Essential for energy audits of HVAC systems (Chillers/Boilers) in transport facilities without cutting pipes. Technical Specifications: • Measurement Principle: Transit-Time Ultrasonic. • Medium: Conductive and non-conductive liquids with low gas/solid content. • Pipe Diameter Coverage: Set of transducers covering approx. DN15 to DN600 (0.5" to 24"). Note: Huge diameters (380") are not required for facility audits. • Temperature Range: Sensors suitable for -30°C up to +130°C (covering chilled water and hot heating water). • Heat Metering (Energy): Capability to calculate Thermal Energy (kWh/BTU) by integrating temperature inputs (includes 2x Clamp-on Temperature sensors PT100). • Interface: Robust Handheld unit OR Tablet with large color display. • Data Logging: Internal memory (>100,000 points) and USB/Bluetooth export to PC. • Protection: IP65 (Sensor) / IP40+ (Unit) for field use. • Accessories: Coupling gel, clamping chains/magnets, rugged carrying case. Didactic Requirement: A mandatory component is a action oriented student guide explaining the "Transit Time" principle and how to calculate thermal power ($Q = m \cdot c \cdot \Delta T$). | 1 | |
| 2 | Professional Ultrasonic Leak Detector & Data Logger | Description: Handheld professional ultrasonic detector for locating and quantifying leaks in compressed air, gas, and vacuum systems. Essential for energy audits as compressed air leaks are among the most expensive energy wastes in industry. Technical Specifications: • Measurement Principle: Heterodyne ultrasonic detection (converts high-frequency leak noise into audible sound and digital values). • Frequency Range: Centered around standard ultrasonic frequencies (approx. 35 – 45 kHz) with adjustable bandwidth or tuning. • Display: Digital LCD/Touchscreen displaying signal strength (dB / dBµV). • Sensors: - Internal sensor for general scanning. - Flexible Probe: Included flexible wand/gooseneck sensor for accessing hard-to-reach pipes. • Audio: High-quality Noise Isolating Headphones (industrial grade, >20dB NRR) to block factory noise. Neckband or headband style accepted. • Data Logging: Integrated memory to store measurement points (Leak Database). • Software: Includes PC software to manage survey data, trend leaks, and generate energy reports (estimating cost of leaks). • Accessories: Carrying case, battery charger, and USB cable. Didactic Requirement: A mandatory component is a student guide explaining the energy cost of compressed air leaks (kW loss per cfm/lpm leak) and the physics of ultrasound generation at orifices. | 2 | |
| 3 | Advanced Universal Solar & Heating Controller | Description: Versatile electronic differential temperature controller designed for training on various solar thermal system layouts (e.g., 1-Tank, 2-Tank, East/West Collectors, Heating Support). Technical Specifications: • Inputs: At least 4 temperature sensor inputs (Pt1000 type). • Outputs: At least 2 relay outputs, including capability for PWM / 0-10V control to drive modern High-Efficiency Pumps. • Functions: Pre-programmed hydraulic schemes selectable via menu. Must include functions for: - Standard Solar Charging (Delta-T). - Tank cooling / Holiday mode / Anti-stagnation. - Auxiliary heating request or Solid fuel boiler integration. - Heat Quantity Measurement (via calculation or flow meter input). • Interface: Illuminated graphic display for system visualization. • Connectivity: Data Bus interface (e.g., VBus, CanBus, ModBus, or USB) to connect a data logger or PC adapter. • Accessories: Delivered with 3x Pt1000 sensors (1x High Temperature silicone cable for collector, 2x Standard PVC cable for tank). Didactic Requirement: A mandatory component is a student guide explaining "Hysteresis", "Delta-T Switch-on/Switch-off points", and "Pump Speed Control logic". | 2 | |
| 4 | High-Temperature Oven Profiling Data Logger Kit (6-Channel) | Description: Professional 6-channel temperature data logger enclosed in a Thermal Barrier (Heat Protection Box). Designed to travel inside industrial ovens/furnaces to record temperature profiles (Air & Product temperature) for efficiency audits and process validation. Technical Specifications: • Channels: 6 independent channels for Thermocouples (Type K). • Memory: Capacity for approx. 100,000 to 200,000 readings. • Thermal Barrier: High-grade stainless steel enclosure with high-performance insulation (fiberglass or microporous). - Protection capability: Must withstand oven temperatures (e.g., 250°C for min. 50 minutes) without damaging the electronics. • Measurement Range (Logger): -200°C to +1300°C (Sensor dependent). • Interface: USB C or Micro-USB for data download. • Software: Professional analysis software included (Profiling, Graphing, PDF Reporting, CSV Export). • Sensors (Crucial): Includes 6x High-Temperature K-Type Thermocouples. - Cable: Stainless steel braided or mineral insulated (flexible). - Length: Long probes (approx. 3m - 6m) to reach all corners of the test object. Didactic Requirement: A mandatory component is a student guide explaining "Thermal Profiling" and how to identify "Cold Spots" in an oven which indicate energy losses or quality risks. | 1 |
