Safety for compressed air supply
If compressed air is not dried before feeding it into the compressed air network, considerable amount of condensate gets accumulated in the air line network and causes malfunctioning of valves, pneumatic components and finally leads to stalling of production activity. Hence, the pressure dew point in compressed air system is a decisive parameter for air quality and should be regularly measure.
In the application of an adsorption dryer, a considerable amount of power must be applied for the drying process. Since the dryer is designed for full load, much energy is wasted if the dryer works on partial load. This can be avoided by a regulation of dew point.
The stationery pressure dew point instrument of AIRSECURE series ECO is a regulator as well as an alarming device. The device has three outputs, out of which the first output triggers the dryer on exceeding the setpoint regulation value of the dryer and initiates a drying cycle.
Another contact is for early warning and the third contact is meant for the signal of main alarm. The alarm is communicated through warning light and by producing acoustic signal at the location.
An additional analog output enables the integration of measured pressure dew point to higher level systems.
Through the integrated RS232-port, connection is possible to a PC based monitoring system. The measurements are represented in a clear graphical form and errors in the plant or at the dryer are immediately detected.
For measurement of pressure dew point, high quality stainless steel sensing elements are used, which are very well proven for many years in the medical pressure dew point measuring systems from the same manufacturer and also guarantees outstanding long term stability.
