The Dytran 7500A1 is a differential variable capacitance accelerometer with a ±2 g input range, 0 to 400 Hz frequency response (±3 dB), and 1,000 mV/g sensitivity. It features a hermetic seal, titanium alloy housing, and a 4-pin 1/4-28 UNF-2A connector. The unit weighs 19 grams and includes two mounting screws: model 6868 (4-40 UNC) and 6688 (M3×0.5). Maximum shock rating is 2000 g pk, operating temperature range is -55 to +125 °C, and power supply is +9 to +32 VDC. Output noise is 12 µg RMS/√Hz, linearity is ±0.5% of span, and transverse sensitivity is ≤3%. The accelerometer provides DC response and operates with a common mode voltage of 2.45 VDC.
The Dytran series 7500 is a high precision single axis variable capacitance (VC) accelerometer available in various g ranges and in an airborne version. This high performance accelerometer combines an integrated VC accelerometer chip with high drive, low impedance buffer for low level acceleration measurements. Tailored for zero-to-medium frequency applications. This module contains a MEMS capacitive sensing element, a custom integrated circuit amplifier, low noise electronics and differential output, with a 4-pin 1/4-28 radial connector and various mounting capabilities. Units are hermetically sealed for reliable operation in high humidity and dirty environments.
