Miniature Accelerometers P Series
- Manufacturer: Monitran
- Category: Accelerometers and Vibration Sensors, SENSORS, Without amplification
The P Series (models P100, P100T, and P05) are miniature load-out accelerometers for testing applications. They are passive, with no internal amplification electronics, and operate up to 250 °C. The mass is 7 g (P05) and 30 g (P100/P100T), which reduces mass loading error on thin surfaces, turbine blades, and high-speed automotive components.
Versions: The P100 has a side entry cable, and the P100T has a top entry cable. The piezoelectric assembly is identical, and the sensitivity is 20 pC/g; the difference is the connector orientation.
- Nominal load sensitivity: 5 pC/g (P05), 20 pC/g (P100/P100T), 50 pC/g (P50), 1100 pC/g (P1100).
- Dynamic range: ±2,000 g (P05), ±1,000 g (P50), ±800 g (P100), ±100 g (P1100).
- Frequency response: 1 Hz to 30 kHz (P05/P100) and 1 Hz to 10 kHz (P50/P1100).
- Mounted resonance: 45 kHz (P05) and 30 kHz (P100).
- Cross-sectional sensitivity: less than 5%.
- Amplitude linearity: ±1% (P100) and ±5% (P05).
- Nominal capacitance: 300 pF (P05) and 450 pF (P100).
- Operating temperature: -55 °C to +250 °C.
- Weight: 7g (P05), 30g (P100/P100T), 35g (P50), 250g (P1100).
- Microdot coaxial connector; 10-32 UNF (P05) male and 10-32 UNF (P100) female mounting; mounting torque 3 Nm.
- Stainless steel housing; IP65 / IP66 protection rating depending on the model.
- Conditioning required: load amplifier (e.g., MTN/CA003).
Technical FAQs
1. Can they be connected directly to a standard oscilloscope or vibration analyzer?
No. As they are passive load output sensors, they do not have preamplification (No Amp). An external load amplifier (e.g., the CA003 module) is required to convert the load signal (pC/g) into a proportional analog voltage (mV/g).
2. Are there any internal differences between the P100 and P100T models?
No. The piezoelectric assembly is identical, with the same sensitivity of 20pC/g. The difference is the connector orientation.
3. What wiring does the P Series require?
Low triboelectric noise coaxial cables, so that movement or bending of the cable does not induce parasitic signals in the measurement.
