For measuring the molten metal level in melting and holding furnaces, intermediate vessels, channels and launders.
Inductive measuring systems – withstanding up to 800°C; suitable for aluminium (Al), magnesium (Mg), lead (Pb), tin (Sn), zinc (Zn) and copper (Cu)*. Other materials are available on request.
Inductive level measuring systems are used to regulate, control or measure the molten metal level in melting and holding furnaces, intermediate vessels, channels and launders. The measuring systems are available in submersible versions and non-contact versions.
The submersible probes (CLP) from Precimeter GmbH are a high-tech product. They work in the immersed condition with an appropriate protective tube at a melt temperature of up to 800°C and can therefore also be used in closed systems without forced air cooling.
With an gas tight adapter available from Precimeter GmbH, the probes can also be used in closed systems with low pressure castings. Only the best quality materials are used, combined with a good quality assurance system. Each probe is tested before delivery and the results are documented.
The “continuous immersion probe” is a system that directly registers the exact level in the melt through a protective tube. Standard lengths are up to a meter. Further lengths are possible.
The continuous (dual) level probe was developed in order to be able to measure two superimposed levels (e.g. magnesium/salt, aluminium/salt). This application is typical in the electrolysis of primary metal. This submersible probe version also needs an appropriate protective tube.
This contact less measuring probe (PLP) is made for smaller measuring ranges. The measuring range depends on the diameter of the probe. For the standard probe with a probe diameter of 115 mm, a measuring range of 100 mm is achieved. A major advantage is remote operation in relation to the melt. For extreme applications in which heavy splashing cannot be ruled out, the probe can be protected with a monalite protection hood.
The probes can withstand up to 800°C and can also be used in closed systems without forced air cooling. They must not however come into contact with an open fire, e.g. burners, since the operating temperature of the probe can easily be exceeded as a result.
This special probe (PLPR) is used with ladle robots, which automatically extract molten metal from holding furnaces or crucibles. Avoid problems with conventional contact probes.
- no contact with the melt
- no oxide adherence
- no corrosion
- exact reference starting point
The light version of the ring probe was developed to measure the melt inside a ceramic riser tube in low-pressure casting systems. The ring probe is pushed over the tubing, so that the injection process can be started with rising melt from a preadjusted reference point.
The heavy version of the ring probe replaces the connection between the holding furnace and mould (upper tool part) for low pressure pouring. During the casting process, the melt rises in a tube into the ring probe area. The casting process can be started from a preadjusted reference point.
