Electrical or pneumatic functions ELECTRICAL CONTACT The electrical contacts used by Georgin are SPDT type. At rest, contact is established between C-NC. Position au-dessus du seuil Position en-dessous du seuil 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, 98, 60, 60C, ... (2). Single adjustable...

Maximum breaking capacity (resistive load) Pneumatic function type The control fluid must be compatible with the ISO-VG 10 standard (air, nitrogen, etc.). Maximum allowable filtration 5 pm. The standard materials for the cell body are polyamide, brass, and/or aluminium. The seals are made of NBR (other types on request). For certain models, exhaust is via open cable gland or screw terminal (mandatory for ATEX models). The control pressure applied to the unit affects the dead band: the lower the supply pressure, the smaller the dead band, and vice-versa. POTENTIOMETRIC FUNCTION...

Instrument type pages 5 to 7 Electrical function type pages 3 and 4 DEAD BAND TABLE READING GUIDE Applicable to tables on pages 10/11/12 Example on P . PX type pressure switch A P . PX denotes a P series gauge pressure switch. For the sensitive element of P . PX with stainless steel bellows, the maximum pressure is 15 bar Its scale is 0.5 to 10 bar, which means that a setpoint can be adjusted when the pressure drops to between 0.5 and 10 bar. Please note that the setting range for a pressure rise setpoint is dependent on the associated microswitch. Note: the adjustment plate is indicative...

PX RTPE Specific feature(s) Range and qualification or parts in contact with the fluid The range information is detailed in the next three pages. The information "X" denotes, according to the type ,of instrument, that the , connector, bellows, Bourdon tube ancrthe flange of the diaphragm-actuated instrument or the the thermostatic element are made ofstainless steel. ddition to the referenc&.you still have to specify for a pressure switch: e type, ofconnector.

▲ Certain models can be produced for P static < 0. Please consult us. ♦ The DMKBV can only be produced with a "Perbunan" diaphragm. Diaphragm instruments MUST be mounted vertically (with adjustment screw facing upwards), with the diaphragm horizontal, on an appropriate mount. • DMPB instruments are not advised for use on water. ♦ DML, DMPB instruments can have a very slight leak in the upper part of the diaphragm every time the state changes. BELLOWS-ACTUATED DIFFERENTIAL PRESSURE SWITCHES Example: For a DPB . QX11 in function 96, the pressure in the HP chamber must be greater than the...

Standard capillary length: 2 metres ▲ Other dimensions can be envisaged if the ambient temperature and the adjusted temperature do not overlap. In WX range, 14.150 mm is the one and only length available

Important remark on probe installation operation of Beyond this 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 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. value, operation is...
