Equipment designed for EXplosive ATmospheres (ATEX) The tables below enable you to ascertain the product certification according to the protection index (IP66 except for FML, FMS, FMT which are IP56 unless specially requested otherwise) and the required installation area. INTRINSIC SAFETY Principle: gold-plated contact for low current to be associated with an I.S. interface (see fc-rdn-fren) Housing: standard

Electrical or pneumatic functions Electrical contact The electrical contacts used by Georgin are SPDT type. At rest, contact is established between C-NC. NO C Position above the threshold NC Position below the threshold According to the type of action (opening or closure of the electrical circuit), the electrical connection is made on the terminal block between C-NC or C-NO. Electrical functions Fixed dead band (1) Standard Adjustable dead band (2) Tight dead band Nitrogen sealed Expl. pr. (tight dead band) Nitrogen sealed Expl. pr. (tight dead band) 2 SPDT (3) (acting together) Adjustable lagging...

Electrical or pneumatic functions Maximum breaking capacity (resistive load) Contact No. Cable inlets The instruments (with the exception of polyester, stainless steel housings & explosion-proof housing) have one M16 type cable inlet and are supplied with 1 or 2 cable glands 5 to 10 mm in diameter (standard and I.S. instrument). The instrument can also be supplied without cable inlets. Explosion-proof housings are supplied as standard with a 3/4’’NPT type cable inlet. Cable glands are available as an option. The choice of cable gland directly affects the certification, and could lead to the equipment...

Specific features Range and qualification of metal parts in contact with fluid The range information is detailed in the next 3 pages. Standard housing The information "X" denotes, according to the type of instrument, that the connector, bellows, Bourdon tube and the flange of the diaphragm-actuated instrument or the the thermostatic element are made of stainless steel. Explosion-proof housing In addition to the reference, we request you to specify for a pressure switch: - The type of connector (1/2’’GM, ¼’’NPTF, mounting on separator, etc.) - The diaphragm material if applicable (NBR, FKM or...
