Part number: SX1000-MK10
c. Housing Rotation
To improve field wiring access or provide better viewing of the LCD
display, the housing and sensor can be slightly rotated from each
other.
1. Use a 3 mm hex wrench to loosen the set screw to rotate the
housing.
2. Do not rotate the housing by more than 90° max (1/4 turn
only)to the left or right from its original position.
3. Over-rotating can damage the transmitter. A loose housing to
sensor connection may cause water ingress issues.
4. Must tighten the set screw after making the adjustment.

Page 17
DIFFERENTIAL PRESSURE TRANSMITTER - USER GUIDE
d. Straight Threaded Connection
Picture 1: The length of pressure transmitter thread should be longer
than the depth of the thread to ensure an effective seal with the head
gasket.
Picture 2: The length of pressure transmitter thread should be shorter
than the depth of the thread to ensure an effective seal with the root
gasket.
e. Cable Protection Conduit
When using Explosion-proof pressure transmitters in hazardous
locations, a metal Explosion-proof conduit should be used to connect
the cable into the threading box, and lead to a non-hazardous
location.
WARNING: Do not open when an explosive atmosphere is present.
WARNING: A seal shall be installed withing 50 mm of the enclosure.
f. Zero Point Calibration
•Perform the calibration after completing the installation because the
mounting position will affect the zero setting.
•The transmitter must be isolated from the process.
•No pressure or medium on the measuring diaphragm, the system is
under atmospheric conditions.
•Power connection please refer to Local LCD Display Interface sections.
•Please set PV=0 after three weeks of installation to ensure the best
accuracy
•Set PV=0 at least once a year.

3. HARDWARE OVERVIEW
1. Enclosure
All housing entries MUST be tightly SEALED using thread seal tape or
sealant. Failure to seal all port entries may allow moisture to enter the
transmitter housing, cause damage to internal components, and void
warranty.
All housing covers MUST be tightly fastened to protect against external
environmental elements.
Check the housing cover O-ring(s) every time the access cover is removed.
- Apply lubricant if the O-ring is dry.
- Replace the O-ring when it is damaged, discolored, or showing
signs of wear.
- The O-ring should be seated firmly on the bottom of threads
without stretching to fit or without bulging.

4. SAFETY, CERTIFICATIONS, COMPLIANCE
1. Safety
CAUTION: Ensure installation of the transmitter meets applicable state and
National Electrical Code requirements. The installation of the transmitter
should only be performed by a qualified installer or a factory
representative.
WARNING: The pressure transmitter is powered by an external power
supply. The power supply circuit must comply with energy-limiting circuit
by relevant standards and pay attention to the high voltage circuits that
may exist.
WARNING: Do not exceed the maximum static pressure rating of the
sensor.
WARNING: Using the pressure transmitter in hazardous areas, installation,
use and maintenance must also comply with the operation manual and
relevant requirements of national standards.
WARNING: Disassemble the pressure transmitter only at normal
atmospheric pressure.
WARNING: EXPLOSION HAZARD – THIS DEVICE SHALL BE REMOVED
FROM THE AREA KNOWN TO BE HAZARDOUS IF MAINTENANCE IS
REQUIRED.
WARNING: To prevent static discharge, wipe with damp cloth only.
WARNING: Although the transmitter is very durable, do not install it on
high vibration applications or where transmitter is subject to severe
mechanical shock.
WARNING: If the equipment is used in a manner not specified by
OleumTech, the protection provided by the equipment may be impaired.
WARNING: Safety of any system incorporating the transmitter is the
responsibility of the assembler of the system.
WARNING: Do not open when an explosive atmosphere is present.
WARNING: A seal shall be installed withing 50 mm of the enclosure.
