Introduction

As an integrated part of the Advance Optima series the LS25

can be combined with further analyzer modules and completely operated remotely in Ethernet networks.

The LS25 has ATEX, IECEx and CSA certificates for use in potentially explosive atmospheres.

The power supply unit converts 100-240 volts AC to 24 volts DC (24 volts DC can be supplied directly to the transmitter unit if available).

The power supply box is connected to the transmitter box by a cable. 4-20 mA input signal from external gas temperature/pressure sensor

can be connected to the screw terminals in the power supply box or directly to the cable connector on the transmitter unit.

The receiver electronics are connected to the transmitter electronics via a cable.

The absorbed signals detected from the photodetector are amplified and transmitted via this cable to the transmitter unit.

The same cable transmits the required power supply from the transmitter unit to the receiver unit.

The transmitter Al box contains the main electronic components.
