PCB introduces UHT-12 series of miniature accelerometers

July 27, 2017 - PCB's UHT-12 miniature accelerometer was designed for applications that demand minimal sensitivity change across a wide temperature range.  Model 320C53 features a sensitivity of 1 mV/g to complement the Model 320C52 sensitivity of 10 mV/g. Both models feature a UHT-12 sensing element which provides a stable sensitivity over large thermal shifts.

These sensors weigh 1.85 grams with a size of 9.6 mm x 17.3 mm. They are hermetically sealed in a rugged titanium housing and feature easy to install thru-hole mounting. The accelerometers attach to test structures with an insulated mounting screw.

Both models have an operating temperature range of -100 to +325 °F (-73 to +163 °C).  Model 320C52 has a frequency range from 1 to 10 kHz (+/- 5%) and Model 320C53 has a frequency range from 1 to 5,000 Hz (+/- 5%). A single pole low pass filter, with a corner frequency set to ≥20 kHz, is incorporated into each model which reduces the potential for saturation or clipping. These features make them sutiable for general flight testing, HALT/HASS/ESS with high random vibration input, and automotive powertrain vibration testing.

Built-in ICP microelectronics provide an output signal capable of being transmitted over cable lengths of hundreds of feet. Any ICP signal conditioner or data acquisition system that incorporates an ICP constant current excitation can be used to power the accelerometers.
