How To Choose Inclinometers For Sale

By Mattie MacDonald


Measurement of depression and elevation of an item with regard to gravity is done using a device called an inclinometer. The device also measures angles of slope, also known as tilt. The instrument is known by many other names like slope indicator and tilt meter. The instrument gives measurements for both negative and positive tilts. Measurements are given in three commonly known units, that is, percent, degrees, and topo.

Currently, the number of types of tilt indicators available on the market is very high. As such, one should be equipped with knowledge about them before setting out to make a purchase. There are features and capabilities that one needs to check in Inclinometers for sale before buying to avoid losses. Casings and sealing, sensor technology, resolution, accuracy, interference, parts, measuring range, and functionality are among the factors to consider.

The resolution and accuracy of tilt meters refer to the same aspect. The device bought should have a high resolution to serve the purpose the device is acquired for. Accuracy chosen should be dictated by use of the gadget. Most accurate devices have revolutions of about 0.0001 degrees. Accuracy is determined by various factors such as hysteresis, temperature drifts, sensitivity, sensor linearity, and zero offset among others.

Slopes are measured by generating an artificial horizon. After the artificial horizon is generated, measurements of angular tilt are then measured with respect to the horizon. Accuracy and range of measurements is highly influenced by sensor technology. Sensor technology should therefore be considered when choosing a device by checking the number of axes and tilt angle range of a device. Modern devices use a variety of technologies including accelerometer, pendulum, electrolytic, liquid capacitative, and gas bubble in liquid.

One must also give special attention to the casing that comes with the device. An inclinometer casing refers to a special purpose pipe that is used for inclinometer installations. Normally it does three major functions. First, it conforms to movements in the ground surrounding the device and also controls how the probe gets oriented. Controlling probe orientation is done through internal grooves. Lastly, access for the probe is maintained by the casing. This allows the instrument to obtain subsurface measurements.

Additionally, one should consider coupling style, shape of groove, and diameter of casings in an instrument before buying. Wider diameters in casings is preferable because it offers more durability. Durability is higher in larger diameters because access to probe is prevented by accommodating more deformation. Diameters normally come as 85 mm, 70 mm, and 45 mm. All applications can be served using gadgets that are 85 mm in diameter.

Accuracy of readings in tilt meters is directly dependent on quality of groove in casings. Grooves that offer a regular and flat surface for wheels are the best to buy. Grooves should have greater width than the wheels. This is to allow sideway movements. Narrow grooves degrade readings.

QC, CPI, EPIC, shear wire, and standard are some of the casings to pick from. QC casings are more popular than the others. It is preferred by most people due to its high precision in measurements.
