In case you missed May’s webinar with Sartorius Intec on load cells, we’ve put together some of the key points:
Let’s start with the most common weighing element: the strain gauge load cell.
A strain gauge load cell can be found in bench platforms, floor scales, and in some cases, tank and hopper systems. It is the most common load cell used in the weighing industry.
The most common electrical strain gauges are thin, rectangular strips of foil with maze-like wiring patterns on them, leading to a couple of electrical cables. You stick the foil onto the material you are measuring and wire the cables up to your computer or monitoring circuit.
In case you missed last month’s webinar with Jordan Valve on back pressure regulators, we’ve put together some of the key points.
The Control Loop:
Sensing element: measures the process variable being controlled, and send an output to the controlling instrument
Controlling instrument: calculates the error (difference in signal from sensing element and the desired setpoint) and sends corrective signal to final control element
Final control element: varies the flow to change the controlled variable to the required setpoint
Let’s start with the basics.
What is a pressure regulator?
A pressure regulator is a normally-open valve used to regulate or reduce undesirable, high upstream pressure. The pressure regulator must be installed at the START of a system, before any pressure-sensitive equipment.
The valve is held open by springs, and a screw that sets spring force. When outlet pressure exceeds the setpoint, the valve will close. When the valve closes, pressure is reduced downstream.
In case you missed last week’s webinar on belt scales, we’ve put together some of the key points:
Conveyor Considerations: Use strings to align the scale with the idlers on each side of the weigh bridge.
- Each idler should be parallel to the idler next to it.
- The center of each idler should be in line with the idler next to it.
- Each idler should not be higher or lower than the idler next to it.
- Minimum of 2, preferred 3, idlers on each side of the weigh bridge
