The new “PA” generation is a highly-compact table-top analyser. Thanks to its small size and lightweight design, the device can be stored at any place where gas mixtures are processed. The flexible system can be deployed both for random sampling and for permanent monitoring and is used e.g. in the food industry or in welding and cutting applications.
The system measures the carbon dioxide and/or oxygen concentration, depending on the model. When the individually adjustable limit value is reached, the “PA” triggers an alarm and actuates an isolated contact, e.g. for interrupting the gas supply. These devices are virtually indispensable for quality assurance. “Numerous features have even been further optimised for the current model version,” Martin Bender of WITT confirms. “And many new features have been added.”
The new “PA” includes a larger and more informative display in a splashwater-protected housing. The keyboard and the menu structure have also been extended and enable an intuitive operation - even when wearing gloves. Menu functions can be blocked individually for users. The USB interface enables users to import measuring information for external processing from the large internal storage. Software updates can be installed via SD card in an instant.
The sensor system is a key technology of the Germany-based manufacturer: The “PA” performs measurements in 0.1 percent increments quickly and accurately, while consuming significantly less measuring gas as compared to conventional devices - a great advantage when controlling even the smallest food packages. The new electronic system with two pressure transmitters enables a permanent flow rate control, with the pump output being adjusted variably. The best system is useless however, if the metering needle is blocked. The “PA” however detects any blockage of the metering needle and immediately triggers an alarm. The microprocessor-controlled device permanently checks independently, whether all subsystems are functioning properly. An external printer can be actuated via Bluetooth in order to document the measuring results. As an alternative, you can also opt for the “PA” version featuring an integrated thermal printer.
