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.
