Pressure switch, low range

Orion pressure switches are now available in pressure ranges from 15 mmWG to 2500 mmWG. These low range pressure switches are reliable, compact and low cost. These pressure switches can be used to sense flow of gases, air and also for liquid level regulation; and for a variety of working media by selecting appropriate wetted parts. The electrical switching element is an SPDT snap action micro switch for reliable changeover. The micro switch is rated at 2 A, 250 V AC. Some of the applications are in preventing burnout of heating elements due to insufficient airflow, to single irregularity in flow of air in natural/forced/induced draft boilers, exhaust fans and ventilating systems, instrument cabinets, air curtains, clean rooms, food processing and grain drying, to signal fan failure in exhaust/blower systems, to monitor airflow in drying ovens and kilns and to regulate liquid level in tanks open to atmosphere. Pressure switches are also offered in various higher ranges from 0.1 bars to 400 bar.
