| GE's BreakMasterTM metal enclosed load interrupter switches provide dependable, economical load switching and protection for medium voltage circuit applications from 2.4kV through 15kV in 600 or 1200 ampere load interrupting ratings. Used mainly as a primary or secondary disconnect switch for transformers, the variety of configurations in which BreakMaster is available also make it useful for specific distribution needs. It can be inserted as a main or feeder switch in PowerVac switchgear or LimitAmp frequency drive lineups. Fault current protection is available using a complete line of current limiting or expulsion fuses. |

The Scimitar range has been built to meet stringent requirements and is corrosion resistant for durable outdoor and indoor use.
The switches are contained within a common stainless steel SF6 filled professional tank with the fuses mounted in air above the gas chamber. Each industrial fuse is sealed against external influences and locked into its own chamber upon insertion. The units can be extensible for direct connection to form multiple plan switchboards without the need to access the gas chambers or for extra cabling.
Features
Ratings up to 15.5kV
Common switching chamber with sealed SF6 environment
Low gas operating pressure
Fully extensible
Indoor and outdoor
Freestanding, transformer mounted or transformer connected |

This device professional monitors the operation process for potentially hazardous conditions and activate an alarm when it is occurred misalignment, the SRT series suppliers of conveyor belt misalignment switch protects the manufacturers of conveyor belt from damage due to belt misalignment or run offB
For normal condition, the belt misalignment switches are generally mounted on both sides and the edge of the conveyor beltB
A small clearance between the contact industrial rollers and a little swaying for the belt edges are allowable.
When the swaying exceeds the normal limit (on/ about 20 mm), the belt edge pushes the contact roller, which drives the switch and operates the contacts, the misalignment switch will reset automatically when the belt resumes normal running.
These control devices are used in pair on each side of conveyor belt detected place, each unit can be equipped with two micro-switches to produce signals indicating the belt misalignment at two deviation pointsB
The first signal point could indicate small belt deviation by sounding an alarm, the second signal point could guard against extreme belt run off by shutting down the conveyorB
The roller is adjustable up to 20‹ in both directions and is positioned approximately 20mm from the conveyor belt , the switch actuation points are adjustable from 0‹ to 35‹ by a simple change of the actuating camsB

CBS
The CBS is a mechanical switch which detects and prevents professional belt misalignment on conveyors suppliers. It reacts to the tilt caused by the misaligned belt. The CBS comes with 2 outputs - 15° and 30° - which trigger a first step alarm and a stop. The sensors are connected to a central monitoring unit, CB2V0A, which can control four sensors and triggers an alarm or stop signal and also provides a time delay.
The cylinders in contact with the belt are available in different options:
Mounted on a stainless steel bearing specifications
-- stainless steel 304 or nylon professional cylinder
Mounted on shaft
-- nylon cylinder
The adjustable support is in stainless steel and allows a simple installation and adjustment of the sensors.
The advantage of this system lies in the fact that the force of contact between the cylinder and the belt is limited to the weight of the cylinder itself. This means that the cylinder is not damaged / cut by the belt even if they are in contact for a certain length of time.
The sensors are usually installed in pairs on each side of the machine.

"The surveillance of the working pressure in a system is a very important operation parameter in fluid power and lubrication systems.
Depending on the type or mode of the control system, the display and / or the indication of relevant pressure levels, different pressure limits or continuous readings are required. In many cases a variety of different sample points are controlled and displayed by pressure gages with professional digital displays at a centre point. Traditionally, these pressure switches are all hydraulically piped up to the sample points.
The Pressotronic now offers a more contemporary and simple method for reliable surveillance of system pressure.
Depending on the application we offer a choice of adjustable pressure switches with digital display directly installed at the sample point or versions with separate sample point professional transmitters and professional remote control and display units. In this case, the transmitter and the professional displays are connected just by simple elastic cables instead of inflexible industrial pipes.
Both versions provide almost fully identical modules. The control and display unit features a three digit Light emitting diode display with good readability even under poor visibility conditions. As a combined unit, the display can be positioned within an angle of 270° .
The control unit itself is designed for 35 mm rail mount. This allows to compile several units without additional installation materiel in professional cabinets.
The transmitter is available for stand alone with an analogue 4-20 mA output. |

The VEGABAR 50 is the new generation of pressure pick-ups VEGA. Thanks to technologies with layer DMS mines and ceramics-capacitive CERTEC, they covers the measurement brackets from -1 to 600 bar in pressure relative and from 0 to 25 bar in absolute pressure with a class of precision which can go until < 0,1%.
According to the criteria of your application, you have the choice between several references offering necessary qualities and performances to you: intrinsic safety, very high behavior with the overloads, membrane levelling, great measurement bracket or excellent behavior with abrasion.
Another outstanding innovation is incorporation directly in the sensor of a datalogger making it possible to record a history of measurement over one definite period.
This new family of sensor is of course integrated in the new concept plics® of VEGA. That means in particular various options of case (plastic, aluminum or stainless) and of the electronic alternatives analogical 4... 20mA/HART® or numerical (Fieldbus Foundation and Profibus Pa). These sensors lay out of approval ATEX for explosive atmospheres gas and dust.
The startup is simpler to realize, either using the module of programming and skewerable indication PLICSCOM with clear texts, or by PC using PACTware according to concept DTM/FDT.
