FST-321-SPST

FST-321-SPST is a FST-320 series thermal dispersion flow switch for use with gases, sense changes in the heat transfer characteristics of the gases. The flow switch incorporates a standard SPST relay switch output for control flexibility. OMEGA® controllers can easily be interfaced to perform a variety of control functions.
