Digital Pressure Sensor Model PSD

Description

The economical PSD offers the ideal combination of two pressure
switches and a scalable transmitter output with a 45 degree
viewable, rotatable display. The parameters can be set directly
on the device. Within the settings, there are a comprehensive
set of options, making the PSD suitable for a wide range of
demanding applications. There is integral hysteresis, window,
and delay functionality included. OEM quantity pricing available
upon request.
