TRANSMITTER INSTALLATION

After unpacking, it is recommended to save the shipping carton and packing materials in case the instrument is stored

or re-shipped. Inspect the equipment and carton for damage. If there is evidence of shipping damage, notify the

carrier immediately.

The enclosure should be mounted in an area that is convenient for servicing, calibration or for observation of the LCD readout.

1. Locate the transmitter within the length of transducer cables supplied. If this is not possible, it is recommended that the

cable be exchanged for one that is of proper length. To add cable length to a transducer, the cable must be the same type

as utilized on the transducer. Twinaxial cables can be lengthened with like cable to a maximum overall length of 100 feet

(30 meters). Coaxial cables can be lengthened with RG59 75 Ohm cable and BNC connectors to 990 feet (300 meters).

2. Mount the transmitter in a location:

• Where little vibration exists.

• That is protected from corrosive fluids.

• That is within the transmitters ambient temperature limits –40 …185° F (–40…85° C).

• That is out of direct sunlight. Direct sunlight may increase transmitter temperature to above the maximum limit.

3. Refer to Figure 4 for enclosure and mounting dimension details. Ensure that enough room is available to allow for door

swing, maintenance and conduit entrances. Secure the enclosure to a at surface with two appropriate fasteners.

4. Conduit holes should be used where cables enter the enclosure. Holes not used for cable entry should be sealed with

plugs. An optional cable gland kit is available for inserting transducer and power cables. The manufacturers part number

for this kit is D010-1100-000 and can be ordered directly from the manufacturer.
