Getting Started Understanding Instrument Basics The CS-L Magnetometer Sensor consists of a sensor head and sensor electronics that are interconnected by a cable. This section provides schematics and descriptions for each of these components and their subsystems. Sensor Head The sensor head houses electro-optical detection system. All the parts of the sensor head, including the outside plastic housing, are made of carefully screened nonmagnetic materials. The following figure shows a schematic of the sensor head. 2—2 Figure 1 - Schematic of the sensor head Important: To minimize the static magnetic interference from the electronic components which are slightly magnetic, the sensor head should be kept away from the electronics assembly by the full cable length. The actual measurement of the ambient magnetic field takes place inside the absorption cell which has diameter 22mm, and the length 25mm. The position of the cell's centre is marked by a narrow groove, machined on the outside of the plastic cylindrical housing. The adjacent wider grove is provided to facilitate secure grip for the mounting clamps. The interconnecting cable exits at the right angle on the top end of the sensor head. For properly orienting the sensor head as described in Chapter 4, “Orienting P/N 763701 Rev. 1
