pressure gauges with electric contacts PBX100XA + KX.X [Built-In Type]

Transcription

1 PBX00XA + KX.X [BuiltIn Type] They are used to control the electrical operation of compressors, pumps, presses, hydraulic and pneumatics equipment, chemical and petrochemical plant. The contacts open or close the circuit depending on the position of the indicating pointer and they are adjustable over the whole range. For application on severe working conditions, such as rapid and frequent pressure change, vibration and pulsation, they are manufactured with the case liquid filled. The filling drastically reduces the effect of such factors as well as those caused by a corrosive atmosphere, giving longer life and better performances of the pressure gauge and their electric contacts. They are also available with inductive contacts intrinsecally safe. Functional and constructive characteristics. 0.M. brass version Accuracy: ±,6% as per UNI 89 DIN 6085 (). Ambient temperature: C.

() The addition of mechanical electric contacts affects the accuracy of instruments such that % becomes,5%,,6% becomes,4% etc. (add the 50% of accuracy; if the contact is of the magnetically assisted type, this value can't be added within the ±5% of setting point).

3 manometri con contatti elettrici CONTATTI ELETTRICI IN ARIA PBX00 + KX.X [BuiltIn Type] Sliding contacts The electrical sliding contacts guarantee an accurate operation within a controlled hysteresis. However they are rather sensitive to vibration, moreover, very slow pressure changes may cause an electric arc which can reduce its working life. Magnetic SnapAction Contacts This type of contact is universally used to guarantee the reliable operation of gauges under severe vibration. The magnetic action is guaranteed by a "click operation", which improves contact capacity, life and is less sensitive to vibration. The required power to overcome the magnetic resistance causes an hysteresis at setpoint between % to 5% of full scale value. Functional and constructive characteristics Setpoint accuracy: 50% of instrument accuracy. Setpoint hysteresys: 0,% of full scale value. Break rating: 0W/8VA. Maximum rating: 50Vac/0,7A (ohmic load). Contact material: SilverNickel 80/0%. Contact setting: over an arc of 70, by a fixed key fitted to the front lens or by a removable key. Electrical wiring: junction box as per VDE, see table at page 4. Functional and constructive characteristics Setpoint accuracy: 50% of instrument accuracy. Setpoint hysteresys:...5% of full scale value. Break rating: 0W/50VA (0W/0VA for filled version). Maximum rating: 50Vac/A (ohmic load). Contact material: SilverNickel 80/0%.

5 INDUCTIVE SYSTEM PBX00 + K.X [BuiltIn Type] InductiveK Inductive contacts are intrinsically safe and certified to EN 5004/5000 norm with protection degree EEX ia IIC T6. To guarantee such protection degree the contacts must be supplied via a control relay which has the same type of certificate (see our catalogue sheet 08.W0W0). When mounted on instruments with liquid filled case (models 0.M., 0.M.) they are particularly suitable for application on chemical and petrochemical plants with vibrations and frequent operation. The inductive system consist of an inductive sensors that operates without mechanical contact and an external control unit. The control head of inductive sensor contains a transistorized oscillator and two axial coils. The magnetic coupling between the two axial coil is changed by a control flag which is moved by the pointer. This action changes the internal control unit current which is used actual to trigger a switch amplifier which makes the real switching. For further informations see our datasheet 08.W0W0.
