PCB®’s measurement expertise for satellites and their components includes four main areas: vibration testing in thermal vacuum conditions, force limited vibration (FLV) testing, pyroshock testing for stage separation, and launch-induced acoustic stress testing.
Low outgassing accelerometers and cables
PCB’s satellite testing sensors are built for exposure to the high vacuum level of a space environment. Since most satellites are instrumented during assembly, our satellite acceleration sensors and cables can be cycled through thermal vacuum chambers, used for subsequent vibration testing, and used during flight without the risk of releasing contaminants from outgassing.
Mechanically isolated, electrically filtered pyroshock accelerometers
Series 350 ICP® sensors are ideal for measuring extreme pyroshock events such as those found in metal-to-metal impacts, explosive bolts, impact tools, and stage separation testing. This mechanical isolation, coupled with an internal two-pole electrical filter built into the ICP® circuitry, tailors the overall accelerometer response to assure data quality to frequencies as high as 10 kHz.
Depending on the specific model, accelerations up to 100 kg can be successfully measured. With their internal elastomeric isolation materials, these modern designs are verified through calibration to remain linear to full scale and enable these piezoelectric accelerometers to operate in increasingly severe acceleration environments.
Force limited vibration (FLV) test systems
PCB’s FLV test systems are designed to limit the reaction force between the shaker and unit under test in random vibration testing. The use of piezoelectric, three-component force sensors facilitates easy and accurate measurement of input force.
Prepolarized ICP® microphones
PCB’s prepolarized ICP® microphones are used for acoustic stress testing in either reverberant acoustic test chambers or with a direct field acoustic test system, outdoors on a launch pad with water resistant capabilities, or during rocket flight to record high dB level noise from rocket engines and airflow.
