Why Moisture Gauges are Important
If you search on moisture sensor and gauges online, there are varying results from soil moisture sensors, to wood moisture sensors and humidity sensors. In this article, we will talk about the different types of moisture gauges and sensors, its uses and benefits. We will learn the best qualities of the best moisture sensors and gauges offered in the market today.
In measuring soil moisture, moisture sensors and gauges measure the soil’s volumetric water content by indirectly using other properties of soil like dielectric constant, electrical resistance, or neutrons interaction which are considered proxy for the soil’s moisture content. It is crucial that these proxy should be well calibrated with soil moisture, and this depends on the soil type, electric conductivity or temperature. For remote sensing in agriculture and hydrology, the soil moisture affects reflected microwave radiation, and gardeners and farmers use portable instruments for measuring soil moisture. Soil water potential can be measured using sensors such as tensiometers and gypsum blocks.
In order for you to know whether a wood is stable to use or not, it is important that you know its moisture content. The two kinds of wood moisture meters are pin and pinless moisture meters, wherein both types measure the effect of moisture on an electromagnetic field (pinless) or an electromagnetic current (pin). Pinless meters are portable that it can be taken into the lumberyard for testing the wood before buying it, and it can scan an entire board without putting holes on it. Pin meters need to be in contact with the wood, and it can take readings no matter what the wood size, shape and degree of roughness it possess. For thick lumber or woods, pin meters or pin moisture sensors allow usage of remote probes or nails for pin meters or pin sensors, which can be driven at the center of a thick lumber for core wood moisture readings that cannot be reached by pinless meters.
The important features you need to consider when buying moisture sensors and gauges are the pin length, moisture content range, minimum sample size, displays, and built-in temperature correction and built-in species. The rule of the thumb is you need a longer pin length for thicker board or wood which is 1/4 of its thickness, and this applies for even moisture gradient where the surface is drier compared to its core. There are four types of displays which are analog, digital LCD, digital LED and LED.
