805QS Pressure
Switch-Transmitter
General Instructions
These instructions provide information for installation, process connection,
electrical connection, operation and maintenance of the 805QS pressure
switch-transmitter. The 805QS consists of a field proven sputtered thin film
stainless steel pressure transducer and a reliable switching output. The
housing features a stainless steel construction.
The 805QS is capable of powering long cable lengths. See Formula on page 3
for maximum loop resistance.
NOTE: If you suspect that an instrument is defective, contact the factory or the
®
representative in your area for a return authorization number (RMA). This
SOR
product should only be installed by trained and competent personnel.

Installation
Ensure that wiring conforms to all applicable local and national electrical codes and install
unit(s) according to relevant national and local safety codes.
Normally, line mounting provides adequate support for the instrument.
1st Step: Make the Process Connection
The process connection is threaded onto a fitting within an adequately supported
process piping system.
Use two open end wrenches when connecting the pressure port to a process piping
system: one wrench to hold the process fitting, the other at the hex flat to tighten the
electronic pressure switch-transmitter.
Process connection pipe or tubing may be rigid or flexible.
NOTE: Do not use the 1/2” NPT(M) connection on pressures higher than 5000 psi.

2nd Step: Make the Electrical Connection
The electrical connection may be installed on an adequately supported rigid conduit
system. Use suitable locknuts (not provided) when mounting the instrument to an
unthreaded (knockout) hole.
Securely connect the conduit pipe or fitting by holding the flats on the electrical
connection while tightening.
Electrical connection may be rigid or flexible conduit.
Unit in Hazardous Locations - Prior to removal from service, make sure that the
work area is declassi ed. Failure to do so could result in severe personal injury
or substantial property damage.
Additional Install Steps for Dual Seal Units
Failure to follow these additional installation instructions may diminish the “Ingress
Protection” and “NEMA” ratings of the “Dual Seal” instruments. An improper installation
will void the warranty.
Vertical Installation
The figure on the right depicts the vertical
installation profile; with the electrical
leads on top. The instrument may be
installed with the electrical leads on the
bottom.
The nameplate (tag) should cover the set
screw (annunciation path). Position the
nameplate slot opposite the set screw;
i.e., the nameplate slot should be located
180° from the set screw.

Horizontal Installation
The following figure depicts the proper horizontal installation profile; with the external

The nameplate (tag) should not cover the set screw. Align the nameplate slot with the
set screw; i.e., the set screw should be visible in the nameplate slot.

Switch Operation
The 805QS switch output is a solid state, normally open relay that is rated to 30V,
120mA. This switch can be configured three different ways depending on your
application requirements as noted below. Specific switch action can be requested
at the time of order or can be selected via the optional SOR Calibration Kit at any
time. In all three configurations, the fail-safe state for the 805QS switch output will
be open (i.e., if power is removed from the 805QS, the switch contacts will open
automatically). Please note that the 805QS has a ± 2% URL accuracy tolerance
around each switch setpoint. For best results, SOR recommends the use of some
form of switch latching logic in conjunction with the 805QS.
NOTE: Make certain you are using SOR Calibration Manager software version 3.0.0.6 or greater.
Pressure “Window” Monitoring – This is the default configuration for the 805QS
switch output. In this mode the switch output is closed when the process pressure is
within a user selectable range and open when the pressure is outside of these boundaries. This is designed for applications where there is a known acceptable operating
pressure range. For example, the “window” could be set for an acceptable operating
range of 50PSI to 150PSI. The 805QS switch output will be closed when the pressure
being monitored is between 50 and 150 PSI. If the pressure goes below 50PSI or
above 150PSI, the 805QS switch output will open. (

Window Mode
Single Point: Close on Rise/Open on Fall – In this configuration, the switch output
will be open for pressures less than the selected setpoint. The switch output would
then be closed for pressures greater than the setpoint. (
See
)
Single Point: Open on Rise/Close on Fall – In this configuration, the switch output
will be closed for pressures less than the selected setpoint. The switch output would
then be open for pressures greater than the setpoint. (
See
)
Once the switch is installed and wired into a control or display loop, it is ready for use.
Before applying power, check that the polarity and excitation voltage are correct.

Maintenance
The 805QS contains no user serviceable parts and cannot be repaired on site. It must
be returned to the factory. Disassembly of the instrument by unauthorized persons will
invalidate the warranty. If there is a risk of debris accumulating in the pressure port, it
should be cleaned. Care and caution must be taken when cleaning the pressure port to
prevent damage to the diaphragm.
