Abstract
A seismic sensor assembly can include a housing that defines a longitudinal axis; a sensor; sensor circuitry operatively coupled to the sensor; and overvoltage protection circuitry electrically coupled to the housing.
Claims20
A system, comprising:
- a first circuitry board comprising seismic sensor circuitry mounted to an insert configured to couple to a housing;
- a second circuitry board coupled to the first circuitry board, the second circuitry board comprising overvoltage protection circuitry configured to arrest a first portion of energy associated with one or more overvoltage transients to a ground via a first pathway;
- and
- a ground shield configured to:
- couple to the housing and the second circuitry board;
- and
- route a second portion of the energy different from the first portion of the energy to the ground via a second pathway.
4 more elements
An overvoltage protection kit comprising:
- a circuitry board comprising seismic sensor circuitry and configured to couple to a sensor assembly comprising a housing;
- overvoltage protection circuitry disposed on the circuitry board and configured to arrest a first portion of energy associated with one or more overvoltage transients to a ground via a first path;
- and
- a ground shield coupled to the housing, wherein the ground shield is configured to route a second portion of the energy different from the first portion of the energy to the ground via a second path.
1 more element
A method comprising:
- disposing a ground shield inside a housing;
- disposing seismic sensor circuitry on a circuitry board of an insert configured to couple to the housing;
- disposing overvoltage protection circuitry on the circuitry board;
- and
- coupling the insert to the housing to:
- form a first pathway including the overvoltage protection circuitry and configured to arrest a first portion of energy associated with one or more overvoltage transients to a ground;
- and
- form a second pathway including the ground shield and configured to route a second portion of the energy different from the first portion of the energy to the ground.
