The WIKA 111.31 Bourdon Tube Pressure Gauge (also known as the welding gauge) is built for equipment and plants for welding, cutting and allied processes. The WIKA 111.31 pressure gauge is a safety pressure gauge with a solid baffle wall.

The WIKA CPC2000 portable low pressure controller is used in the areas of heating, ventilation, air conditioning, filtration, clean room, and medical technology as a calibrator or as highly-accurate measurement equipment and/or precise pressure transducer. The WIKA CPC2000 low-pressure controller is a mains or battery-operated pressure controller with internal, automatic pressure generation and pressure reference. The pressure generation is achieved using an integrated, electric pump, which makes a positive and/or negative pressure available on both the tube connections. As soon as the instrument is switched on, a zero-point adjustment is automatically carried out, so that a zero-point drift is eliminated. The subsequent preparation of a calibration requires only a few settings. First, using the MENU button, select one of the stored pressure units and the variable pressure change step in the range of 0 … 50 %. Then, once the full scale has been entered in Control Mode, the pressure can be easily increased or decreased by the defined level using the navigation buttons. To check whether the calibration assembly or the test item has a leak, the LEAK button can be used. With this, the pressure is locked into the test assembly and any pressure drop there might be, as well as the the time this takes, is measured and displayed. The CPC2000 has an RS-232 and USB interface, enabling communication and data exchange with a PC. WIKA-Cal calibration software is available for the CPC2000. WIKA-Cal also offers, over and above PC-supported calibration, the management of the calibration and instrument data in an SQL database. The accuracy of the instrument is certified by a factory calibration certificate.
