Thiết bị đo độ bay hơi đầu ra tương tự Campbell Scientific 255-100

Overview

The 255-100, manufactured by Novalynx, determines evaporation rate by measuring the changing water level in an evaporation pan. The evaporation gauge produces a resistance output that our dataloggers can monitor. The 255-200 or another standard National Weather Service Class A evaporation pan must be purchased separately.

Benefits and Features

  • Low-power device for reading the water level of an evaporation pan such as the 255-200

  • Compatible with all Campbell Scientific dataloggers (including the CR200(X) series)

Detailed Description

The 255-100 consists of a float, pulley, and counterweight attached to a precision 1000-ohm potentiometer mounted through a gear assembly in a weatherproof housing. It has a triangular base plate equipped with three leveling screws and a bubble level. The potentiometer produces a resistance output proportional to the position of the float, which can be monitored on site using a datalogger or monitored remotely by telemetry equipment.

The 255-100 can be placed directly in the pan, or connected to the pan using the 255-100P/F stainless-steel pipe and fittings. Instead of using the 255-100P/F, a 1/2-in. polybraid (fiber reinforced) flexible tubing, nylon fittings (1/2-in. NPT x Hose Bar), and small stainless-steel hose clamps can be used; this equipment is available from a local hardware store.
