General technical explanations Thread User information Our pressure monitoring products may only be installed and started up by authorised specialists. The safety regulations of country-specific authorities must be observed, especially when working with mains voltages and oxygen, and in potentially explosive areas. Product information The technical information in this catalogue is based upon fundamental testing during product development and empirical values. The information cannot be used for all application scenarios. Testing of the suitability of our products for a specific application (such...

Vacuum The values given in the technical details for the vacuum range are specified in millibars (mbar) below atmospheric pressure. Pressure change rate (~rise / ~fall) The pressure change rate denotes the pressure over time for the rising/falling pressure. The pressure change rate is specified in bar/s or bar/ms. The maximum pressure change rate for SUCO mechanical pressure switches is 1 bar/ms (1,000 bar/s). For SUCO electronic pressure monitoring products the maximum pressure change rate can be up to 5 bar/ms (5,000 bar/s). Over pressure protection The specified over pressure protection in...

Technical explanations for mechanical pressure switches Diaphragm pressure switch NO Piston pressure switch NC 2b Change over What is a mechanical pressure switch? Mechanical pressure switches from SUCO monitor the pressure of liquid or gaseous media, and close or open an electrical circuit on reaching a set threshold. Diaphragm pressure switches SUCO diaphragm pressure switches are used in pressure ranges from 0.1 bar to 100 bar, meaning over pressure safety of 35, 100, 300 and 600 bar, depending on the used diaphragm type. Piston pressure switches Pressure ranges from 10 bar to 400 bar can...

Classification of electrical switch functions Symbol IEC 60617 for RT and condition as new can be assumed as a typical magnitude for the tolerance over the entire temperature range. SPST single pole, single throw SPST single pole, single throw Changeover contacts CO, change over (snap action) SPDT Single pole, double throw B10d value The B10d value specifies the anticipated service life (with a 10% probability of failure). The B10d value is therefore directly dependent on the respective application of the pressure switch. For ohmic loads and currents < 1 A, we specify the B10d value as 1 million cycles...
