Beverage keg cleaning process control

A wireless datalogger with current loop inputs has been developed for CHEOPS spol. s.r.o. which specializes in the beverage industry. To ensure barrel cleaning process quality, internal temperature, pressure and liquid levels need to be measured.

The Wireless Datalogger Current Loop Module (WDL-CL) is capable of logging inputs as well as powering four current loop sensors through standard M12 connectors. The WDL-CL module with integrated accumulator is designed to withstand high temperatures and humid environments (IP67 rated). The user software provides easy and intuitive way of starting the logging process, to show the measured values, adjust the measurement units. The WDL-CL is also able to operate without user software control.

Air-flow measurement in cooling channels of el. machine

Siemens Electric Machines s.r.o. in Drasov deals with the development and production of large electric machines. To verify the efficiency and uniformity of electric machine ventilation, an instrument for airflow measurement, custom made by ADWITECH system s.r.o., was used.

These small wireless modules can be placed in the locations that are not accessible using standard measuring systems. Easy installation without a need to perform any modifications in the   machine has made it possible to quickly assemble and disassemble the entire system directly in the testing room. With an internal battery and wireless communication, the system can be used without cabling, which allows you to carry out measurements on a hermetically sealed machine. The module can also be mounted on the moving parts of the machine to determine the flow of air, e.g. in rotor cooling

Continuous torque measurement on pinion gear

For company Projekt HTL s.r.o was wireless telemetry installed on a gearbox pinion, which turns electric arc ferroalloy furnace. WSM-2 measurement unit was installed on a rotational part and wirelessly powered via induction power coupling to continuously monitor the drive torque. Signal is wirelessly transmitted to nearby distribution box and converted to an analog signal for the control room.

Usage of strain gauge measurement enables user to determine torque without the need to make any mechanical modification.

Concrete sample storage controller

The device developed for Labtechnic - CEM s.r.o. was designed to replace an obsolete control system for the control of humidity cabinets and basins used to store concrete samples.

The new system with touch screen display allows control of status, process variables and parameter setting of two independent PID controllers. An integrated web-server is used for remote access with full control of the system, and user account management is implemented for advanced security. Variable records are double backed up and can also be automatically backed up to remote storage. All power electronics and sensor elements of the previous system have also been replaced.

Mini Cooper

A WTM-4 module was used to verify the operating conditions of the Mini Cooper combustion engine to accurately and instantly measure the temperature of oil and coolant for different driving styles.

The module transmitted the values directly to the driver's cab in without the use of cabling, making it easier to install.

The measurement results were used to set the thermostat so that the oil temperature is within the optimum range. Subsequently, a small display with a receiver for permanent monitoring of values was installed in the cabin.
