Functional Test - Level Sensors

Universal OTP Functional Test System for the Production of Level and Fluid Sensors

Application Description

Multifunctional function tester with parallel test function based on the LXinstruments OTP2 system platform. The system is used for assembly, final test and calibration of liquid and level sensors for commercial vehicles, construction machinery and shipbuilding in a high mix / medium volume environment.

The system supports 5-fold asynchronous simultaneous testing of different assemblies. It has been universally designed as a platform to replace various existing test benches and to create a future-oriented basis for new test applications. Critical hardware such as multimeters and power supply modules exist for parallel use for each test station. The switching matrix can be used in 5 individual matrices or as a combined switching matrix to cover more complex test applications with the same system.

The systems are completely based on the LXinstruments Software Suite.

Special Features

The system is able to execute 5 asynchronous test sequences in parallel on one control computer. The user interface has been extended to visualize all 5 sequences simultaneously.

Customer-specific Software

The TSCOE user interface has been enhanced for simultaneous visualization of all 5 processes. All product-related test results and data measured during calibration are managed in a relational database (MySQL).

With the open database interface linking to the customer’s ERP system was intended on the part of the customer. The database interfaces were extended to enable flexible storage of product properties and other product data, so that a very convenient integration into the customer’s process landscape became possible.
