A d₃₃ meter directly measures the piezoelectric constant (d₃₃), a key parameter that quantifies how much electric charge ⚡ is generated per unit of mechanical stress applied along the same axis.
It is a measure of how effectively a piezoelectric material converts electrical energy 🔋 into mechanical energy ⚙️ (or vice versa).
A higher d₃₃ value indicates greater efficiency in this energy conversion, leading to larger strains from an electric field or stronger electric fields from stress.
✅ It is essential for designing and evaluating piezoelectric sensors and motors, where a higher d₃₃ means greater sensitivity and responsiveness.
🔍 How d33 meter Works — The Measurement Process
1️⃣ Sample Placement: The specimen is placed between two probes (corn or flat types supplied).
2️⃣ Force Application: A consistent force at 110 Hz is applied while measuring.
3️⃣ Data Readout: The device displays the d₃₃ value and polarity.
4️⃣ Calibration Option: Adjust via zero-point or calibration screws to ensure accuracy 🔧 or average out polarity differences (measure once, rotate sample 180°, average values).
💡 Our two Berlincourt d33 meter meter models PKD3-2000 and PKD3-4000 are designed to measure d₃₃ of polymer PVDF, PVDF-TrFE, or piezoelectric ceramic materials.
📏 Two measurement ranges: 10 to 2,000pC/N, or 10 to 7000pC/N
⚖️ Force: 0.25N
⏱️ Frequency: 110 Hz
It works great with both piezo ceramics and polymers such as PVDF, PVDF-TrFE, PLLA, or polymer nanocomposites. Also works for thin film on conductive substrate (silicon wafer with electrode) such as AlN aluminium nitride.
📌 This unit comes with Poly-K static force sensor to improve measurement accuracy and reproducibility.
🛠️ Our d₃₃ meters can be offered in four different configurations depending on the specific application:
1️⃣ Piezo d₃₃ meter + static force sensor
2️⃣ Piezo d₃₃ meter + static force sensor + 🔥 300°C temperature chamber (manual + digital controller)
3️⃣ Piezo d₃₃ meter + static force sensor + 🔥 600°C temperature chamber (manual + digital controller)
4️⃣ 💻 Upgrade to software control, including a Windows 11 laptop — automatic temperature control, ramp/isothermal measurement, and real-time data recording 📊.
✨ Reliable, accurate, and versatile — designed for cutting-edge piezoelectric research and applications.
