The Jewell LCF-300 Series flexure suspension servo fluid damped inclinometer is a ±1° to ±90° device designed for applications where high levels of shock and vibration are present. LCF-300 units are characterized by excellent turn on repeatability and very low hysteresis. It is available in three different versions (D, L, or S), varying input and output, and with either a 6 pin connector or a pin-terminal option in order to meet your specific needs.
