  • Page 5: Overview

    60,000 hours. Unlike mechanical gauges, which collect the precipitation to measure it, the Model 6030 Optical Rain Gauge has no collectors or buckets to corrode or clog. The sensors use automatic gain control circuitry to eliminate the effects of LED output power or dirty optics.

  • Page 6: System Description

    2.1 MAJOR COMPONENTS 2.1.1 Sensor Head The 6030 sensor head uses a compact optical system to measure precipitation. The sensor head frame is an all-aluminum, welded design. The small box (TX) is the transmitter unit and contains an infrared LED and lens with a disk heater. The large box (RX) contains a receiver assembly consisting of a photo diode, a lens with an aperture slit, a disk heater, electronics, an external thermistor probe, and a connector for the signal/power cable.

  • Page 7: Electronics Enclosure

    Model 6030 Optical Rain Gauge User’s Manual 2.1.2 Electronics Enclosure The electronics enclosure contains the processing electronics, power supplies, and surge protection circuits. The electronics enclosure is a fiberglass NEMA-4X type box with a hinged access door. One power supply, and AC and RS-485 interface modules with surge protection are mounted to the base plate of the enclosure.

  • Page 9 Model 6030 Optical Rain Gauge User’s Manual  An Automatic Gain Controlled (AGC) normalizer  A signal processor  A temperature probe  A microprocessor and communications subsystem The transmitter portion of the sensor head uses an infrared LED as a light source that is modu- lated to eliminate interference in the system caused by background light.

  • Page 10: Installation

    User’s Manual 4. INSTALLATION 4.1 SITING AND INSTALLATION GUIDELINES The Model 6030 Optical Rain Gauge may be installed almost anywhere outdoors. An area free and clear of obstructions and contamination sources will help insure good sensor performance. In general, the sensor should be located on level or slightly sloping ground where the sensor site will be exposed to the same environment as the area around it.
  • Page 11 Model 6030 Optical Rain Gauge User’s Manual 5. The sensor head is generally oriented with the transmitter head on the north side (in the Northern hemisphere) so that the receiver optics face north. Align the sensor head so that the receive lens faces north. If the orientation can be altered to either side of north to obtain a “view”...

     Distance between sensor and closest obstruction at least 2 times obstruction height  As far from road, runway, and contamination sources as possible The 6030 Optical Rain Gauge is packed in two heavy-walled corrugated cartons. One carton contains the electronics enclosure and the larger, narrow carton contains the sensor head and cables.

  • Page 13: Mount The Sensor Head

    Model 6030 Optical Rain Gauge User’s Manual 4.2.2 Mount the Sensor Head The sensor must be securely installed and correctly oriented to work properly. Figure 2. Mounting Sensor Head 1. Attach the sensor head using the two U-bolts to connect the mounting plate on the sensor head and the mounting bracket with the ¼-20 hex locking nuts as shown in Figure 2.
