Product Overview
The PSW-1110 series are cost-effective, digital pressure switches that are easy
to read, easy to program, and perfect for small spaces.
These miniature pressure switches provide PNP output switch control for non-
corrosive gasses. The PSW-1110 features a bright 4-digit, 7-segment display
that makes it easy to see the current pressure. The display can also be
programmed to turn red or green, based on the switch state, and there are two
LED indicator lights to show when outputs are activated. In short, this miniature
pressure switch has several visual indicators that can quickly show the status at
a glance.
The ultra-compact size and multiple pressure port orientations make this unit
easy to install practically anywhere. There are both a horizontally and vertically
oriented pressure ports so that the most convenient orientation and be used, and
the unused port is plugged with the included setscrew. As an added bonus, the
switch also measures the media temperature and can be set to measure in either
Celsius or Fahrenheit. There is a keypad locking function, to secure against
unwanted button presses or changes made by those unfamiliar with the unit.
The PNP outputs are fully programmable, and the user can also select one of
eight pressure units: psi, bar, kg/cm2, KPa, MPa, inHg, cmHg, and Atm. There
are four options for output modes. The main options are hysteresis and window
modes, and each of those have high and low methods of actuation. See the
Operation Modes section below for more details and the product manual for
operation instructions.
The PSW-1110 is also available with the following options: additional pressure
ranges, NPN outputs, alternate pressure port thread types, and with liquid media
compatibility. If you would like to learn more about these options or require
