The WIKA DPGS40 differential pressure gauges of the DELTA-line product family are primarily used for the monitoring and control of low differential pressures where there are high requirements regarding one-sided overpressure and static pressure. Typical markets for these products are the shipbuilding industry, process heating technology, the heating, ventilation and air-conditioning industries, the water/wastewater industry, and machine building and plant construction. For these, the primary function of the measuring instruments is the monitoring of filters, compressors and pumps. Wherever a differential pressure must be displayed locally and, at the same time, electrical circuits need to be switched safely dependent on defined differential pressure, the DELTA-comb finds its use. As the pressure passes above or below a defined set point, the switching operation is triggered. The switch point is accessible from the front and can be adjusted in the range of 10 … 100 % of the full-scale value. An assistant scale enables an accurate setting of the switch point and indicates the current set point. Often in these applications, alongside the display of the differential pressure, the current working pressure is also relevant. For this reason, a working pressure indication is integrated within the DELTA-comb differential pressure switch as standard. The two local, easily readable, mechanical displays need no power supply and enable the simultaneous reading of the working and the differential pressure. Furthermore, this saves on an additional measuring and sealing point, reducing additional expense for piping and mounting. The robust aluminium case and shatterproof window enable an extended service life of the product, even under harsh ambient conditions. As a result of the small measuring range of 0 ¦ 250 mbar, the instrument can also be used for applications with low differential pressures.

The WIKA RLS-1000 float switch is a robust, reliable and inexpensive float switch. The monitoring of levels, as well as dry-run protection and overflow protection, are cost-sensitive applications in the machine-building industry, therefore a float switch is a perfect solution for many plants. The RLS-1000 float switch offers reliable measurements for the level in vessels with water, oil, diesel or other liquids by means of a permanent magnet and frictionless reed contacts at max. 4 defined switch points and can be used in a medium temperature range from -30 to +150 °C (-22 to +302 °F). The WIKA RLS-1000 float switch is simple, easy to use and fast to integrate because it does not need to be calibrated or set during the installation. This greatly improves the ease of handling, especially in confined installation situations. Also, since its robust design makes it resistant to vibrations and shocks, maintenance costs are minimal.

The WIKA RLS-2000 float switch is a reliable and inexpensive float switch made of high-quality plastic. The WIKA RLS-2000 float switch is particularly suited for measuring the levels of aggressive and corrosive media, such as bases and acids. For cost-sensitive applications such as the monitoring of levels or overflow and dry-run protection, float switches are an ideal solution. The WIKA RLS-2000 float switch detects the level using a permanent magnet and frictionless reed contacts at up to 4 defined switch points, without contact and thus free from wear. Integration as a limit level switch is simple, convenient and fast, because no adaptation or calibration is required during installation. The robust design minimises service and maintenance costs.
