Pharmaceutical Industry air quality filter monitoring DE27 – Digital Differential Pressure Transmitter

Pharmaceutical industry needs to maintain strict air quality in there plant to ensure quality of the medicinal product. in order to ensure the healthy air quality it is essential to monitor the fresh air in take filters for clogging or filter break through.

FISCHER Germany DE27 is a multi-function differential pressure transmitter with a 2-wire or 3-wire electrical interface brought to you by ALVI Automation- India, Gas Alarm- India in association with ALVI Technologies Austrlalia.
It is suitable for accurate measurement of positive / negative gauge pressure or
differential pressure of air and gases.
