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...

Adjustment range of switching point The pressure range within which the switching point of an electronic pressure switch can be set is called adjustment range. The switching point corresponds to the pressure value at which the electric circuit of the output is opened or closed. Window function In the window function, the switch signal is programmed such that it remains ON or OFF between two values. This means a defined pressure range can be monitored. This function is only possible on the 053X series. pressure profile Hysteresis Rising/falling switching point The difference between the rising...

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 signicant influence on the accuracy of...

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...

General technical explanations 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 as...

RoHSII compliant Values 30% lower than in the table above must be used for brass housings. Gaseous applications In particular using additional sealant to attain the required leak tightness may be necessary for gas applications. 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...
