Accelerometers and Pressure Sensors Purpose Built for Cryogenic Applications

PCB's cryogenic sensors are specifically designed and tested for extremely low temperature environments.

Material selection and construction techniques have been extensively vetted to ensure compatibility with, and survivability in, cryogenic temperatures. These design decisions reduce stress on internal components that could cause premature failure.

Accelerometers

PCB offers two types of cryogenic accelerometers, ICP® and charge output, which offer unique advantages/disadvantages for cryogenic testing.

ICP® (or IEPE) accelerometers have built in electronic circuitry for conditioning the signal that is generated by the sensing element (pC/EU) into a low impedance voltage signal directly out of the sensor (mV/EU). These sensors require excitation power from signal conditioning electronics in order for an output signal to be provided (18 30V DC, 2 20 mA). Operating temperatures range from: -320° to +356° F (-196° to 180° C).

For safety reasons our ICP® accelerometers, temperature coefficient is measured in liquid nitrogen at -320° F (-196° C), which is our stated operating temperature for our ICP® accelerometers. Model 351A15 was successfully qualified by an outside lab to lower temperatures, e.g. in the presence of liquid helium during structural testing of rocket boosters (-420° F/ -251° C), which is our stated survival temperature.

Charge output accelerometers directly output the electrical signal that is generated by the sensing element. They are sometimes referred to as self-generating and do not require any external excitation power. An external charge amp is required to condition the output into a voltage signal, and the advantage of this is that we can extend operating temperatures ranges from -452° to 350° F (-269° to 177° C).

Pressure Sensors

PCB's cryogenic sensor series 102B1 feature ground isolation and low operating temperature capability, -320 °F (-196 °C), ensuring reliable operation and accurate measurements. We also offer our model 112B05 charge output pressure sensor, which is unique for its ability to withstand both extreme heat and cold from -400 to +500 °F (-240 to +260 °C).
