The safety pressure limiter is a safety switching devices for limiting the pressure in
accordance with EN12263.
The
electronic safety pressure DB-1000/2, the combination of a pressure limiter
(PZH) and a safety pressure limiter (PZHH) are located in a common housing and
thereby operate independently.
Pressure
limiter (PZH) and safety pressure limiter (PZHH) monitor their own pressure
threshold. When exceeding the respective output relay is deactivated and a
signal LED flashes.
The release
of the PZH of a pushbutton on the housing. The PZHH can be reset only after
removing the cover by a button. The pressure cells of the PZH and PZHH be
dimensioned depending on the application.

Pressure limiter for subcritical and transcritical applications

• Nominal pressure: allowed to 500bar, pressure thresholds adjusted as needed
• Pressure sensors: stainless steel membrane, overload-proof up to 2 x rated pressure, burst pressure is 2.5 times the nominal pressure
• The safety pressure limiter is suitable for use in conjunction with all refrigerants of the media groups 1 and 2 in accordance with Pressure Equipment Directive 97/23 / EC, for example,

• Mg1: NH3 (R717)
• Mg2: R22, R134a, R507, R23, R744 (CO2), R404a, R407A, R407c

• Refrigeration systems,
• heat pumps,
• Boiler,
• Hot water systems,
• Biogas plants,
• Hydraulic systems

Mechanical pressure switches
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 thousands of variants of these diaphragm or piston pressure switches are being operated in different applications for almost all gaseous and liquid media.
Electronic pressure switches
SUCO’s electronic pressure switches offer high accuracy, adjustable switching points, long-term stability and robust technology in the range of 0-600 bar. Electronic evaluation of switching point permits extremely small or very large hysteresis settings. Additionally, electronic pressure switches can be equipped with supplementary functions, such as optical display or menu control.

SUCO offers various normally-closed and normally-opened solutions with:

• male and female thread
• diaphragm and piston technology
• mechanical contacts and electrical outputs
• different sealing materials for all kind of media and temperature ranges
• integrated connectors Deutsch 2P &. 3P, AMP Superseal, Packard MetriPack 280, AMP Junior Timer and M12x1

Due to their favorable price-performance ratio and a wide range of variants mechanical pressure switches are used in almost all areas of mechanical engineering and construction.
