SUCO’s new developments for the Pressure Monitoring
SUCO Robert Scheuffele GmbH & Co. KG, one of the world’s leading specialists in pressure
monitoring, has introduced two completely new product series at the Hanover Fair in April 2015.
SUCO manufactures robust mechanical pressure switches which can be adjusted in a pressure range
from 0.1 to 400 bar and reach an overpressure safety up to 600 bar. Several thousand variants of thisdiaphragm or piston pressure switches are being operated in different applications for almost all
gaseous and liquid media.
The new so-called “PLUS”-Series represent mechanical pressure switches size hex 24 with intelligent
supplementary functions.
SUCO offers the versions NC (normally closed) or NO (normally open) with integrated connectors like
DEUTSCH 2P or 3P, AMP Superseal, Packard MetriPack 280, AMP Junior Timer, M12 x 1 andothers. The electric contact will be easily be reached by just putting together the integrated
connectors with the counter plug. Don’t be worried any longer about inconvenient cable or connection
troubles! Thereby these product series are designed according to the protection degrees IP67 (orIP6K9K) depending on the manufacturer. These approved standard pressure switches have beenfurther developed and include now additionally security functions.
Moreover SUCO offers the versions which include diagnostic functions (fail-safe) with short-circuitand cable break detection according to NAMUR. Such versions are of a special interest for safetysystems as for example brake systems, hydrostatics steering systems or fire-fighting systems. The“PLUS”-Series pressure switches are also available in a version with varistor that allows limiting theflyback voltage efficiently. Thereby the generated overvoltage protection extends the contact lifecycle.
Furthermore, an active reduction of EMI emissions will be reached by switching of the pressureswitches.
Temperature-controlled switching, which can be interesting for the filter monitoring, will be the next
development step. Due to this function it is easy to avoid the incorrect switch status at low
temperatures and hence high viscosity of the medium.
In the future SUCO also can offer a current limitation as for the engine’s “soft start” or for extreme

Furthermore SUCO offers the display of the switchingstatus due to integrated LED. This may be of a particular interest if control units are installed far awayfrom the machines or systems. Some of those security functions can be combined within one
pressure switch.
Due to the above called new developments the customer receives numerous additional security
functions integrated in millionfold proven pressure switches for an attractive price.
Beside these new mechanical switches SUCO has also presented at the Hanover Fair a complete
new product line of electronic pressure switches and pressure transmitters - called „Performance“.
These pressure monitoring elements are based on ceramic sensors in thick film technology. The
entire electronics fits into the standard housings of the mechanical pressure switches hex 24 withintegrated connector. This enables the automation of the production process and – as a result – anattractive price.
The electronic pressure switches offer this robust technology in the range of 0 to 100 bar. Thehousings are made of stainless steel and are available with such integrated connectors as
DEUTSCH, AMP Superseal, MP 12x1, DIN and wired. The electronic pressure switches are adjusted
at factory at a desired switching point. The second version enables the user to adjust the set point byhimself by just turning the switching point with the adjusting screw. These electronic switches areavailable as normally open (NO) or normally closed (NC) versions with the switching output. SUCO
will present these products at an excellent price-performance ratio.
The “Performance” transmitters are also available for the pressure range from 0 to 100 bar and areprovided with output signal 0 - 10 V or 4 - 20 mA. The technical versions include the above called
integrated connectors, the stainless steel housing and the common thread G 1/4 E or NPT ¼. As astandard seal a PU material is provided here, which is particularly well suited for a variety of media.
On request, the "Performance" products can also be delivered with the known sealing materials NBR,EPDM or FKM.
