CHLORINE GAS IS CORROSIVE, PUNGENT SMELLING, YELLOW COLORED GAS. MONITORING OF CHLORINE GAS IS ASPECT TO AVOID METAL CORROSION AND HEALTH RISK FACTOR. CHLORINE IS HEAVY GAS AND MOSTLY ABSORBED BY METALS.

SENSOR-AE-CLD

THE CHLORINE CL2 GAS MEASURING SYSTEM DETERMINES THE CONCENTRATION OF CL2 GAS IN THE AIR AT AMBIENT TEMPERATURE OF -20°C TO +45°C. THE HOUSING IS MADE OF PLA AND SUITABLE FOR WALL MOUNTING.

THE GAS MEASURING SYSTEM IS CALIBRATED WITH THE HELP OF THE RESPECTIVE TEST GAS USING A POTENTIOMETER; THERE IS NO OR NEGLIGIBLE CROSS-SENSITIVITY TO OTHER SUBSTANCES.

BASIC PROCESSING AND OUTPUT OF THE MEASURED VALUES (LINEAR OUTPUT, 4-20ma) ARE INTEGRATED INTO THE MEASURING SYSTEM. EVALUATION AND FURTHER PROCESSING OF THE MEASURED VALUES OCCUR IN A DOWNSTREAM DEVICE ACCORDING TO THE USERS SPECIFICATIONS (FOR e.g. VENTILATION SYSTEM, LIMIT MONITOR, DISPLAY, PROGRAMMABLE LOGIC CONTROLLER). HOUSING IS IN THREE PART THE MEASURING SYSTEM OFFERS RANGES OF 0-100ppm CL2 THE ELECTROCHEMICAL SENSOR IS MOUNTED INSIDE MIDDLE PART PLA HOUSING ON A SENSOR HOLDER IN FRONT OF THE DIFFUSION OPENING. THE CABLE ENTRY IS A SCREWED CABLE GLAND (PG11) AND IS LOCATED ON THE TOP PART. IN ADDITION, A TRANSMITTER CONTAINING A SIGNAL AMPLIFIER AND AN OUTPUT OF 4-20 mA IS ARRANGED IN THE HOUSING THE TRANSMITTER IS BASED ON THE TWO-WIRE SYSTEM AND PROCESSES AND TRANSMITS THE MEASURED SIGNALS. LOWER PART IS CONTAINING ELECTROLYTE. THE GAS MEASURING SYSTEM MUST BE CONNECTED TO ANY DOWNSTREAM EQUIPMENT BY MEANS OF A TWO CORE, SHIELDED CABLE WITH MAXIMUM 100Ω CABLE RESISTANCE, INCLUDING GO AND RETURN LINE. DO NOT LAY THIS LINE NEXT TO A HIGHTENSION POWER CABLE AS THERE IS A DANGER OF RADIATED INTERFERENCE. THE CABLE MUST BE CAPABLE OF WITHSTANDING THE ANTICIPATED MECHANICAL, CHEMICAL AND THERMAL STRESSES.

NOTE- NEED TO CHECK ELECTROLYTE STATUS AND TOP UP ONCE IN MONTH (15 DAYS IN SUMMER).

PRODUCT DATA SHEET

CALIBRATION- THE GAS MEASURING SYSTEM IS CALIBRATED MANUALLY WITH THE HELP OF TWO POTENTIOMETERS (PZ,PS) AND TWO TEST PINS INSIDE THE HOUSING. FOR THIS, SYNTHETIC AIR AND CL2 TEST GAS ARE REQUIRED.

THIS IS LOW MAINTENANCE, ELECTROCHEMICAL TWO WIRE LOOP POWERED SENSOR.
