Sonic Meter Specifications
Pressure reading: 0-120 e4 Pascals, error < 3.0%, over the working range.
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.
Accuracy (Sonic AO): The Sonic Meter uses a 12bit ADC to digitize the analog intensity signal coming from the probe’s transducer. The accuracy of the ultrasonic meter is within +0.03 e4Pascals.
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 ultrasonic Sonic Meter consumes current at a rate of 130mA/hour. The NiMH batteries are rated at 2500mAH. With continuous use, the run time is approximately 14 hours.
