- class PSE100P
- The vacuum switch with pneumatic output, in series PSE 100 P, allows thevacuum level in the system to be checked by means of a patented system.This vacuum switch is available in two versions: N.O. version recommen-ded for the «air saving» function on a venturi and N.C. version for the «sa-fety»function (part present, etc.) and «grafcet signal».
- class PSE100PK
- The vacuum switch with pneumatic output, in series PSE 100 PK, allows the vacuum level in the system to be checked by means of a patented sys-tem.Thanks to its high precision it is particulary suitable for the control of micro-leaks and the control of vacuum volumes of more than 1 litre. ADVANTAGES: universal solution, high precision, explosion-proof.
- class PSA100C
- The electronic vacuum switch in series PSA100C is the most efficient CO-VAL pressure measuring component. It allows easy installation on all machines and robots, etc., thanks to its compact lightweight design. ADVANTAGES: simplified adjustment and threshold locking, display inversion
- class PSE 100 E
- The vacuum switch with electric output, in series PSE 100 E, allows the vacuum level in the system to be checked by means of a patented system. It can be adapted to all electric automatic controller systems.The choice between the N.O. and N.C. function is made when wiring.
- class PSP 100 C
- The lastest model of COVAL’s electronic vacuum switch family integrates threshold and hysterisis setting in standard. 3 vacuum connections (1/8 G Male, M5 female or Base M5) and 2 electrical connections (2 meters cable and M8 connector) make up the standard range.
- class vacuum gauge VAF
- Vacuum gauges in series VAF 111 are recommended for the creation of avacuum level for maintenance, checking and adjustment.On option, they can be fitted on venturis in series GVP, reference GVOVAF11140.
