Overview: The Jewell LCA-165-R Series accelerometers are designed for high accuracy and durability in railway applications. They are recognized as the highest repeatability sensors in their class globally and comply with CENELEC/AREMA standards.

Specifications: The accelerometers offer a full range of ±0.5g to ±2.0g, with filtering options and a high-level ± Vdc output. They can withstand shocks up to 100g and have exceptional bias characteristics.

Applications: These sensors are used in rail monitoring and testing, automated train controls, train performance testing, and acceleration/deceleration control.

Performance Specifications: The accelerometers have a nonlinearity of 0.05% FRO max, a scale factor temperature sensitivity of 180 PPM/°C max, and a natural frequency of 60 Hz nominal. They also feature a transverse axis misalignment of 1.0° max and a bias temperature sensitivity of 100 µg/°C max.

Electrical Specifications: The input voltage range is ±12 to ±18 VDC, with a maximum input current of 25 mA. The output impedance is 1 Ohm nominal, and the noise level is 0.005 Vrms max.

Environmental Specifications: The operating temperature range is -55° to +85°C, and the storage temperature range is -60° to +90°C. The sensors are sealed according to MIL-STD-202, Mtd. 112 standards.

Ordering Information: The accelerometers are available in different models based on the input range (±0.5g, ±1g, ±2g, ±5g). Accessories include connector cables of various lengths, with custom lengths available upon request.

Compliance: The sensors meet standards such as CENELEC EN 55022:2010, CENELEC EN 50155:2007, CENELEC EN 61000-4-8:2010, and AREMA PART 11.5.1.
