Important Points:
· Omega products must be maintained and installed in strict accordance with the
National Electrical Code and the applicable Omega Product Instruction Bulletin that
covers installation, operation and proper maintenance. Failure to observe this information may result in serious injury or damages.
· For hazardous area applications involving such things as, but not limited to, ignitable mixtures, combustible dust and flammable materials, use an appropriate explosionproof enclosure or intrinsically safe interface device.
· Please adhere to the pressure and temperature limitations shown throughout this
catalog for our level and flow sensors. These limitations must not be exceeded.
These pressures and temperatures take into consideration possible system surge
pressures, temperatures and their frequencies.
· Selection of materials for compatibility with the media is critical to the life and
operation of Omega products. Take care in the proper selection of materials of
construction, testing is required.
· Our sensors have been designed to resist shock and vibration. However, shock
and vibration should be minimized.
· Filter liquid media containing particulate and/or debris to ensure the proper operation of our products.
· Electrical entries and mounting points in an enclosed tank may require liquid/
vaporsealing.
· Our sensors must not be field-repaired.
· Physical damage sustained by product may render it unserviceable.
