DESCRIPTION:
This end of line pressure switch guarantees the correct operating pressure and the line inversion in dual line
installations.
When lubricant pressure in the line reaches the pre-set value, the pressure switch controls, through the electric
or electronic equipment, the lighting of a lamp and, if the installation is equipped with an electric controlled
line pressure inverter, it drives the line inversion.
The end of line pressure switch comprises of:
1 sturdy block with 2 ¼” BSP inlet ports.
2 micro-switches.
Pressure switch Part No. 1124456;
Same as Part No. 1124415 but with explosion proof switch.
2 pressure adjustment valves.
2 pressure gauges 2 air bleed valves.
Types of Pressure Switch:
Pressure switch Part No. 1124440;
Fitted at the end of the main line, checks the correct operating pressure and, for installation with hydraulic
inverter, controls the inversion from Line 1 to Line 2 and vice-versa.
Pressostato No. 1124402:
Same as Part No. 1124440 but with explosion proof switch.
Pressure switch Part No. 1124447;
Particularly suitable for installations with many lubricant feeders and with many secondary lines.
This switch must be fitted at the end of the main line or at the end of a particularly important secondary line
And is electrically connected to another pressure switch mounted on the other end of the line. If one of the two
pressure switches is not activated by lubricant pressure, the electric equipment signals an alarm to stop the
machine. Only if both pressure switches are acted upon by the correct lubricant pressure, the electric
equipment signals the line inversion.
Pressure switch Part No. 1124415;
Same as Part No. 1124440 but mounted in a waterproof box. Protection degree IP 55.
