Miniature accelerometer operates to 180°

23 September 2015

According to PCB Piezotronic, its new triaxial ICP accelerometer is the world’s smallest to be capable of operation to 180°C.

PCB Model HT356B01 can withstand operating temperatures to 180°C and uses the same 6.35mm cube titanium housing as its Model 356A01 predecessor.


The hermetically sealed accelerometer features improved strain relief with a larger, stronger crimp tube and is compatible with an ICP (IEPE) signal conditioner or readout device. Its high temperature capability makes it suitable for use in a wide range of applications including gas turbine component qualification, engine vibration measurements – including high performance engines such as F1 – structural vibration, environmental stress screening, noise vibration and harshness and high temperature vibration measurements where there are space restrictions.

Features include 5mV/g sensitivity, measurement range of ±1000g peak and overload limit – 10,000g. An integral 1.5m cable to 4-pin connector and supplied mating cable assembly terminating in BNC plugs complete the Model HT356B01 package.


Technical specifications encompass frequency range of 2 to 8000Hz (y and z axes) and 2 to 5000Hz (x axis) all ±5%, frequency range on x axis above 8kHz at ±1dB, resonant frequency above 50kHz and weight without cable of 1.0grams.


The Model HT356B01 miniature triaxial accelerometer is available via PCB Piezotronics’ 'On Your desk in Five Days' stock delivery programme and is CE marked.
