Ettore Cella Pressure Switches

Relative Pressure Switches  

	MINI SERIES PXS PXA PMS     The MINI switches series are ideal for application where space is at a minimum, such as offshore oil rigs and process and energy applications. A welded diaphragm is combined with a snap-action Belleville spring. Enclosure IP66 - all stainless steel AISI 316 Protection mode Ex-ia, Ex-d Contacts SPDT hermetically sealed Repeatability better than 1%
	COMPACT SERIES PCS PCA      The COMPACT series switches are ideal for installation in electrical cabinets as well as on rotating machines, due to its compact and square shape. A diaphragm, combined with an antagonist spring assembly, is used to counteract vibration and offer high reliability. Enclosure IP65 - aluminium or stainless steel Protection mode Ex-ia, Ex-d Contacts SPDT and DPDT Repeatability better than 1%
	MODULAR SERIES MW MA     These switches covers all industrial applications thanks to its wide pressure ranges. A diaphragms is used to provide a perfect measurement value hence guaranteeing HIGH performances. Enclosure IP65 - stainless steel or aluminium (Ex-d) Protection mode Ex-ia, Ex-d Contacts one SPDT - two indipendent SPDT - fixed or adjustable dead-band Repeatability better than 1%
	BOURDON SERIES BWX BAX BA    It is ideal for operation in harsh environments and where the highest level of repeatability is essential. A Bourdon tube is used to convert the pressure value onto electrical action. Enclosure IP65 - stainlees steel or aluminium (Ex-d) Protection mode Ex-ia, Ex-d Contacts one SPDT - two independent SPDT - fixed or adjustable dead-band Repeatability better than 0,5%
