Table 1. Gas sensor types.
Apart from gas concentration, an appropriately equipped monitor can also meas-
ure temperature, differential pressure and atmospheric pressure and calculate a number of
auxiliary parameters (such as: stack loss, excess air factor, flow velocity and many others).
3.5.2. Additional and optional equipment
The following modules can be chosen as the additional equipment of the maMoS
monitor:
the additional gas channel which separates one or more sensors from the
main gas channel (see chapter 3.2. ),
a module for digital recording of the measurement results – data-logger. It
enables the user to save measurement data on a flash memory card - MMC
(MultiMedia Card) / SD (Secure Digital) ,
replacing the RS232C interface with a RS485 interface which enables the
device to operate in a network (up to 15 devices) and extends the communic-
ation lines up to 100m,
replacing the RS232C interface with a USB interface to make operating with
computers not equipped with a RS232C connector possible,
replacing the RS232C interface with the Ethernet connector,
communication cable of a non-standard length,
