The data can be comfortably evalua- ted with the CS Soft Basic software. Measured data and service reports
can be issued easily and quickly. The following sensors can be con- nected to the freely configurable sensor input of PI 500:

The new thermal flow direction switch VA 409 with direction indication serves for determination of the flow direction of
compressed air and gases especially in closed circular pipelines.

By means of VA 409 with flow direction indication the flow direction of the compressed air can be determined quickly and safely. Compared with the former mechanical paddle flow switches VA 409 is able to detect even the smallest changes in the flow direction quickly and without any mechanical movement.

The direction information in form of a potential-free contact (normally closed max. 60 VDC, 0.5 A) is transferred to the
consumption sensors VA 400/VA 420 or to a separate building management system (mbs). Two LEDs show the flow direction.

In connection with 2 consumption sensors VA 400/VA 420 incoming and outflowing compressed air in closed circular pipelines
can be measured precisely.

The leak detector LD 400 is a handy device for detecting often hidden perforations in pipes and tubes. It is the further development of the proven LD 300 and impresses through a significantly more sensitive sensor technology to provide improved support during the leak detecting process. Plus, the design has been revised in accordance to modern criteria for ergonomics at the workplace and the LD 400 is much more compact and easier to manage than its predecessor.

Leaking gas causes ultrasonic noise. However, a leak must have the size of approximately 1 mm and the pressure must have reached approximately 7 bar before the frequency emits a sound that is audible to the human ear. The leak detector LD 400 can locate leaks in the ultrasonic range, even from a distance of several meters. The LD 400 translates the ultrasonic sound into an audible frequency and makes it easier to detect even the finest holes in the pipes. Sound-proof headphones ensure that the technician can hear the acoustic signal even in the noisy environment of an industrial plant.

Additionally, in extremely loud rooms, we recommend the use of a shotgun microphone with a directional tip. It functions like a directional microphone, prevents annoying background noises and also facilitates the precise localization of leaks in inaccessible areas.
Additionally, an ultrasonic transmitter whose signal penetrates through the smallest openings can be used to detect leaks in pressureless systems.

The PM532 is a mobile power and energy measurement device for large consumers such as air compressors. All components are housed in a rugged, splash-proof plastic case. The PM532 measures currents and voltages of the connected consumer and calculates the performance as well as the energy consumption. The measuring case can be easily connected to the 32A supply line of consumers. For a 16A supply, optional adapters are available that allow you to connect to the built-in 32A CEE socket outlets.

The unit is designed for measurements in the 3-phase power range with up to 32A, wherein the current path will not be additionally secured with a fuse through the measuring kit. It is assumed that the existing installation has a corresponding fuse protection.

The PM532 has three 230V power outlets that are each assigned to one of the three phases. Thus it is possible to also determine the power consumption of external consumers.

The measured values can be read directly from the display. In addition, the most important measurement values can also be queried through the internal RS-485 interface via the Modbus protocol.
