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...

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...

Technical explanations for electronic pressure switches What is an electronic pressure switch? An electronic pressure switch converts the medium pressure which is present at the measuring cell into a digital, electrical switch signal (ON/OFF). An electronic pressure switch is more complex than a mechanical pressure switch, and thus generally more expensive. As an electronic pressure switch has no moving parts (relative to each other), it usually has a much prolonged service life and provides a higher level of precision (depending on application). The hysteresis can be set over a wide range...

Switching point accuracy and tolerances The switching point accuracy of electronic pressure switches is specified by SUCO and relates to the full scale value (FS). The switching point tolerances specified by us are valid at room temperature (RT) and new state. The values can change as a result of temperature, ageing and application specific conditions. Switching points can either be set at the factory or by the customer on site (depending on model). Hysteresis Rising/falling switching point The difference between the rising (upper) and falling (lower) switching points (refer to the figure)...

Technical explanations for electronic pressure switches PNP output / high-side / plus-switching PNP output (plus-switching) is the most popular variant in Europe. Here the load is connected to the output of the switch and ground (GND as reference potential). NPN output / low-side / minus-switching For an NPN output (minus-switching), the load is connected to the switching output and to the positive line of the supply voltage (Uv+ as reference potential). Temperature errors and ranges The temperature (both of the medium and environment) generally has a significant influence on the accuracy...

Sampling rate The sampling rate (or sampling frequency) defines the number of samples per time unit (typically in seconds or milliseconds) taken from an analogue signal and converted to a digital signal. The sampling rate is an indicator of how fast the output signal of an electronic pressure switch responds to the pressure change at the input. CE mark Electronic pressure switches from SUCO fall under the 2014/30/EU EMC Directive. EC declarations of conformity have been issued for the electronic pressure switches are available on request or can be downloaded from our website. The relevant...

Technical explanations for electronic pressure switches Conversion chart for pressure units Insulation strength According to the latest specifications for immunity to surges and lightning protection, the following must be taken into account when testing insulation strength: With insulation test devices having an inner resistance exceeding 42 Ohm, the insulation strength of electronic pressure switches can be tested up to 500 VDC. All contacts must be tested short-circuited against the housing. For a specific threshold value of test voltage, the protective circuit for surge protection is...

Order correctly - it's quite simpleExplanation of SUCO order numbers 0170 Diaphragm pressure switches with spade terminal Order number The first four digits indicate the type number: Our example: Diaphragm pressure switch with spade terminals, type 0170 By these three digits, the type of construction and the setting range are determined Our example: overpressure safe up to 100 bar, adjustment range 0.3 - 1.5 bar. These two digits provide information about the desired thread. Our example: NPT 1/8. Important - the code for the seal material: 1 for NBR (Buna-N): hydraulic fluid, machine oil,...
