Allen Bradley 1746-IA16

Specifications Parameters are specified from +20 to +30 °C (+68 to +86 °F) and 100 Hz unless otherwise indicated. Operation outside the specified limits may result in false readings or loss of machine monitoring. Electrical 330400 Sensitivity 10.2 mV/m/s2 (100 mV/g) ±5%. Acceleration range 490 m/s2 (50 g) peak overall acceleration within the 10 Hz to 15 kHz frequency span. Vibration at frequencies above 15 kHz, especially at the transducers resonance will significantly decrease this range. Amplitude Linearity ±1% to 490 m/ s2 (50 g) peak. Broadband Noise Floor (10 Hz to 15 kHz) 0.039 m/s2 (0.004 g) rms. 330425 Sensitivity 2.5 mV/m/s2 (25 mV/g) ±5%. Acceleration Range 735 m/s2 (75 g) peak overall acceleration within the 10 Hz to 15 kHz frequency span. Vibration at frequencies above 15 kHz, especially at the transducer’s resonance, will significantly decrease this range. Amplitude Linearity ±1% to 735 m/s2 (75 g) peak. Broadband Noise Floor (10 Hz to 15 kHz) 0.098 m/s2 (0.01 g) rms. Both Units Frequency Response 10 Hz to 15 kHz (600 cpm to 900,000 cpm) ±3dB; 30 Hz to 10 kHz (1800 cpm to 600,000 cpm) ±10% Temperature Sensitivity -11% to +3% typical over the operating temperature range. Transverse Sensitivity Less than 5% of axial. Mounted Resonant Frequency Greater than 30 kHz. Amplitude of Resonant Peak 20 dB maximum. Base Strain Sensitivity For serial numbers preceded by the letter “G” (including all new sensors 49 mm/s2/mstrain (0.005 g/mstrain) For serial numbers NOT preceded by the letter “G” (shipped prior to April 2004) 980 mm/s2/mstrain (0.100 g/mstrain) without Mounting Base (API adapter); 4.9 mm/s2/mstrain (0.0005 g/mstrain) with Mounting Base (API adapter) supplied with the accelerometer. Bently Nevada recommends installing with the Mounting base to minimize base strain sensitivity for serial numbers NOT preceded by the letter “G”. Maximum cable length 305 metres (1000 ft) with no degradation of signal. Power requirements Input Voltage -24 ± 0.5 Vdc. Bias Current 2 mA nominal. Output Bias Voltage: -8.5 ± 0.5 Vdc. Grounding Case isolated. Environmental Limits 330400 and 330425 Accelerometer Acceleration Transducers Datasheet 2/10 141638 Rev. W Operating and storage temperature -55°C to +121°C (-67°F to +250°F) Shock Survivability 49,050 m/s2 (5000 g) peak, maximum. Relative humidity 100% condensing, non-submerged. Case is hermetically sealed. Magnetic Field Susceptibility <2.21 mm/s2/gauss (225 mg/gauss) [50 gauss, 50-60Hz]. IP Rating Equivalent to an IP 68 (Dust tight and watertight). Please note that this is for the sensor only and does not apply to the cable. Physical Weight (no cable) 99 g (3.5 oz), typical Diameter 23 mm (0.93 in). Height 59 mm (2.3 in), including mounting stud. Connector 3-pin MIL-C-5015 Receptacle 316L stainless steel Mounting Surface 32 minch rms. Mounting Torque 4.1 N·m (3.0 ft·lb). Case Material 316L stainless steel Weight (no cable) 100 g (3.5 oz), typical Mounting Angle Any orientation 330400 and 330425 Accelerometer Acceleration Transducers
