Product Description: TS21I-CAT Model TrueSafe TS21I-CAT gas detector is used to detect natural gas, LPG, coal gas, alkane, combustible gas, and gasoline, Alcohol, ketone, benzene etc., organic solvent as well as Hydrogen gas. Application area of this detector is in Automotive, Medical, Refineries and Petrochemical Plants, Oil and Gas, LPG station, Chemical and Pharma Industries, Power plants, Gas Boiler, and Spray-Paints etc where gas leakage is possible. It reads the gas concentration in Air and transmits to a detection panel over digital bus as well as it shows LEL level on display. Catalytic type of gas sensor is used in this detector. This sensor provides good reproducibility, good performance against changes in atmospheric temperature and humidity. It has long life-span and easy operation. Detector has provision to set Two alarm levels of warnings (High & Low). Relay output is provided and this output can be connected to the conventional Gas Detection Panel OR SCADA system. For BMS connectivity detector has provided RS485 output. Additionally 4-20mA and Selectable 0-5 V & 0-10V Analog output could be also available. Enclosure used is suitable for Zone 1 & Zone 2 hazardous areas. Application:  OIL & GAS refinery Industries  Automotive and Power plants  Refineries and Petrochemical Plants  Medical Laboratories & Chemical storage room  GAS pipe installation areas  Chemical & Pharma Industry  Steel Industries Salient Features:  Calibration required as per OISD / Safety Standards.  Simulate alarm, fault and warning.  Replaceable Sensor Provision.  View gas reading, configuration and diagnostic.  Wide Operating Temperature Range.  Immune to Catalytic Poisons.  Failsafe Operation.
