LEAR Siegler has extended its standard range of flow set high volume samplers with the introduction of the PK2100 programmable controller incorporating the air sampling control system (ASCS) software specifically designed for the Lear Siegler flow set high volume air sampler.
The PK2100 controller is a general-purpose single board computer housed in an industrial enclosure with liquid crystal display (LCD) and 12-key keypad.
The controller is configured with an assortment of inputs and outputs both analogue and digital for monitoring and control of the ASCS.
The PK2100 LCD and keypad provide an easy to use method to view and change system parameters, change operating modes, and calibrate the unit.
System real-time inputs connect directly to the PK2100 via screw terminals. Inputs such as wind speed, wind direction, mass flow, temperature, and air pressure, can be monitored.
Four types of control are selectable via the keypad.
Manual control provides a facility to operate the fan constantly. Time control allows the operator to specify specific times and duration of operation. Vector control monitors wind speed and wind direction to operate the fan.
Standby mode allows the change of parameters with the fan off.
Many system variables may be logged using the data logging facility of the ASCS. All values with system date and time are stored for later retrieval via the RS232 port.
