Inclined tube manometers are basic, reliable and dependable indicators for positive, negative and differential pressures. There are no moving parts so there is nothing to wear out and they do not suffer the effects of vibration.

A range of gauges for use on air and other non-corrosive gases to quickly indicate positive, negative or differential pressure. Easily applied to systems to monitor fan and blower pressures, filter condition, dust and asbestos extraction plant, clean rooms, inflated buildings amongst many other applications. No maintenance required and no manometer fluid to freeze or evaporate. Minimum range 0-1250Pa.

These differential pressure switches have been designed for use in air handling units. The pressure switches are robust, of proven design and rated at IP 54. Typical uses for differential pressure switches include filter and fan monitoring. For example when the differential pressure across a filter exceeds the set-point, the output relay contact is closed sending an alarm message to, say, a BMS system.
