The BS-03 is an Infrared Sensor Technology based type gas detector with smart transmitter. The sensor is integrated to the transmitter having digital LCD-LED display This detec-tor uses high-performance infrared components and micro-control technology, combined with sophisticated SMD process manufacturing. It has good repeatability, temperature and humidity characteristics, as well as long service life and convenient operation.

The output signal of the detector is 4-20mA standard signal with optional HART.

Besides Infrared Sensor the BS-03 is also available with Plug in SMART Sensors for Point Infrared, VOC's, Toxic's, Oxygen and Catalytic Combustion. These sensors are replaceable type and can be replaced without any special tools.
