The REGAL Model 3002 Chlorine Gas Detector is designed for use wherever chlorine or sulfur dioxide is stored, distributed, or where potential leakage would pose a risk for personnel and property.
When properly installed, calibrated and maintained, the REGAL Gas Detector senses the presence of free chlorine in the environment – at levels below those mandated by OSHA - throughout the working life of the sensor.
- 3 – digit display and Dual 12 LED bar graph shows the chlorine gas concentration for each sensor.
- Audible and relay ‘warning’ alarm at 1 PPM for chlorine and ‘danger’ alarm at 3 PPM for chlorine.
- Displays and transmits sensor or signal failures via an LED and a designated relay.
- Maintenance-free sensors.
- Capable of transmitting digital information for computerized data logging.
- Each Bar graph LED representing the highest (10 PPM maximum for CL2) 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 gas.
- Provides Dual 4-20 milliamp DC output equal to gas concentration in PPM (mg/l) – Isolated and un-powered 4-20 mA.
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.
