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. 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. (1). Single fixed dead band electrical operation: Microswitch "only". Each type of microswitch has its own characteristics, as indicated in the catalogue. Models: 4, 4D, 10, 10D, 16, 16D, 60, 60C, etc. (2). Single adjustable dead band electrical operation: Microswitch combined with a...

: The specific features come after the letter «D». Examples : DFPML, DFPMS and DFPMT for a polyester housing. Function type pages 6 and 7 Georgin has one of the most extensive ranges of electromechanical and electropneumatic security solutions in the world. Because our product range is subject to ongoing development and so as not to impact the safety of your installations, this document enables you to define your overall reference. We will confirm this with our item code. Examples of code numbers Diaphragm-actuated gauge pressure switch (material to be defined) and galvanised steel flange...

RTPF Range and qualification of metal parts in contact with fluid The range information is detailed in the next 3 pages. 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. In addition to the reference, we request you to specify for a pressure switch: - The type of connector (1/2''GM, W'NPTF, mounting on separator, etc.) - The diaphragm material if applicable (NBR, FKM or E.P.) If a treatment such as degreasing, passivation...

Example: For an FD . PX in function 96, the pressure in the HP chamber must be greater than the pressure in the LP chamber by at least: P.HP - P.LP > 0.5 + 0.43 bar P.HP - P.LP > 0.93 bar __

As standard, the dimensions of FB bulbs are 0 14 x 120 mm, and 14 x 40 mm for FBA bulbs ♦ ALLOWABLE CAPILLARY LENGTH (METRES) ♦ Standard capillary length: 2 metres; other lengths on request Standard bulb: 014 x 150mm stainless steel, 010 x 150mm copper (except for ranges around ambient operating temp: 014 x 150mm).

Important remark on probe installation Thermostatic probes must be installed facing down, with the capillary outlet at the top. The measurement probe must not be placed in a horizontal position. The position of the probe can affect the operation of the temperature switch. This type of probe is intended for vertical use, and is placed lower than the housing. Any deviation from these conditions can affect the response time and operation of the device. By design, our temperature switches are filled to allow probe inclination of 45° without affecting operation. Beyond this value, operation is...
