REGAL SERIES 3000
GAS DETECTOR The new REGAL Chlorine or Sulfur Dioxide Gas Detectors are designed for use wherever chlorine or sulfur dioxide is stored, distributed, or where potential leakage would pose a risk for personnel and property. • Properly installed, calibrated and maintained, the REGAL Gas Detector senses the presence of free chlorine or sulfur dioxide in the environment - at levels below those mandated by OSHA throughout the working life of the sensor. • 3 - digit display and 12 LED bar graph shows the chlorine or sulfur dioxide gas concentration. • Audible and relay ‘warning’ alarm at 1 PPM for chlorine and at 2 PPM for sulfur dioxide and ‘danger’ alarm at 3 PPM for chlorine and at 5 PPM for sulfur dioxide. • Displays and transmits sensor or signal failures via an LED and a designated relay. • Maintenance-free sensor. • Capable of transmitting digital information for computerized data logging. • Bar graph LED representing the highest (10 PPM maximum for CL 2 and 20 PPM maximum for SO2) detected level stays lit until manually reset even as the gas concentration decreases.

• No need to flush, purge or recalibrate the sensor after an exposure to chlorine or sulfur dioxide gas. • An “optional” Regal Serial to Analog Converter is available to provide a 4-20 milliamp DC output equal to gas concentration in PPM (mg/l).
REGAL SERIES 3000 GAS DETECTOR THEORY OF OPERATION A regulated voltage of 24 VDC is provided over a two-wire shielded cable to the sensor unit from the detector’s main power supply. The sensor transmitter board converts the sensor cell output, which is representative of the chlorine gas concentration, to a 4-20 milliamp DC output signal for transmission to the receiver board. The receiver board converts the analog current signal to a continuous pulse train for processing by the microcontroller. When the unit is subjected to the varying concentrations of gas (up to 10 PPM for chlorine and up to 20 PPM for sulfur dioxide), the detector displays the actual concentration on the 3 digit display. The respective LED’s on the bar graph also light. As the concentration of gas increases, the appropriate bar graph LED’s blink and the audible alarm sounds when it passes the WARNING alarm point (1 PPM for chlorine and 2 PPM for sulfur dioxide) and the DANGER alarm point (3PPM for chlorine and 5 PPM for sulfur dioxide) thresholds. The LED representing the highest detected level stays lit even as the concentration decreases. The alarms are acknowledged and reset using the keypad. The bar graph LED’s will continue to blink until the gas concentration subsides to normal levels and the system is reset.
