DESCRIZIONE 

I modelli della serie TS292P sono 
trasmettitori 4÷20mA lineari a tre fili 
in grado di rilevare gas combustibili 
ed utilizzano sensori di tipo “Pelli-
stor” tarabili in % LIE per vari gas. 
Gli apparecchi sono costituiti da 
una custodia antideflagrante EEx 
certificata CESI che contiene il cir-
cuito elettronico e i morsetti di col-
legamento; il sensore è inserito nel 
portasensore cilindrico con filtro 
sinterizzato certificato CESI Ex-d-
IIC-T6, posto nella parte inferiore 
della custodia. 
I trasmettitori TS292P vengono 
normalmente collegati alle nostre 
centrali di rivelazione gas. 

FUNZIONAMENTO 

L'elemento sensibile utilizzato è un 
sensore catalitico “

Pellistor

”, prati-

camente insensibile alle variazioni 
di umidità e temperatura. 

DESCRIPTION 

The TS292P series consists of a 
three-wire 4÷20mA linear transmit-
ters able to detect combustible 
gases by employing a “Pellistor” 
sensor calibrated in % LEL to dif-
ferent gases. 
The instruments comprise of an EEx 
CESI certified enclosure in which the 
electronic circuit and the terminals are 
mounted. The enclosure has a down-
ward facing cylindrical section hous-
ing the sensor behind a sintered 
stainless steel flame trap certified 
CESI Ex-d-IIC-T6. 
The TS292P series is designed to 
be connected to TECNOCONTROL 
gas detecting central systems. 

OPERATIONAL DESCRIPTION 

The sensitive element used is a cata-
lytic sensor “

Pellistor

”, practically insen-

sitive to humidity and temperature 
variations. 

DESCRIPTION  

Les TS292P sont des sondes à 
transmetteurs 4÷20mA sur 3 fils per-
mettant de détecter des gaz combus-
tibles.Elles utilisent un capteur “Pellis-
tor” étalonné en % de la LIE. 
Les appareils sont constitués d'un boî-
tier antidéflagrante EEx contenant le 
circuit électronique et les borniers de 
raccordement. Le capteur est monté 
dans une tête protégée par un filtre en 
metal fritté qui est placé dans la partie 
inferieure du boîtier. La certification de 
la tête est CESI Ex-d-IIC-T6. 
Les TS292P sont normalement utilisés 
avec les centrales de détection gaz 
TECNOCONTROL. 

FONCTIONNEMENT 

Le capteur à combustion catalytique 

“Pellistor”

 utilisé pour la détection 

est pratiquement insensible aux va-
riations de température et d'humidi-
té.
