H2S data-logger LOGAZ-PRO

radio frequencyRS-485Modbus

Features • - Measuring range : 0-200 or 0-2000ppm • - Wireless setting by radio, no activation needed on the device • - Outputs : 4-20mA and/or Modbus RS485 • - Memory : up to 500 000 measures • - H2S gaz cell changeable on-site • - Logger enclosure rating IP68 This logger integrates the H2S sensor and some outputs so-called process like 4-20mA and Modbus RS485. The measurement is performed by an electrochemical cell, the measuring head is easily interchangeable on-site and embarks its calibration. The sensor has radio communication capabilities up to 100m for configuration and a logger that allows measurement history retrieval also by radio. Gaz cell features You have the choice between two types of gaz cell : H2S 0-200ppm (Maximum overexposure 500ppm) or H2S 0-2000ppm (Maximum overexposure 10 000ppm). They are changeable very easily on-site with the their keyed connector. Power supply - External : 7 … 30Vdc ; 1Watt max so 150mA (7V) to 40mA (30V) Internal : lithium battery 3,6V 17Ah (PN : A0100009) used for the autonomous datalogger mode Process output External power supply necessary (8…30Vdc) - – 4-20 mA current loop (the sensor can not be powered by the loop: 3-wires connection required) – Modbus RS485 Mode ASCII or RTU Speed (Baud) 600, 1200, … ,19200, 38400, 57600 (default 9600 baud) 8 bits data, 1 stop bit, no parity by default Configurable slave address (default address =1) Reading of concentration on the extended Modbus table (@184 cf : K0K00011, available in the configuration of the logger using our software Avelour)
