The Dytran 7503D2 is a triaxial DC accelerometer with a ±2 g input range, designed for low-level acceleration measurements in zero-to-medium frequency applications. It features differential output, hermetic sealing, and a titanium alloy housing weighing 38 grams. The unit has a frequency response of ±5% from 0 to 400 Hz and ±3 dB to 800 Hz, with a resonant frequency exceeding 2000 Hz. Sensitivity is 2000 mV/g (differential), and output noise is 10.5 μg/√Hz. It operates on +6 to +33 VDC, with a common mode voltage of 2.5 VDC and maximum power consumption of 35 mA. The device is rated for operating temperatures from -55 °C to +125 °C and withstands shocks up to 2000 g peak. Accessories include a 9-pin 5/16-32 UNEF-2A connector, calibration certificate, mounting studs, screws, and flat washers.
Dytran series 7503 is a high precision triaxial variable capacitance (VC) accelerometer available in various g ranges for the X, Y and Z axes. The accelerometer combines an integrated VC accelerometer chip with high drive, low impedance buffer and differential output for low level acceleration measurements. Tailored for zero-to-medium frequency applications, the Dytran series 7503 contains hermetically sealed MEMS capacitive sensing elements, a custom integrated circuit amplifier and low noise electronics, housed in a lightweight titanium case.
