MetPak 1 Doc No 1575-PS-0001 Issue 02 CN 4240 March 2006 FOREWORD Thank you for purchasing the MetPak manufactured by Gill Instruments Ltd. To achieve optimum performance we recommend that you read the whole of this manual before proceeding with use. Do NOT remove black “rubber” transducer caps. Gill products are in continuous development and therefore specifications may be subject to change and design improvements without prior notice.
MetPak Doc No 1575-PS-0001 Issue 02 3 PRINCIPLE OF OPERATION 3.1 Wind Speed and Direction Sensor CN 4240 March 2006 The MetPak uses the WindSonic wind speed and direction sensor. WindSonic measures the times taken for an ultrasonic pulse of sound to travel from the North transducer to the South transducer, and compares it with the time for a pulse to travel from S to N transducer. Likewise times are compared between West and East, and E and W transducer.

CS215 Temperature and Relative Humidity Probe The CS215 Temperature and Relative Humidity probe is designed as a reasonably priced probe for general meteorological and other datalogging applications. It utilises the SDI-12 communications protocol to communicate with any SDI-12 recorder simplifying installation and programming. 1. Introduction The CS215 probe utilises a novel single chip element that incorporates both a temperature and RH sensor.
CS215 Temperature and Relative Humidity Probe Response Time with Filter: <15s (63% response time in air moving at 1 m/s at humidities <85% ) Environmental Performance: See Appendix A Calibration Traceability: See Appendix B Supply Voltage: 6-16V DC Current Consumption: Typically 120µA quiescent, 1.7mA during measurement (takes 0.
User Guide For other applications the CS215 can be installed in any orientation. Install it away from obvious sources of heat, including solar radiation. NOTE: It is best to protect the filter at the top of the sensor from direct exposure to liquid water as whilst the hydrophobic nature of the filter will repel light rain, driving rain can force itself into the pore structure of the filter and then take some time to dry out. 4.
CS215 Temperature and Relative Humidity Probe • If long cabling or interference appear to be causing spurious readings then use the `checksummed’ versions of the SD1-12 instructions (see section 5). 4.2 Power Conservation The CS215 draws about 120µA of current between measurements from its 12V supply. When used with the aR! command the average consumption increases by ~50µA over the quiescent as the sensor automatically takes a measurement every 10 seconds.
User Guide NOTE: The sensor will automatically switch to making measurements every 11 seconds (+/-2 second) the first time it receives the aR! command. It makes the measurements based on its own clock which is not synchronised to the datalogger clock. This means measurements made with the aR! command can be up to 11 seconds old. This is not normally an issue for environmental measurements due to slow rate of change of RH and temperature.

User Guide 5.1.2 Example CRBasic Program Measuring One Sensor Every 30 Seconds The following example is written for the CR200 datalogger. Programs for the CR1000 and CR5000 would be similar although many instructions have extra parameters required to control the extra capability in those dataloggers. The SDI12recorder instruction also varies somewhat between the dataloggers – see the CRBasic help for the respective logger for further details.
CS215 Temperature and Relative Humidity Probe The aR! Command would therefore be preferable in fast running programs as it takes less time to execute. The aC! concurrent measurement command can also be used where the sensor measurement is initiated with one command and data is collected after a minimum delay of one second or any time thereafter. With Campbell Scientific dataloggers this is done by using the SDI-12 recorder instruction with the aC! command.
User Guide CallTable CS215dat 'Call the table instruction to calculate and store the Avs NextScan EndProg 6. Changing the SDI-12 Address Using LoggerNet and a Datalogger Up to ten CS215s or other SDI-12 sensors can be connected to a single datalogger control port. Each SDI-12 device must have a unique SDI-12 address between 0 and 9. (The CS215 also supports the extended range up to 126.) The factory-set SDI-12 address for the CS215 is 0.
CS215 Temperature and Relative Humidity Probe 7. To change the SDI-12 address, enter the command aAb!; where a is the current address from the above step and b is the new address. The CS215 will change its address and the datalogger will exit the SDI-12 Transparent Mode. 8. To activate the SDI-12 Transparent Mode on Control Port p, enter pX and press the key. Verify the new SDI-12 address by entering the ?! command. The CS215 will respond with the new address. 9.
User Guide 5. To activate the SDI-12 transparent mode on Control Port p, enter ∗8. The TD datalogger will respond with a “∗” prompt. At the “∗” prompt enter #. The TD datalogger will respond with 150000. Finally, enter p (Control Port p) and press the key. The TD datalogger will respond with entering SDI-12. 6. To query the CS215 for its current SDI-12 address, enter the command ?!. The CS215 will respond with the current SDI-12 address. 7.
CS215 Temperature and Relative Humidity Probe 6.3 CR200 Series Datalogger 1. Connect a single CS215 to the datalogger using Control Port C1/SDI12 as described in Section 4, and download a datalogger program that does not contain the SDI12Recorder () instruction. 2. In the LoggerNet Toolbar, navigate to and activate the Test|Terminal Emulator … menu. The “Terminal Emulator” window will open. In the Select Device menu, located in the lower left hand side of the window, select the station. 3.
User Guide 6.4 CR1000 Datalogger The CR1000 datalogger supports changing the address in a similar way to the CR200. In terminal mode issue the SDI12 command, then give the control port number in response to the prompt. The normal SDI12 command can then be entered (there is no need to enter the “SDI12” prefix as with the CR200). If changing the address you will initially get a “fail” message (as with the CR200). To terminate the SDI12 terminal mode press with no command. 7.

CS215 Temperature and Relative Humidity Probe When used outside the range of normal conditions or when subject to prolonged periods of condensation or freezing the sensor calibration may be temporarily altered, normally resulting in a change of <+3% RH. Once the sensor returns to normal conditions the calibration will settle back, over the course of several days, to the “standard” calibration.
