Metal Oxide Sensor Management System - AS330

Product Specification

AS330 metal oxide sensor management system

An additional advance in the case of metal oxide sensor technology is the use of AC rather than DC interrogation of the sensing material.This approach provides complementary atmospheric composition information from the real part and the imaginary part of the sensor impedance and introduces a marked enhancement in terms of sensitivity and selectivity.

AS330 Metal Oxide Sensor Management System Specification
? 4 or 8 MMO sensor channels, configurable for a wide range of MMO sensors.
? digital control of heater temperature using an adaptive algorithm and a number of heater temperature profiles to aid selectivity.
? measurement of real and imaginary sensing element impedance.
? usable with a wide range of sensors, to sense alternative gases.
? a range of interface options including CAN, RS485 and RS232.
? supplied with a suitable mains to 12V power supply plug.
? available with PC monitor software, or information to allow users to write their own interface software.
