The WIKA 312.20 mechanical test gauge has been specifically designed for the measurement of pressures with high accuracy. With its accuracy class of 0.6, the Bourdon tube pressure gauge is suitable for testing industrial type pressure gauges or for precision measurement in laboratories. For the respective measuring requirement, a scale range between 0 … 0.6 and 0 … 600 bar can be selected. The WIKA 312.20 mechanical test gauge is constructed with a case from stainless steel and wetted parts from copper alloy. The instrument meets the requirements of the international industry standard EN 837-1 for Bourdon tube pressure gauges. The optimal readability of the instrument, with a nominal size of 160 mm, is achieved via a knife-edge pointer and a dial with fine divisions. Supported through the optional mirror band scale, the parallax error can be eliminated.

The SIEMENS SITRANS FUS SONO 3100/SITRANS FUS060 flowmeter consists of a SITRANS FUS SONO 3100 sensor with O-ring or flange transducers depending on the application. The standard version is delivered as a 2-track sensor with or without flanges; 4 tracks are available upon request. Available pipe materials include carbon or stainless steel on request. The SITRANS FUS060 transmitter is engineered for high-performance applications and designed for remote installation in hazardous and non-hazardous environments. In addition to the standard outputs, it also offers communication.

Wherever the process pressure has to be indicated locally and, at the same time, circuits need to be switched, the WIKA PGS21.100 and PGS21.160 switchGAUGE finds its use. Switch contacts (electrical alarm contacts) make or break an electric control circuit dependent upon the position of the instrument pointer. The switch contacts are adjustable over the full extent of the scale range (see DIN 16085), and are mounted predominantly below the dial, though also partly on top of the dial. The instrument pointer (actual value pointer) moves freely across the entire scale range, independent of the setting. The set pointer can be adjusted using a removable adjustment key in the window. Switch contacts consisting of several contacts can also be set to a single set point. Contact actuation is made when the actual value pointer travels beyond or below the desired set point. The pressure gauge is manufactured in accordance with DIN 16085 and fulfils all requirements of the relevant standards (EN 837-1) and regulations for the on-site display of the working pressure of pressure vessels. As switch contacts, magnetic snap-action contacts, reed switches, inductive contacts and electronic contacts are available. Inductive contacts can be used in hazardous areas. For triggering programmable logic controllers (PLC), electronic contacts and reed switches can be used.
