Pressure switches switch mechanically or electronically when the pressure of a gas or liquid exceeds or falls below a certain value. The devices in the DSP series are suitable for pressure-dependent switching of motors for pumps. The cut-out pressure and pressure difference are adjustable. The pressure connection, pressure sensor element, switching mechanism and electrical connections are mounted on a high-quality plastic base plate. The cover protects the switch from environmental influences. Properties: - user-friendly assembly and installation, - normally closed contacts for single to three-phase motors, - adjustable cut-out pressure and pressure difference, - compact design, - cable entry equipped with strain relief as standard, - contact protection according to 0106, Part 100 Mounting type: The assembly and fastening takes place via the threaded connection in the immediate vicinity of the pressure vessel. The robust plastic housing corresponds to the protection against splash water from all sides. Areas of application: The pressure switches in the DSP series can be used to monitor and control the pressure of liquids in pipes and boilers and to automatically switch pump motors, e.g. for water supplies.
