Model 1510 Vibration Series accelerometers

ETLG Inertial Aerosystems announces a lower cost family of analogue surface mount (LCC) MEMS variable capacitive accelerometers. They offer reliable general purpose vibration measurements at OEM volumes, with excellent long-term stability, across a variety of aerospace, automotive, energy, industrial, oil & gas, and test & measurement applications.

Key features of the 1510

• Excellent long term stability
• Responds to DC and AC Acceleration
• Differential or Single Ended Output
• +5 VDC, 6 mA power (typical)
• -40 to +85°C operation
• Integrated sensor & amplifier
• Nitrogen damped & hermetically sealed
• Serialized

Model 1510 Series incorporates a micromachined variable capacitive sensing element and custom integrated circuit. The accelerometer produces two analogue voltages which vary proportionately according to measured acceleration levels. Series units respond to either AC and DC acceleration, with choice of either +4V differential or 0.5 to 4.5V single ended output. Both outputs read nominally at +2.5 volts at zero acceleration. They are packaged in the familiar 8mm square SMD configuration

Designed by US based Silicon Designs Inc,  Model 1510 Series is both nitrogen damped and hermetically sealed. Two reference voltages, +5.0 and +2.5 volts (nominal), are required. The output scale factor is ratiometric to the +5 VDC 6 mA (typical) reference voltage. Sensitive axis is perpendicular to the bottom of the LCC package. Units are RoHS compliant and can reliably operate over a standard temperature range of -40° to +85°C. As a MEMS-based device, the Model 1510 Series is also insensitive to temperature changes and gradients, with a signal output that is further unaffected by electromagnetic interference, and requiring no warm-up period.

Units are available in 5 standard measurement ranges from ±5 g to ±100 g, with corresponding nominal frequency response from 0 to 600 Hz (±5 g) to 0 to 2500 Hz (±100 g). Low-to-medium sized quantities of the  Model 1510 Series are available for customer shipment. OEM volumes are available in as short as three weeks from receipt of an SDI acknowledged purchase order.
