1 I N TRODUCTI ON

The probes of t he series LP…01 allow m easurem ent of phot om et ric and r adiom et ric

quant it ies such as illum inance ( lu x) , ir radiance ( W/ m 2) across VI S-NI R, UVA, UVB,

UVC spect ral regions, t he num ber of phot ons per t im e unit and ar ea in t he PAR region

( 400 nm …700 nm ) .

I n probes LP….01 there is no need for external power supply. The out put signal in m V

is given t hrough a r esist or shunt ing t he phot odiode ends. The photocurrent generated

by the phot odiode when hit by light, is convert ed to a pot ent ial difference, which is

read by a volt m et er. Once t he DDP ( Pot ent ial Difference) is known, t he m easured val-

ue can be calculat ed t hrough t he calibrat ion fact or.

The output signal can be am plified or converted into a 4…20 m A or 0…10 Vdc signal

by using a convert er of t he series HD978TR3 ( 4…20 m A) or HD978TR4 (0…10 Vdc) for

DI N rail at t achm ent , or t he wall m ount ing t ypes HD978TR5 ( 4.…20 m A) and
