Information
Short Description

The VSA 24-DM /-DH Differential Pressure Sensor monitors pressure in hydraulic, lubricant and coolant systems

Details The differential pressure sensor VSA 24-D... is a microprocessor controlled pressure switch with two alarm outputs for alert and shut-off.
Depending on the pressure loss in the filter head, the inner piston moves towards a spring. The position of the piston is registered by a pressure sensor placed in the upper part of the sensor. The measured values are converted to optical and electrical signals. As soon as power is turned on, four green LEDs, under a transparent cover, start flashing to indicate that the system is active. A temperature sensor measures the temperature of the fluid continuously. Once the oil has reached its operational temperature, the device enters operation mode, and the green LED’s are constant. While the filter capacity decreases during operation, the differential pressure rises slowly.
If the contamination capacity of the filter element has been reduced to approx. 25%, the display changes to yellow. If 100% of the capacity is reached, red and yellow LED’s are displayed and the alarm outputs activate, signalling to the monitoring device.
If the system is running idle there is no flow across the filter, so no pressure loss can be measured. Nevertheless, the LED’s and the alarm outputs are self-locking and stay active unless the power supply is interrupted or the reset button is pressed.
Additionally, the device has a self-checking function. In case of malfunction, the red LEDs start blinking and signal output 2 is activated without switching on the yellow LEDs.
