LSM Data Sheet

Product catalog summary

Overview: The LSM Series Accelerometers by Jewell Instruments are designed for high reliability with a 100,000-hour MTBF and a sensing range up to 20g. They are compact, approximately 1 inch cubed, making them suitable for space-constrained applications, particularly in aerospace.

Features & Benefits:

Full range from ±0.5g to ±20.0g.
Filtering capability up to 200 Hz bandwidth with 0.6 damping.
High reliability for satellite applications.
Resolution better than 20 µg at 10g full scale.
Operating temperature range from -55°C to +95°C.

Applications: The accelerometers are used in various applications including satellite nutation sensing, radar leveling, fire control, attitude heading and reference systems, train braking and banking, missile orientation, autopilot systems, train performance testing, wind shear detection systems, Mars Rover, and thermal vacuum chamber testing.

Specifications:

Performance: Input range varies from ±0.5g to ±20.0g with a full range output of ±5.0% FRO. Non-linearity ranges from 0.05% to 0.25% FRO. Scale factor varies from 10.0 V/g to 0.25 V/g. Bias temperature sensitivity ranges from 50 µg/°C to 200 µg/°C.
Electrical: Operates on a nominal input voltage of ±12 to ±18 Vdc. Output impedance ranges from 2.5 to 10.0 Ohms.
Environmental: Operating temperature range is -55°C to +95°C, with a survival range of -65°C to +105°C. Shock resistance is 100g for 11 msec, ½ sine, and it meets MIL-STD 202, Method 112 for sealing.

Ordering Information: Models are available with different part numbers based on the g-range, from LSMP-0.5g to LSMP-20g.
