The model 2240 accelerometer is a hermetically sealed version of the model 2220. This rugged module combines an integrated model 1221L accelerometer with high drive, low impedance buffering for measuring acceleration in commercial/industrial environments. It is tailored for zero to medium frequency instrumentation applications. The titanium case is sealed using a laser welding process and is easily mounted via two #4 (or M3) screws. On-board regulation is provided to minimize the effects of supply voltage variation. It is relatively insensitive to temperature changes and gradients. A model 2240-CAB cable, sold separately (see order information above), connects via a miniature 4-pin screw-on connector. The cable's shield is electrically connected to the titanium case while the ground (GND) wire is isolated from the case. An initial calibration sheet (2240-CAL) is included and periodic calibration checking is available.
