Sonic Meter Specifications
Bandwidth: up to 500kHz
Pressure reading accuracy: 0-120e4Pa, acceptance error < 5% error over working range.
Resolution (Sonic AO): The Sonic Meter Sonic AO uses a 12bit ADC to digitize the analog signal coming from the probe’s transducer. Resolution of the meter is +0.03e4Pa.
Temperature Operating Range: -65 to 250 F or –55 to 120 C
Performance (Sonic AO): Real time reading samples force/area intensity every 50msec. Averaged meter reading can sample 0-40 pressure intensity samples at intervals of 10msec to 99.99sec.
Probe: Stainless steel, hermetically sealed ultrasonic piezo sensing element. The probe diameter is 8mm (.312″) and the length is 38cm (15″) for the Sonic AO and 30cm (12″) for the Sonic Check.
Housing: Anodized aluminum
I/O (Sonic AO): Inputs via membrane keypad, output via 4X20 LCD character display
Control inputs (Sonic AO): high/low limits, probe setup
Battery life (hours): The Sonic Meter Sonic AO consumes current at a rate 150mA/hour. The NiMH batteries are rated at 800 to 1000mAh. For continuous use, the meter will run approximately 5 hours before batteries will need to be recharged.
