biomass, geothermal, and ocean energy has become a topic of great concern to countries worldwide.
Hydropower is a clean energy source. Currently, its utilization primarily involves converting potential energy into mechanical energy, and then into electrical energy, through a hydroelectric generator. The efficiency of energy utilization depends on the turbine's conversion rate.

1. Level Gauge: Responsible for displaying the real-time water level and temperature in the tank and informing the experimenters.
2. PVC Ball Valve: An industrial valve made primarily of polyvinyl chloride (PVC), using a ball rotation design to control fluid flow. The nominal diameter is DN20 (corresponding to a pipe outer diameter of approximately 26.9mm). This valve features corrosion resistance, lightweight durability, and good sealing performance, and is widely used in chemical, water treatment, environmental protection, and agricultural irrigation fields. It is suitable for conveying corrosive media or clean water.
3. Analog Output Module: This module is a high-precision, industrial-grade analog signal output device, specifically designed for scenarios requiring the conversion of digital control signals into standard 4-20mA current signals. The module supports one independent 4-20mA output and enables remote communication with PLCs, HMIs, SCADA systems, or host computers via an RS485 bus interface. Using the Modbus RTU/ASCII protocol, it can be flexibly integrated into various industrial automation systems and is widely used in process control, equipment driving, and data acquisition scenarios.
4. DC power supply: Converts AC220V alternating current to DC24V direct current
