Overview
The Zone Pressure Multi-Sensor
(Part #NSB-ZPM-SR-ST-D) is the
most flexible pressure sensor on
the market. Output, range, units,
directionality, and response time
are quickly set in the field with no
tools, no power, and no small
components.
The LCD display helps with
troubleshooting because it displays
the actual differential pressure
over the entire operational range
regardless of which pressure
range is selected for output to the
system controller. Three LEDs on
the face of the unit indicate when
the pressure is “Out of Range
Low”, “In Range”, or “Out of
Range High”.
