Installing the probe

The Installation process is a series of simple operations:

  1. Selecting the location of the probe.
  2. Installing the support plate.
  3. Installing the probe, control unit, and solar panel

Selecting the location of the probe

Selecting the probeA probe device mounted in the side of a bin to measure the moisture content of aggregate materials such as sand. location is a very important step as you must consider the following:

The probe should be location as much as possible to the front, while also allowing the probe to clear the concrete when at the highest point during a drum revolution.

By placing the probe toward the front of the drum, this will ease its cleaning and help it to accurately measure concrete characteristics with a small concrete loadThe total amount of concrete or asphalt that is being or has been batched for delivery.. At the lowest point during a revolution, the probe must be fully immersed in concrete to give accurate results, as shown in the images below.

When the probe is too close to the blades inside the drum, the workabilityThe consistency of fresh concrete before it sets is called workability. The makeup of a mix is measured using a slump flow test to measure both vertical and horizontal settling. Slump factors in the viscous nature of a mixture and is measured vertically. Spread factors in the flow of the material and is measured horizontally. measurement may be affected and the slumpSlump is defined as the number of inches (or millimeters) concrete will sag, or slump, when a special test cone filled with the concrete is turned upside down and the cone pulled off the concrete. In other markets this is called ‘consistency’. Consistency for concrete can be stated different ways. Examples are: slump, flow, workability. We mostly use ‘slump’. (or spreadThe consistency of fresh concrete before it sets is called workability. The makeup of a mix is measured using a slump flow test to measure both vertical and horizontal settling.

Bad probe placement too close to the front Bad probe placement too far back in the drum

The best results are achieved when the probe is centered between two adjacent spiral blades.

The hatch, depending on its location on the drum, often represents a good place to install the probe mainly because this place is almost always exempt of any blade.

Installing the support plate

To get accurate readings, the probe should be aligned with both axes. Place the magnetic template parallel to the drum’s rotation axis welding lines with designated side toward the chute. Use it to mark the hole.

Keep a safe distance from the drum’s welding and blades.

Installing the probe & control unit

The plate is now used to position the probe and its control unit. Once these components are installed, you'll then also install the solar panel to power the probe.

Note the Bluetooth ID (indicated by a sticker on the control unit) for ulterior registration of the system.
