CRYOGENIC TANKS Measuring instruments in cryogenic tanks, ISO containers and tank trailers are used to monitor the level of cryogenic gases. Pressure indicating instruments normally show the absolute pressure or differential pressure. Measuring instruments in tank trailers, in addition, show the pressure before and after the cryogenic pump. On request from OEM manufactures and gas companies, tanks and trailers are equipped with integrated or stand-alone transmitters. Our customers in this field are manufacturers of cryogenic vessels, companies maintaining and refurbishing cryogenic vessels, industrial...

WELDING AND OTHER INDUSTRIAL EQUIPMENT Pressure measuring instruments with a Bourdon tube are frequently used in welding regulators. Such measuring instruments are used in conventional regulators in the traditional “mickey mouse” design as well as in regulators with flow meters, and also as an integrated component in the plastic case of a regulator unit. One measuring instrument shows the pressure in the gas cylinders and the other one the regulated pressure in the gas distribution line. With the exception of traditional welding applications with brass regulators, such measuring instruments on...

VALVES WITH INTEGRATED PRESSURE REGULATORS (VIPR) WIKA cooperates with several renowned valve and regulator manufacturers. As time has passed, the design of regulators has become ever more complex in order to ensure higher protection and better utilisation of the measuring instruments. This has led to the development of measuring instruments that are directly integrated in the valves (VIPR = valve with integrated pressure regulator). Initially as mechanical, and then later as mechatronic/electronic instruments. The task of measuring instruments in such regulators is to indicate the pressure in...

GAS CABINETS Gas cabinets are used for firefighting. The gas cylinders contain inert, non-reactive and non-toxic gases. The market offers a variety of gas cabinets in different configurations, e.g. 1-, 2- and 3-cylinder designs (or based on company configuration). They can be either new, used or reconditioned. A gas cabinet can have different features depending on the specific gas. These features include a gas sensor, a sprinkler head, an overflow sensor, automatic operation with automatic purging and overpressure sensor. The connection and valve specifications for gas cabinets and distribution...

MEDICAL GASES Whether in the emergency room, the operating room, the intensive care unit, the hospital ward or in ambulance vehicles: Medical gases are widely used in hospitals. There is a variety of medical gases: medical air, carbon dioxide (CO2), helium (He), laughing gas (N2O), nitrogen (N2), nitrogen monoxide (NO), oxygen (O2), xenon. To secure smooth supply and distribution of gases, measuring instruments are installed on gas storage tanks or cylinders, valve manifolds, pressure controllers, closure control cabinets as secondary regulators at gas distribution systems and at user stations....

HYDROGEN Because of its calorific value, hydrogen is often used as fuel. Hydrogen fuel cells generate electricity from oxygen and hydrogen. Fuel cells are used in automobiles, spacecraft, remote weather stations and submarines. Other uses for hydrogen are in the fertiliser and paint industries, in laboratories, in the food industry and the chemical industry. Hydrogen is also used in welding processes. TIG welding and plasma welding are particularly noteworthy here. Hydrogen is required as a reducing agent in chemical industries. Hydrogen has higher requirements for material stability than other...
