CR800 Measurement Control Data Collector

overview

The CR800 data collector is a small research grade precision data collector designed to work independently in harsh remote environments. Tend to support small applications that only measure a few sensors. Each CR800 reads the sensor readings and transmits the data through communication peripherals; Compatible with most sensors and communication devices. Multiple CR800s can be set up as a data collector network; Alternatively, numerous CR800 units can also be configured one by one.

Another type of data collector, CR850, is similar to CR800, but with an integrated keyboard display that allows for on-site control.

Advantages and Characteristics

Ideal applications include analysis, weather stations, meteorology/agriculture, air quality, soil moisture, water level/water level, aquaculture, vehicle testing, time domain reflectometry, SCADA, and water quality

In terms of design, cr800 and cr850 are simpler to program and wire.

Support serial communication between sensors and devices through I/O ports

Custom SiC chip with expandable pulse counting, control ports, and serial communication capabilities

Compatible channel extension peripheral devices allow you to expand your system

Supports Pakbus, Modbus, SDI-12, and DNP3 protocols

Including CS I/O ports and RS-232 ports for connecting communication devices

Gas exhaust pipe (GDT) protection input

The battery supports a clock to ensure accurate timing when the data logger is disconnected from the battery power supply

Use loggernet, PC 400, or shortcuts to install

Technical description

The CR800 includes a measurement control module and an integrated wiring panel enclosed in a plastic casing. The CR800 uses an external keyboard display and power supply, and its extremely low power consumption allows it to be powered by a combination of small capacity rechargeable batteries and solar panels, eliminating the need for AC power. To reduce the possibility of inaccurate measurements, the CR800 will pause operation when the main power supply is below 9.6 V.

The internal operating system includes the measurement, processing, and output instructions required for programming the data collector. The programming language is CRBasic, using BASIC like syntax. Measurement instructions include: bridge setting, voltage output, thermocouple, pulse/frequency signal. The processing instructions include algebraic operations, statistics, and transcendental functions used for on-site processing. Output instructions to process data according to time periods or control external devices.

Other compatibility information

sensor

The CR800 has multiple channel types and is compatible with almost all available sensors, including thermocouples, SDI-12 sensors, and 4 to 20mA sensors. The customized SiC chip has expanded its pulse counting, control ports, and serial communication functions. The I/O ports of CR800 can be paired for transmission and reception, allowing for serial communication between sensors and devices.

Measure and control peripheral devices

CR800 is compatible with all of our CDMS (requiring an SCCPI), SDMS, multiplexers, vibration line interfaces, terminal input modules, and relays.

communication

CR800 communicates with PCs through direct connection, NL201 Ethernet interface, multi drop modem, telephone modem (land line, digital cellular, and synthetic voice), RF telemetry, and satellite transmitters (ARGOS, Iridium, and Inmarsat).

The data can be viewed on the CR1000KD keyboard monitor, and the CD100 can be installed on keyboards, user provided iOS or Android devices (login link required), CD295 Data View II monitor, or user provided PDA (PConnect or PContce software required).

SC115 is the only compatible external data storage device. CR800 does not have peripheral ports, therefore it is not compatible with CFM 100, NL115, or NL120.

Envelope

CR800 and its power supply can be installed in any of our standard accessories.

Any 12 VDC sources can power the CR800 data logger. The power supplies commonly used with CR800 are BPAlk, PS150, and PS200. BPAlk provides eight non rechargeable alkaline batteries with an H value of 7.5a and a concentration of 20 ° C.

Both PS150 and PS200 consist of a sealed rechargeable 7aH battery and a charging regulator. Their batteries should be connected to a charging source (or wall charger or solar panel). These two power sources have differences in the charging regulator. PS150 has a standard regulator, while PS200 has an intelligent regulator based on a microcontroller. The regulator of PS200 provides two-step constant voltage charging and temperature compensation, optimizing battery charging and improving battery life.

There are also bp12 and bp24 battery packs, which offer nominal ratings of 12 and 24aH, respectively. These batteries should be connected to a regulated charging source (e.g. a ch100 or ch200 connected to an unregulated solar panel or wall charger).

software

Crcraxy, the full programming language of cr800, supports simple or complex programming and many onboard data reduction processes.
