Rocket Motor Casing Pressure Test Rig Kit with Arduino Mega + Sensor
Professional Rocket Motor Casing Hydrostatic Pressure Test Rig – Arduino Mega & MPX5700 Safety Interlock System
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Verify the structural integrity of your solid rocket motor casing before a live static fire. This kit equips you with a multi-channel pressure monitoring system that automatically cuts off the hydrostatic pump if any port exceeds a preset threshold, preventing catastrophic failure. The rig uses four MPX5700 pressure transducers to capture real-time pressure data across casing ports, applying the same methodology ISRO uses for motor proof testing.
What You'll Build
Assemble a benchtop test console that reads four MPX5700 analog sensors simultaneously, logs data with timestamp to SD card, displays live pressure curves on a TFT screen, and triggers a relay to disable the pump via the safety interlock—all controlled by an Arduino Mega. The finished unit fits inside a DIN rail enclosure, ready for integration into your test stand.
What You'll Learn
- Configuring MPX5700 sensors for high-pressure fluid measurement with analog signal conditioning
- Implementing multi-channel data acquisition and real-time visualization on a TFT display
- Designing a hardware safety interlock with relay control to protect test operators
- Logging pressure data to microSD with precise RTC timestamps for post-test analysis
- Soldering and assembling a DIN rail-mounted industrial-grade enclosure

Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during sensor calibration?
Scan the QR code to launch the AI companion; it will walk you through offset and gain adjustments for each MPX5700. If you still need help, message us on WhatsApp and a real build advisor will respond within hours.
Can this rig test liquid rocket motor casings too?
Absolutely. The hydrostatic test principle is identical for solid and liquid motor casings. You will need to supply the pump, hoses, and water, but the electronics interface and safety interlock work for any pressure vessel up to the sensor rating.
Does the kit include the hydrostatic pump and high-pressure hoses?
No. This is an electronics and control system kit. You provide the pump, fittings, and test fluid. The relay module can directly switch any 230V AC pump up to 10A through its contacts, or you can use it to drive a contactor for larger pumps.
How do I integrate the safety interlock with my existing pump control system?
The 4-ch relay module has one channel dedicated as the master cut-off. Wire its NC (normally closed) contact in series with your pump power circuit. When any MPX5700 reading exceeds the threshold you set in the Arduino code, the relay de-energizes and breaks the circuit instantly. The AI companion provides wiring diagrams for common configurations.
