The factory set pressure switches series 901
The switching pressure can be defined at a value of between 5 mbar and 12 bar in the overpressure range and between -5 mbar and -900 mbar in the vacuum range.
The main area of use for the compact pressure switches series 901 is in monitoring filling levels and filters, as well as in monitoring overpressure, vacuum or differential pressure in closed systems. These pressure switches are suitable for liquid and gaseous media including aggressive media.

Switches, regulators and display devices permit reliable monitoring of the vacuum system. An important aspect is that these devices must be perfectly matched to the system being monitored, but this is no problem with the available spectrum of devices!
- Vacuum switches
- Pressure switches
- Combined vacuum/pressure switches
- Accessories for vacuum switches
- Measuring and control devices
- Safety devices

Electro-Mechanical Vacuum Switches
These switches use a vacuum actuated membrane to operate a mechanical micro switch. All switches can be wired normally closed or normally open. The vacuum level to which the switch operates can be set with the manually adjustable and lockable screw. The VES-02B comes with two fixing holes molded into the housing, whereas the VES-01B comes with fixings in two extended ears.

The efector 500 is based on a ceramic measuring pressure cell which converts the measured quantity of pressure into a capacitive signal as a result of the deflection of a diaphragm. A microprocessor controls the evaluation of the electrical signal. For the efector 500 the system pressure is directly indicated on the unit by an LED display.
The extraordinary mechanical characteristics of the efector 500 result from the following design features:
The measuring pressure cell is designed in such a way that the diaphragm is supported by the base in the case of overload pressure. This leads to a high strength against hidden pressure peaks at values outside the measuring range.
The measuring pressure cell consists of ceramic which has ideal elastic features thus ensuring a high long-term stability of the diaphragm.
The electronic circuitry is made in film technology, i.e. a flexible, temperature-stable and extremely resistant polyimide film is used as a carrier for the SMD components. In conjunction with a special potting compound this leads to a high shock and vibration resistance.

Anyone who uses ultra-low pressure, vacuum and differential switches can tell you that they will inevitably wear down in low pressure environments, causing contact erosion, loose terminals, switch instability and leakage.
The result? Equipment failure, downtime, and productivity setbacks no busy manufacturer can afford. Fortunately, now there's an alternative-
New Solution to Ultra Low Pressure Switch Problems Helps Avoid Leakage, Set Point Instability and Contact Resistance- an innovation in switch design that combines special gold crossbar contacts with a revolutionary "all-in-one-weld" contact/terminal construction for switches that deliver reliability, long life in harsh, low pressure environments—the MAM005 line of ultra-low pressure, vacuum and differential switches.
Most important, not only do these rugged and dependable switches last longer, they're comparatively priced, no matter if you're just looking for pre-configured switches available for immediate shipping, standard switches tailored to your business needs, or custom-designed switches for special applications

Pressure Switches
Better under pressure. For years, manufacturers and operators of heavy-duty equipment have trusted Honeywell pressure and vacuum switches. They're proven under pressure, in applications constantly under attack from chemical splashes, performance spikes and other harsh environments. These switches sense a change in the pressure or vacuum, opening or closing an electrical circuit when the designated point is reached.
Honeywell offers an impressive line:
-Compact size
-Durable construction
-Enhanced set point integrity
-Customisation and modifications available

DRIESCHER - Outdoor Switch-Disconnector
Type FLa 15/97
• Rated voltage 12 kV, 24 kV, 36 kV and 38.5 kV
• Rated current 400 A and 630 A
• 1-pole and 3-pole design
Contrary to former outdoor load-break switches in which it was common practice for the arc to be extinguished in oil, with the new developed outdoor switch-disconnector FLa 15/97 arc extinction takes place in a vacuum interrupter.
Based on a patented insulating system there is also no liquid or gaseous medium required for the external insulation strength of the vacuum interrupters.
The vacuum quenching device is embedded in a weather-proof insulating housing.
This switchgear is therefore also recommended for special applications (e.g. in water protection areas).
The outdoor switch-disconnector is capable of switching on its rated current as well as its rated short-circuit making current via the main contact system.
The disconnecting process is implemented via the shunt-connected vacuum interrupters, resulting in no external arcing phenomena.
A fully developed eccentric make-and-break mechanism operates the vacuum interrupters and ensures Class M2 with regard to the mechanical strength (corresponds to 5000 mechanical operating cycles).Fefer brochure 766e
