Maintenance:

Sensor may require a periodic cleaning of prism surface. A mild detergent may be used to clean prism surface.

This product complies with EN61326 Electrical Equipment for Measurement, Control and Laboratory use - EMC Requirements for Minimum Requirements and Industrial Locations. Special caution should be taken to meet EN61000-4-5 Surge Immunity if any of the following conditions apply to the installation: The product is installed outside; the cable is greater than 30 meters in length. In order to meet the Surge Immunity requirements, the following conditions must be followed during installation:

1. Shielded cable must be used, and the shield must be tied to earth ground (not

3. For the sensor with metal body or enclosure the body/enclosure must be grounded to earth. If a protective metal housing is used, the metal housing should be grounded to earth.

4. If a protective plastic housing is used, the housing must be able to withstand at least 2 kV from the housing to earth ground.

power supply ground) on at least one end of the cable shield/drain wire. The shield must be maintained all the way from sensor to the power supply.

2. If unshielded cable is used, an earth grounded metal conduit can be used to replace the shielded cable.

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.
