These switches are ideal for use in harsh environments and where the highest level of repeatability is essential.
A Bourdon tube is used to convert the pressure value on electrical action.
The series of pressure switches BWX for high pressure is weather resistant thanks to IP65 with stainless steel housing and ATEX Ex ia Ex-GAS & DUST iaD and has electrical contacts 1 SPDT or 2 SPDT independent.
These switches cover every industrial applications due to their wide ranges of pressure.
A diaphragm is used to provide an ideal value of measurement thus ensuring high performance.
Equipment certified according to:
- PED 97/23 EC Annex I Category IV Modules B + D
- Directive B.T. 73/23 and 93/68 EEC
- ATEX Directive 94/9 EC Group II Cat 1GD Annex III and IV.
Control range: it is the pressure range within which the unit will give a signal (contact changeover)
Differential:it is the difference between the pressure of contact closing and the opening pressure of contact
Allowable pressure: most permanent pressure or instant bearable unit
Test pressure: the greater the pressure at which the drive can be subjected, for example during the verification of system leakage.
This pressure should not be the constant pressure of the system.
Min burst pressure:it is the pressure that the sensitive element can withstand without leakage to occur.
