The GEMÜ 3140 pressure transducer/switch is ideal for pre-
cise measurements in a wide pressure range. The sensor is
suitable for use with both highly viscous and contaminated
media and is also suitable for corrosive media due to its high-
quality material selection. A variety of electrical and mechan-
ical connections are available, depending on the version. The
LED display version boasts a rotatable 4-digit display.
3.3 Function
The GEMÜ 3140 pressure transducer converts the physical
variable pressure into an electrical signal.

terial according to relevant local or national disposal regu-
lations / environmental protection laws.
8.3 Storage

9 Installation in piping
9.1 Installation and safety information
DANGER
Risk of lightning strike!
▶If there is an elevated risk of the device
being damaged by lightning or over-
voltage, an effective lightning protec-
tion system must additionally be put in
place.
DANGER
Use of the product as a stepladder
▶The housings are not designed to be used as a stepladder
for climbing in the plant. They can be damaged if used in
this way and their function impaired. If the housing is
damaged, water, dirt and combustible material can accu-
mulate in the housing interior. This can cause a short-cir-
cuit. Furthermore, the deposits can cause the device to
overheat and may result in an explosion.
NOTICE
▶Handle the unprotected diaphragm with extreme care, as
it is very easily damaged.
NOTICE
▶For use in steam pipes, provide a cooling zone.
NOTICE
▶During installation, avoid high mechanical stresses on the
pressure connection. This can result in the characteristic
shifting or in damage, particularly for very narrow pres-
sure ranges and for devices with a plastic pressure con-
nection.
NOTICE
▶With hydraulic systems, orientate the device such that the
pressure connection is facing upwards. (Vent hole)
NOTICE
▶If the device is to be installed with the pressure connec-
tion at the top, make sure that no liquid flows away along
the housing as this could result in moisture and dirt
blocking the gauge reference in the housing and, in turn,
to the equipment malfunctioning. Where necessary, re-
move dust and dirt from the edge of the electrical con-
nection's union.
NOTICE
▶Make sure that you do not remove the packaging and pro-
tection caps from the device until you are just about to in-
stall it, so that you do not damage the diaphragm or the
threads.
▶Keep the protection caps. Dispose of packaging properly.
