Miniature Precision Pressure Sensor

For achieving highly accurate pressure measurements in thermodynamic environments

The PCB® Model 115A04 is an extremely accurate, high-temperature, high-pressure charge output sensor suitable for measuring thermodynamic pressure in a wide range of applications such as engine and powertrain development including combustion analysis and other applications that require accurate dynamic pressure measurements.

Wide Amplitude and Frequency Range

This miniature charge output sensor includes naturally stable sensing elements, so it is a highly accurate way to measure dynamic pressure variations over a wide amplitude, temperature and frequency range. It offers a measurement range up to 3,500 psi (241 bar) and is survivable to 752°F (400° C).

Durable and Dependable

The Model 115A04 comes in a miniature M5 package with a one-meter removeable cable. Its stainless steel housing and welded hermetic diaphragm help ensure durability in harsh testing environments.

In addition to traditional gas and diesel engine applications, the new sensor is also used for dynamic pressure testing of small engines, motorcycle and ATV engines, stationary marine equipment, and power-generating engines. It comes with a standard one-meter oil-resistant cable which terminates into a BNC adapter and can be integrated with other manufacturer’s systems and accessories. Each unit is supplied with a dummy plug, thermal baffle and spare o-ring.

Highlights:

  • Highly accurate (with a non-linearity of ≤ 0.3% FS)
  • Measurement range up to 3,500 psi (241 bar)
  • High sensitivity – to 1.40 pC/psi (20.3 pC/bar)
  • Measures accurate pressure in thermodynamic environments (Thermodynamic Error ΔP max <1%)
  • Durable Stainless Steel Housing

Applications:

  • Dynamic Pressure Measurements
  • Thermodynamic Measurements
