Operation and use
The series 0184/0185 switch opens or closes an electrical circuit when a certain
(adjustable) pressure is reached. A diaphragm or piston is moved by the increase
in pressure. The amount of diaphragm deflection or piston travel depends on
the force of the pressure applied and the (adjustable) spring tension. At a prede-
termined deflection of the diaphragm or movement of the piston, a microswitch
is actuated which opens or closes the electrical contacts (changeover).
The pressure switch monitors a preset pressure.
Conditions governing the use of the product
The following general instructions are to be observed at all times to ensure the
correct, safe use of the pressure switch:
•
Observe without fail the warning notices and other instructions laid
down in the operating instructions.
• Observe the applicable safety regulations laid down by the regulatory
bodies in the country of use.
•
Use the switch only for monitoring fluid and gaseous medias.
• Do not exceed the specified limits for e.g. pressures, forces, moments or
temperatures under any circumstances.
•
Give due consideration to the prevailing ambient conditions
(temperature, atmospheric humidity, atmospheric pressure, etc.).
•
Never expose the pressure switch to severe side impacts or vibrations.
• Use the product only in its original condition. Do not carry out any
unauthorized modifications.
•
Remove all items providing protection in transit such as foils,
caps or cartons.
• Disposal of the above-named materials in recycling containers is
permitted.
Operating conditions
Media temperatures other than room temperature (20 °C):
•
The effects of extreme temperatures (relative to room temperature) can
lead to pronounced variations in the switching point or the failure of the
pressure switch.
Type of protection IP65:
Type testing does not apply to all ambient conditions without limitations.
The user is responsible for verifying that the plug-and-socket connection com-
plies with the specified rules and regulations of CE, or whether it may be used
for specialized purposes other than those intended by us.
Use with oxygen:
Diaphragm Pressure Switch:
If oxygen is used, the applicable accident prevention regulations must be
observed. In addition, we recommend a maximum operating pressure of 10
bar, which should not be exceeded.
Piston Pressure Switch:
Piston Pressure Switches are
not
suitable for gaseous media, particulary
oxygen.
Protection against overpressure:
The static overpressure safety is included in the technical data.
The overpressure safety corresponds to the hydraulic, pneumatic part of the
pressure switch. The dynamic rating of the overpressure safety is smaller than
30 to 50%.
