Industrial Miniature Flow Switch

The Bamford Ajax AJ series of Miniature Flow Indicators are ruggedly constructed to provide automatic control and protection of machinery and plant where it is essential to monitor low flows of cooling water, lubricating oils, etc. All models have high quality gunmetal bodies with internal wetted parts in manganese bronze as standard or other materials as an option. They are fitted with armoured glass windows to give a visual indication of flow. The switchbox houses a standard precision snap action single pole double throw micro switch which can be factory set or field adjustable. Micro switches with silver plated noble metal contacts are also available for use on I.S. circuitry. Both models are similar in action where a flow of liquid displaces a spool or vane which in turn operates a control spindle, through a patented rolling seal, which makes contact with the micro switch. By adjusting the position of the micro switch, an alarm trip can be achieved at differing flow rates.
