Grundfos Direct Sensors

These Grundfos Direct Sensors are 2-in-1 silicon based sensors for measurement of flow or pressure or differential pressure.

The Relative Pressure Sensor (RPS) and Vortex Flow Sensor (VFS) are with integrated temperature measurement intended for boilers in central heating units, whereas the Differential Pressure Sensor (DPS) is intended for heavy duty pump solutions.

Grundfos Direct Sensors type RPS, is a series of combined pressure and temperature sensors (two-in-one) designed for high-volume production. The RPS sensors are fully compatible with wet, aggressive media and are available for pressure ranges of 0-0.6, up to 0-16 bar (relative pressure).

Grundfos Direct Sensors, type VFS, is a series of combined flow- and temperature sensors (two-in-one) based on the principle of vortex shedding behind a bluff body. The VFS sensors are designed for high-volume production and are fully compatible with wet, aggressive media. The VFS sensor utilizes MEMS sensing technology in combination with a novel packaging concept using corrosion-resistant coating on the MEMS sensor element. This makes the VFS sensor very robust and ideal for high-volume OEM applications. VFS sensors are available for flow ranges of 1-12, 1-20, 2-40, 5-100, 10-200 and 20-400 l/min.

The Grundfos differential pressure sensor is a true wet/wet solution, available in the differential pressure ranges of 0.6 a 10 bar.
