2.0 Installation
The H-3342 is suitable for outdoor environments but must be installed in a protective enclosure
or gauge house. Normally, the H-3342 is screwed or bolted to a shelf in the gauge station with
the pulley and tape protruding over the edge of the shelf above the water. Make certain the
housing is level and the pulley and tape do not rub on any obstructions.
2.1 Making Output Connections to the H-3342
The H-3342 is a SDI-12 V1.2 compliant sensor. It connects directly to any data recorder with
SDI-12 capability. In addition, the H-3342 has an optically isolated, 4-20mA output.
The power for the H-3342 is supplied
by the +12Volt DC input. The table
below shows the proper connections.
The wiring diagram is printed on the
H-3342's housing. A 6-conductor
cable is supplied with the H-3342.
