PRODUCT DESCRIPTION

Most building codes  require a very high  ventilation rate  in  enclosed  parking  or  areas  involving  vehicle repairs and operation. This must  be provided during all hours of use. Most codes allow fans to be operated intermittently as long as  carbon monoxide (CO) level does not exceed 25  or 50ppm (check local code). A CO sensor can reduce fan energy costs by switching off or reducing ventilation when CO level is low.

The  CO-T1  is  a  CO  sensor/transmitter   designed specifically for these applications. It  delivers all the advantages of electrochemical  sensing in a durable, long life (5-year) package and at attractive low price. The loop powered  sensor delivers a linear 4~20mA output  that  is   easily  integrated  into  any  building control, ventilation or alarm system.

FEATURES

 Using carbon monoxide electrochemical cell, the CO-T1 offers fast and reliable measurements over a long period of time;

 Measurement range: 0 - 100 ppm CO

 Two-wire 4-20mA linear output signal corresponding to the measurement range

 Long sensor life, up to 5 years

 non-frill design; cost-optimized and loop powered for direct connection to DDCs

 Easy sensor head replacement minimizes long term operating costs

 Optional measurement range (0 ~ 200ppm or 0 ~

400ppm)

 Optional terminals for temperature sensing elements such as PT100, PT1000 or NTC 10K.

  Optional duct mount (-IP65) housing
