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 CPC4000 industrial pressure controller offers a broad pressure range from -1 ¦ 210 bar. This instrument is available as a desktop or as a 19″ rack-mounting kit. It can have up to two reference pressure sensors and an optional barometer for displaying barometric pressure or be used to emulate gauge or absolute pressure. Since the CPC4000 offers an accuracy of up to 0.02 % IS-50, and controls pressure with a high stability, it is particularly suited as a production tool for transmitter manufacturing, a calibration and maintenance tool for pressure measuring instruments or as a factory/working standard for the calibration of all types of pressure measuring instruments. The leak test and burst test special applications allow CPC4000 to be used as a pressure line testing equipment. The optional automatic contamination prevention system make the CPC4000 an ideal solution in oil and gas plants. Maximum ease-of-use is achieved through the touchscreen and the simple and intuitive menu navigation. In addition, the large number of menu languages add to its operability. The instrument can have up to two internal pressure sensors and the ranges for each reference pressure sensor are determined by the customer within the allowable range. Depending on the application, the operator can choose between three set-point entry methods: Direct entry of the pressure value (set point) which will be controlled via touchscreen keypad. Define steps to reach the desired pressure value by either defining fixed pressure increments or a percentage of span value. User-defined programmable test sequences.

Stainless steel pressure sensors with measuring ranges up to 1,000 bar are available for the WIKA CPH6300 Pressure Indicator. The robust and waterproof design makes the CPH6300 ideal for use in adverse environments. The digital indicator automatically detects the measuring range of the connected pressure sensor and guarantees a highly accurate pressure measurement. The WIKA CPH6300 Pressure Indicator can be used for measuring both gauge and absolute pressure. Differential pressure measurement is possible with the 2-channel version CPH6300-S2, and two connected model CPT6200 reference pressure sensors. Selectable pressure units here are bar, mbar, psi, Pa, kPa, MPa, mmHg, inHg, mH2O and one customer-specific unit. An integrated data logger and various other functions such as Min., Max., Hold, Tare, zero point adjustment, alarm, power-off, peak value detection (1,000 measurements/s), average value filter, etc. ensure that the CPH6300 can be used for many different applications. The large, backlit display and also a long battery life complete the features of the CPH6300 Pressure Indicator. In addition to the GSoft data logger evaluation software for the tabular and graphical representation of the logged data, WIKA-Cal calibration software for calibration tasks is also available. WIKA-Cal also offers, over and above PC-supported calibration, the management of the calibration and instrument data in an SQL database. A USB interface is available for the data transfer.

The intrinsically safe Danfoss MBS 4201, MBS 4251, MBS 4701 and MBS 4751 pressure transmitter program is designed for use in hazardous environments. It offers a reliable pressure measurement, even in harsh applications with severe medium influences like cavitation, liquid hammer or pressure peaks. The Danfoss MBS 4201 and MBS 4251 pressure transmitters are Ex ia IIC T6…T4 explosion protected according to the ATEX directive 94/9/EC. In contrast, the Danfoss MBS 4701 and MBS 4751 pressure transmitters are Ex ia IIC T4 explosion protected. Both series come with 4“20 mA output signal, absolute or gauge (relative) versions, measuring ranges from 0…600 bar, zero point and span adjustment, plug connection and a wide range of pressure connections. Excellent vibration stability, robust construction, and a high degree of EMC/EMI protection equip the pressure transmitter to meet the most stringent industrial requirements.
