ABB Measurement and Analyser AO2000-LS25 Laser Analyser Introduction

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.

The central processor board performs all instrument control and gas concentration calculations.

The main board contains all the electronics required for the operation of the instrument,

such as the diode laser current and temperature control as well as the analogue to digital signal conversion.

The display (LCD) continuously shows the gas concentration, laser beam transmission and instrument status.

an RS-232 port is available for direct serial communication with a PC.

An optional Ethernet board provides TCP/IP communication over a local area network (LAN) as an alternative to serial communication.

All cable connectors are Phoenix VARIOSUB type and are waterproof.
