External zero span and calibration controls are electrical output. Available with up to three switch mechanisms for level alarm control and shutdown functions the boiler and water column controls are designed for use in steam boiler applications while the models c24 and c25 are for general use. This is why water column is most often used to measure pressures under 1 psi. When we measure water column with our tools it is calibrated at atmospheric pressure or the gauge scale instead of the absolute scale.
Models c24 c25 boiler and water column liquid level switches are single or multi switch units that offer versatility and reliable operation in a variety of applications. Series at11910 series 1910 in flame proof enclosure. Wet wet differential pressure switch for use with most gases and water based solutions. Models c24 c25 boiler and water column liquid level switches.
These low pressures are most often read using a manometer or a magnahelic gauge. Lochinvar 100294587 pressure switch 50 water column pressure switch 50 water column.
