102+

In the 102+ amp board, there are 5amplifiers:

PID- high input impedence- namps

CG, TCD, IR- Wheatstone bridge-measure diff. T for CG, TCD or microbolometer for IR

EC1- Biased or UnbiasedEC2- O2 or Unbiased

EC3- Unbiased

Photoionization Process

R + h = R+ + e Where:

R= a molecule with an IP = IP of

the molecule

R+ is the ion formed by the process

that is collected in the ion chamber-concentration is proportional to thecurrent produced

Snap-On Modules

It is possible to have multiple heads forthe 102+ or other models- (electronics forhead are $350 plus sensors)

CG, TCD & IR use the same circuit but aresetup differently (current)-can haveseparate heads for each

Unbiased EC sensors can be interchanged

by customer, recalibrated then run Readout unit will recognize type of PID or

type of WB/sensor

library of 20 compounds. This allowsthe user to calibrate with one gas andvia the library function, correct forresponse and LEL value for any of the> 20 gases in the library


39/51


Types of Sensors-LEL

LEL Two heated catalytic

elements are set in ablock; one is sealed; theother is in contact with thesample. Each is in a leg of

a Wheatstone Bridgecircuit. If the samplecontains hydrocarbons orcombustible inorganiccompounds, they will burnincreasing the temperatureof the sensors andchanging the resistance.The change in resistance isproportional to theconcentration.
