Soil probe device and method of making same
First Claim
1. A probe for a soil media measuring device, the probe comprising:
- a housing, the housing having a receiving end;
a tip assembly configured to mount in the receiving end, the tip assembly including;
a tip, the tip having a first end distal to the housing, wherein the tip assembly and the housing are separately formed and configured to be inserted within the soil media;
a plurality of electrodes disposed in the tip at locations spaced at least substantially equally from the first end of the tip and at least substantially equally around the tip, the electrodes enabling a signal indicative of a property of the soil media to be generated with the device;
a temperature sensing element that enables the device to provide temperature compensation; and
wherein the temperature sensing element is disposed within an aperture formed in the tip and is spaced apart at least substantially equally with the electrodes from the end of the tip.

Abstract
A device for measuring one or more different properties of soil or a soil-related substance is provided. The device includes a probe that is inserted into the soil or soil-related substance. The probe includes a tip. The tip is electrically insulative and defines apertures. Electrodes are fitted into the apertures. The tip and electrodes are machined together to have a desired shape that is suitable for insertion into a sample. A printed circuit board (“PCB”) is located inside the probe. The electrodes are soldered directly to the PCB in one embodiment. A temperature sensing element is also located in the tip, near the electrodes, and is connected electrically to the PCB.
