The HVP-4000AFC-Series
high volume air samplers are housed in a clear-anodized aluminum outdoor
shelter. The units incorporate a maintenance-free,
two or three stage centrifugal blower powered by a brushless, variable
speed, maintenance free motor. Blower selection is dependent upon individual
sampling environment. The speed of the motor is controlled by a programmable
logic controller (PLC) that accepts an input from a mass flow sensor mounted
in the sample air flow stream. The PLC detects changes in the operator’s
pre-set flow rate due to changes in temperature, barometric pressure and
pressure drop due to dust loading on filter media. It compensates for
these changes by adjusting the motor speed to maintain the pre-set flow
rate. The illuminated, graphic LCD displays the operator’s Pre-Set Flow Rate, Instantaneous Flow Rate, Total Volume of Air Sampled, and Elapsed Sample Time. Networking and Communication option set-ups include: two (selectable) RS232/RS485 ports, a 4-20 mA and/or 0-10 VDC analog output proportional to flow, the ability to send & receive SMS messages to/from any CDMA/GSM cellular phone for possibly alerting/reporting any pre-defined event via text message, remote or local data acquisition, data logging in MS Excel format, and a custom remote access utility that allows complete control of the unit from a remote location. |
