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.

Exceptional Service

We offer world-class customer service, provided 24 hours a day, so when you call any time of the day or night, you can speak with a knowledgeable person. As with all PCB® instrumentation, our precision pressure sensors are complemented with toll-free applications assistance and are backed by our no risk policy that guarantees your satisfaction or your money back.

PCB's single axis and three axis (triaxial) accelerometer configuration parameters include sensitivity, temperature, frequency response, amplitude response, form factor and lead wire grounding. Accelerometers are critical for evaluating proper performance of equipment or structures. Such applications usually require proof of calibration of the entire measurement system from the sensor through to the final output. PCB calibrates all products traceable to NIST and includes a calibration certificate with each sensor shipped.

The most commonly used technology is ICP® accelerometers. These sensors require ICP® Power supplied. Most modern data acquisition, digital control, and portable data systems provide ICP sensor power. ICP Sensors can be referred to as Voltage Mode output sensors. Our PE sensors can be referred to as Charge Mode output sensors. Each directional axis measured requires one channel of the data system or signal conditioner.

Accelerometers can be referred to as accelerometer, accelerometers, accels or accel or the industrial community may refer to them as vib sensor or vib probe. Lifetime Warranty is standard with our Platinum Products offerings.
