Explanation of symbols
WARNING!
... indicates a potentially dangerous situation that can result
in serious injury or death, if not avoided.
Information
… points out useful tips, recommendations and information
for ecient and trouble-free operation.
2. Safety
WARNING!
Before installation, commissioning and operation, ensure
that the appropriate pressure gauge has been selected in
terms of measuring range, design and specic measuring
conditions.
In order to guarantee the measuring accuracy and long-term
stability specied, the corresponding load limits must be
observed.
Only work on the gauge with the voltage disconnected.
Non-observance can result in serious injury and/or damage
to equipment.
Further important safety instructions can be found in the
individual chapters of these operating instructions.
2.1 Intended use
The pressure gauges with switch contacts, switchGAUGE models PGS10,
PGS11 and PGS21, are used for controlling industrial processes for plant
monitoring and for the switching of circuits.

2. Safety
The pressure gauge has been designed and built solely for the intended
use described here, and may only be used accordingly.
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.
2.2 Personnel qualication
WARNING!
Risk of injury should qualication be insucient!
Improper handling can result in considerable injury to
personnel and damage to equipment.
■ The activities described in these operating instructions
may only be carried out by skilled personnel who have the
qualications described below.
Skilled personnel
Skilled personnel are understood to be personnel who, based on their
technical training, knowledge of measurement and control technology and
on their experience and knowledge of country-specic regulations, current
standards and directives, are capable of carrying out the work described
and independently recognising potential hazards.
2.3 Special hazards
WARNING!
Dangerous pressure media such as oxygen, acetylene,
ammable gases or liquids, toxic gases or liquids as well
as for refrigeration plants or compressors require attention
above the standard regulations. Here the specic safety
codes or regulations must be considered.
WARNING!
Residual media in dismounted pressure gauges may result
in a risk to people, the environment and the system.Take
sucient precautionary measures.

4. Design and function / 5. Electrical switch contacts
4. Design and function
Description
Bourdon tube measuring elements are widely used in technical pressure
measurement due to their robustness and ease-of-use. Under the inuence
of pressure, these measuring elements deform within their elastic limits.
This motion is converted, via a mechanical movement (toothed gear), into
a rotational motion.To this, an electrical limit switch is connected - the
magnetic snap-action contact.The contact closes or opens the connected
electrical circuits when the settable limit values are exceeded.
Scope of delivery
Cross-check scope of delivery with delivery note.
5. Electrical switch contacts
Electrical connection
The electrical connection must only be made by qualied skilled
personnel
Connection of the switches via cable or via screw terminals in the
terminal box (L-connector)
The terminal assignment is stated on the product label of the pressure
gauge
The gauges must be connected to the equipotential bonding of the plant
Electromagnetic compatibility
EMC per EN 60947-5-2.
The instruments are to be protected against strong electromagnetic elds.

Magnetic snap-action contact (normally closed or normally open)
The instruments are delivered with a single or double contact (normally
closed or normally open).
With 'normally closed', the contact ag is engaged with the limit switch and,
on rising pressure, disengages from the contact via the actuator attached to
the pointer.The circuit will be interrupted.
With 'normally open' the contact ag follows the pointer until the limit value
is reached. Once the limit value has been exceeded, the contact ag
engages and the circuit is closed.
The switching function of the switch is indicated by the index 1, 2, 12, 11
or 22.
