Applications —
Process Control
Process
Requirement–
A leading tire manufacturer wanted to
measure the flow of water to a rubber mixing machine.
Due to the non-linear
characteristics of rubber, maintaining constant temperature is
critical to the process. The water flow rate is transmitted to the
control room, where it is balanced against RTD temperature
measurements to minimize temperature excursions and optimize water
consumption.

Automotive
Assembly
Process
Requirement–
Automotive chassis are welded together by robots at an automotive
manufacturing plant. To prevent overheating, cooling water is
supplied to arc welders attached to the robots.
- If the cooling water fails, the
arc welders will be damaged due to overheating
- If the cooling water fails
because of a break in the supply or return line, the water will
flood the assembly line floor causing robotically controlled
carts to slip and miss their mark. When this happens the robotic
arc welder will miss their points they are programmed to weld
causing damage and rejection of the chassis and stopping the
assembly process.

| |
| Solution– |
|
| The
Sparling Tigermag |
| Two identically
calibrated Tigermags monitor the cooling water flow to and from
the welders. If there should be a flow variation between the
incoming and outgoing flow, two different preset alarms are
activated. The initial alarm is a warning — the final alarm
alerts the operator to shut down the assembly line. The first
alarm is a warning, the last is a shutdown of the assembly line
until the problem is resolved.
This system has saved the
customer significant time and costs in the form of damage to arc
welders and car chassis. Overall, it has improved the efficiency
of the assembly line.
