Overpressure indicator used to prevent the build-up of excessively high pressure inside silos or tanks. The indicator is sensitive to the pressure exerted on the instrument's diaphragm, which actuates the microswitch located inside. It can be used in the presence of liquids and/or solids, but direct contact should be avoided as this could impair its operation. Sturdy construction with aluminium housing at an excellent price-performance ratio. No power supply required.
