1. Introduction The Model BX-597A multi-parameter weather sensor is an “All-in-One” device that measures ambient temperature, relative humidity, and barometric pressure. Sensor performance complies with guidelines establish by the World Meteorological Organization (WMO) and the US Environmental Protection Agency (EPA). The sensor is supplied with mounting hardware and an integrated radiation shield and can be easily attached to lattice tower legs and instruments masts up to 2 inches (IPS) in diameter.

2. Cautionary Statements The sensor’s relative humidity output is referenced to saturated water vapor pressure

above liquid water. When the air temperature is below freezing, the sensor’s maximum theoretical measurement range is limited.

To minimize exposure to direct sunlight, install the sensor facing to the north in the northern hemisphere and south in the southern hemisphere. This orientation will help shield the sensor from direct sunlight and reduce temperature measurement errors.

3. Initial Inspection Upon receipt of the Model BX-597A, inspect the packaging and contents for damage. If

the packaging has arrived in a damaged condition file a claim with the shipping company and contact Met One Instruments, Inc. to arrange for repair or replacement.

The model number and cable length are printed on a label at the connection end of the cable. Check this information against the shipping documents to ensure the correct product and cable length has been received.

4. Product Overview The BX-597A ships from Met One Instruments pre-wired for digital output signals including RS-232, RS-485 and SDI-12. The BX-597A also includes voltage outputs for AT/RH/BP, and an ID voltage used by some Met One monitors and dataloggers to identify the sensor. The voltage outputs are 0-2.5VDC default and can be changed to 0-1VDC or 0-5VDC. The BX-597A uses a piezoresistive pressure sensor, a microprocessor-controlled relative humidity module, and a platinum RTD temperature sensing element. The response of each element is linear with negligible hysteresis. Each sensor element in the BX-597A is controlled using an on-board microcontroller, which contains an analog-to-digital converter and non-volatile memory for storage of factory-determined calibration coefficients. The microcontroller polls the sensor module once per second. Measurements are temperature corrected, the calibration coefficients applied, and the processed measurement sent out via serial communication. All wiring terminals on the BX-597A are protected from static-surge damage by transzorbs and current-limiting resistors.

5. Installation

5.1. Mounting

The BX-597A is designed for outdoor use and is supplied with an integrated solar radiation shield and U-bolts. Install the radiation shield with the U-bolts on any vertical or horizontal pipe up to 2 inches (IPS) in diameter. To minimize exposure to direct sunlight, install the sensor facing north in the northern hemisphere and south in the southern hemisphere.

5.2. Siting

Install the sensor over an open, level area at least 9 m (EPA) in diameter. The surface should be covered with short grass or a natural earth surface where grass does not grow. Locate sensors away from objects at a distance equal to four times the height of the objects, and at least 30 m (EPA) from large paved areas. Protect sensors from thermal radiation and ensure adequate ventilation. Standard installation heights:

1.5 m (AASC)

1.25 to 2.0 m (WMO)

2.0 m (EPA)

5.3. Wiring

The BX-597A may be ordered with a 10547 analog output cable assembly, or 10548 digital output cable assembly (sold separately) for connection (Individual wire leads) of the BX-597A to a data logger, signal conditioner, or programmable logic controller. A detailed wiring diagram for each cable assembly is provided in Section 10: Wiring Diagrams.

BX-597A sensor cables for specific Met One monitors (e.g. BAM-1020 N, BAM 1022, BC-1054, etc.) are included in accessory kits sold with the monitors. Replacement sensor cables may also be ordered separately.

7. Sensor Verification

To verify correct wiring and test the basic sensor operation, blow on the sensor. The warmth and moisture in your breath should cause the temperature and relative humidity reading to rise. The output signals can also be checked against calibrated relative humidity, temperature, and pressure devices. Please note that relative humidity can be expected to vary significantly over short distances and in brief periods of time.

8. Serial Communications Serial Data Output The output of the BX-597A is a fixed length, comma delimited, serial data stream. The serial output is factory set for 9600 baud, no parity, 8 data bits, with 1 stop bit (N, 8, 1). Please see appendix E for a list of supported serial commands. Output Format Detail

The BX-597A will support only one output format. This format will use fixed length fields but also include commas to accommodate both standard CSV formatting and legacy programs that expect fixed length fields.

The parameter order is shown in the table below.

Field Parameter

01 Ambient Temperature

02 Relative Humidity

03 Barometric Pressure

04 Config. & Status

05 Check Sum

The BX-597A will report data at a rate set using the “OI” user command (see Section 12 for command details) and is typically set to one second. An example output string is shown below. +023.6,022.1,0974.3,U0,*nnnn

Page 10: DK > y r ñ õ ó d u µ l Z o ] À , µ u ] ] Ç l } u ] W µ ^ v }...d Z y r ñ õ ó Z ] ( } u D K v / v µ u v r Á ] ( } ] P ] o } µ µ ] P v o ] v o µ ] v P Z^ r î ï î U

BX-597A-9800 Manual Rev B.doc Page | 6

Note: when displaying the pressure in in/Hg, there will be an extra leading zero character but the fixed length of the field will not change.

A check sum parameter will be added to the end of the message (*nnnn). The check sum is the addition of all the characters from the start of the message through the first character preceding the asterisk (*). The check sum is expressed as a decimal number. This is a 16-bit sum and should not overflow past 4 digits, given the number of characters in the output string. Polled Data Mode (RS232 or RS485) The sensor can be set for polled data mode instead of continuous serial output, by setting the serial trigger string while in terminal mode (see Section 12 for command details). SDI-12 Interface In addition to the above communications methods, the sensor can be polled for data by an SDI-12 Master Station. This operates completely independent of the RS232 or RS485 communications and can be used in conjunction with those methods. Data are polled using a series of SDI-12 commands. Please see appendix E for a list of supported SDI commands. The default SDI Address for the BX-597A is zero. Please consult your data-logger manual for more information on SDI interfaces or call Met One for additional help.
