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 explosion-proof 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.
NSF-approved sensors are made of materials approved for potable water applications according to Standard 61.
Stainless steel is generally regarded as safe by NSF and FDA.
Life expectancy of switch contacts varies with application. Ambient temperature changes do affect switch set points, since the gravity of a liquid can vary with temperature.
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/vapor sealing.
Our sensors must not be field -repaired.
Physical damage sustained by product may render it unserviceable.
