The smart pressure switch TS2001 is designed for discontinuous control and pressure indication via
two-state outputs. The switch contains a piezoresistive pressure sensor or, upon request, a ceramic
pressure sensor, depending on compatibility with the measured medium. The measured data are
digitally processed with compensation for temperature dependence and measurement non-linearity.
The entire device is configurable from a computer using a user-friendly application via a USB A/B
cable. It is possible to select the switching function of each solid-state output, the switching level,
and the pressure hysteresis. Pressure switches are especially suitable for measuring level via
hydrostatic pressure; for example, at a level height of 10 m, the resolution is 1 mm.
