H-335 is a precision, single axis, wide range inclinometer which measures the angle

(position) of radial water control gates. The H-335 is easy to use, works with any data recorder/logger with

a SDI-12 interface and can be interfaced with SCADA systems. The “Serial-Digital Interface” is ideal for

data logging applications with the following requirements:

Multiple sensors on a 3-wire bus

Low system cost

Up to 200 feet of cable between a sensor and the data recorder

The H-335 has the following features:

Easily attaches to I-beam of gate structure

Gravity referenced sensor allows installation anywhere on the gate structure

Scales the gate position into user units of feet, inches, meters, etc.

Built-in intelligence automatically calculates both gate height and arc length

No hysteresis or backlash

0.03 accuracy over full position and temperature range

Sealed water-tight enclosure

No moving parts or bearings
