Silicon Piezoresistive Pressure Sensor (static pressure available)

YMC 621P series silicon piezoresistive pressure sensors are assembled with a high-performance, highly reliable silicone piezoresistive oil-filled core.

YMC 621P series silicon piezoresistive pressure sensors are assembled with a high-performance, highly reliable silicone piezoresistive oil-filled core. The pressure interface and shell are stainless steel and the laser-welded seal gives good corrosion resistance. The sensor is temperature compensated over a wide temperature range to hold its technical specification, and is widely used in demanding pressure measurement applications. Unlike a piezoelectric pressure sensor, it measures static pressure.

Typical applications

• Static and dynamic process pressure measurement
• Hydraulic and pneumatic systems
• Corrosive and high-demand environments

Main parameters

• Power supply — 5 ~ 24 VDC
• Operating current — ≤20 mA
• Measuring range — 0 kPa ~ 7 kPa … 100 MPa
• Working / compensating temperature — -40 °C ~ +85 °C
• Combined accuracy — ≤±1 % F.S.
• Long-term stability — ±0.2 % FS / year
• Response time (10% ~ 90%) — <1 ms
• Insulation resistance — 100 MΩ @ 50 VDC
• Pressure mode — Gauge, absolute and sealed gauge pressure
