Pressure gauges with electric contacts

Instrumentation · Pressure

Nuova Fima MCE18 pressure gauges with electric contacts combine local pressure indication with switching of electrical circuits, in all-stainless-steel construction and 100 mm (4") nominal size. The contacts open or close the circuit depending on the pointer position and are adjustable across the whole scale. They are used to control and protect compressors, pumps, presses and hydraulic, oil-hydraulic and pneumatic circuits, as well as in chemical and petrochemical plants. They cover ranges from 0…1 to 0…1600 bar and vacuum, with ±1.0% accuracy to EN 837-1 and DIN 16085 in the standard version (±1.6% filled), maximum working pressure of 75% of full scale and process fluid temperature up to +100 °C (+65 °C filled). They accept one or two sliding, magnetic snap-action, electronic or inductive contacts, the latter available in an intrinsically safe ATEX version. For demanding conditions with rapid and frequent pressure changes, vibration or pulsation, they are supplied filled with silicone oil (IP65), improving the durability and stability of both gauge and contacts. The connection is G 1/2 A or 1/2-14 NPT in AISI 316L, and they comply with the LVD 2014/35/EU and PED 2014/68/EU Directives. At Tecnovent we help you choose the type and number of contacts for your control logic.
