Product Description:
YJJ MSH-P/CO2/NC/5/V/P/F Non-dispersive Infrared Carbon Dioxide
Sensor
Features:
Carbon dioxide sensor MSH-P/CO2 Description:
Used for detecting carbon dioxide within the ppm and % volume range
The Dynament infrared sensor uses the NDIR principle to monitor the
presence of the target gas. This sensor contains a long-life
tungsten filament infrared light source,
an optical cavity for the gas diffusion,
a dual-temperature compensated thermoelectric infrared detector, an
integrating semiconductor temperature sensor and electronic
equipment to process the signals from the thermoelectric device.
A dual-gas version is available, designed to detect both
hydrocarbons and carbon dioxide. The 20mm diameter packaging is for
the carbon dioxide sensor, and the dual sensors can be used with
digital communication.
Dynament carbon dioxide sensor MSH-P/CO2 Characteristics:
· Provides 3 power supply variants, 80mA, 15mA and 8mA
Industrial ExdIC certification and mining M1 certification can be
used for all variants
· SIL1 certification can be used for most variants
Measuring carbon dioxide from 0 to 10,000 ppm, with a resolution of
10 ppm
Measuring carbon dioxide from 0 to 100% v01. The resolution is as
low as 0.01%
Compared with earlier versions, the response time is shortened
· Selection of output format: digital output (floating point and
binary), direct pellistor replacement or industry standard 0.4 to 2
volts
Manual calibration options can be executed without digital commands
User-configurable using a USB-powered Premier Configuration Unit
· Output can be scaled by % volume or % full scale
Built-in flash memory allows the sensor firmware to be updated
through the configuration unit
· Enhanced EMC protection
