The Cleveland Controls AFS-952 Differential Pressure Sensing Switch is designed to provide precise operation and convenient features for industrial and commercial air handling applications. The AFS-952 can monitor positive, negative, or differential pressure (flow) of air and noncombustible gases. It is commonly used to monitor combustion air, furnace pressure, ventilating blower operation, inflatable structure pressure, fume hood operation, bag house air flow, dirt accumulation in air filters, and heat-transfer air flow. The AFS-952 has a field-adjustable set point range of 0.05"wc to 12.0"wc with an 8-second (± 3 seconds) time delay relay sequence. The time delay prevents nuisance shutdowns due to normal draft fluctuations.
