Profile: POLAR CONTROLS, INC deals with thermal and airflow system controllers, monitor circuits, smoke detectors & alarm systems. Our products include PCI-1007 airflow/temperature sensor, PCI-1008 micro airflow/temperature sensor, PCI-1022 dual temperature sensor, PCI-1053 intelligent phase angle control module, PCI-1055 real time multi-sense instrument, customized fan controllers and low pressure differential pressure switch. Our PCI-1008 micro air flow/temperature sensor is a solid state air flow sensor/switch designed for use with the MSI-20 (smart sensor hub) or as a standalone device in embedded applications. PCI-1008 design allows for many years of operation without the need for re-calibration. The separate channel for airflow and temperature minimizes the effect of self heating. The sensor head measures 0.250" x 0.325" x 0.700". The sensor head is attached to the sensor body, which measures 0.250" x 0.325" x 5". This tiny sensor minimizes the effect on the air flow and allows a user to place several sensors within the same air flow.
