Centralized lubrication unit pressure switch - DSA series
Typically, pressure switches can be used for oil, lubricants and fluid grease. However, when grease is used, a specific model of pressure switch is required to prevent hardening near the intake. Models with a piezo-resistive sensor function have more than one signal outputs and the device can be programmed to adjust the switching pressure magnitude. These switches are designed for automatic monitoring and display a signal whenever a specific value has been reached for the pressure. For dual-line lubrication systems with centralization, differential switches are used.
