Sensor with a loop powered 4-20mA signal to monitor a partial vacuum in an air scrubber system down to minus 10 inH2O compared to atmosphere. This version of the DMP343 low pressure transmitter has a negative pressure range for measuring partial vacuum pressures.
Air scrubbers generate negative air pressure to remove contaminants from a work environment. The negative pressure produced by the air scrubber creates a low pressure zone in the area to be cleaned, resulting in airflow through ducting connected to a higher pressure zone outside the contaminated area.
