[0066] Example 3:

[0067] Based on Example 1 or Example 2, in this example:

[0068] The instrument end cap 1 and instrument housing 2 are made of polycarbonate (PC) engineering plastic, which has advantages such as light weight, high strength, corrosion resistance, and temperature shock resistance. It is more conducive to the needs of miniaturization and lightweighting, and is not easily damaged in the collisions and drops commonly encountered in field use.

The power management board 6 and the acquisition main control board 7 are both connected to the flat-cut groove with screws.

[0071] The top-level communication board 8 is equipped with a Bluetooth module and a GNSS positioning and timing module to achieve wireless communication and ensure signal quality.

It maintains excellent elastic damping performance in high and low temperature environments, making it very suitable for the field use of instruments. Similarly, there are many types of damping materials that can be selected. Silicone rubber is just a preferred high-performance and cost-effective material, and its practical application is not limited to this.

[0073] The end face sealing groove 13 and side sealing groove 12 of the instrument end cover 1 are fitted with silicone rubber sealing rings. After applying lubricant, they are more convenient to connect and install with the instrument housing 2.
