CR800 Measurement and Control Datalogger Description：

Product ManualDatasheet

The CR800 is a smaller, research-grade data logger designed for stand-alone operation in harsh, remote environments. It is intended for smaller configurations in which fewer sensors will be measured. Each CR800 reads input from sensors, then transmits the data via a communication peripheral; most sensors and telecommunication devices are compatible. Multiple CR800s can be configured as a network or units can be deployed individually.

Another data logger, the CR850, is similar to the CR800, but it has an integrated keyboard and display screen for on-site control.

Detailed Description

The CR800 consists of measurement electronics encased in a plastic shell and an integrated wiring panel. This data logger uses an external keyboard/display and power supply. Low power consumption allows the CR800 to operate for extended periods on a battery recharged with a solar panel—eliminating the need for AC power. The CR800 suspends execution when primary power drops below 9.6 V, reducing the possibility of inaccurate measurements.

The on-board operating system includes measurement, processing, and output instructions for programming the data logger. The programming language, CRBasic, uses a BASIC-like syntax. Measurement instructions specific to bridge configurations, voltage outputs, thermocouples, and pulse/frequency signals are included. Processing instructions support algebraic, statistical, and transcendental functions for on-site processing. Output instructions process data over time and control external devices.

Benefits and Features

Ideal applications include wind profiling, weather stations, ETo/agriculture, air quality, soil moisture, water level/stage, aquaculture, vehicle testing, Time Domain Reflectometry, SCADA, and water quality
