Product Overview

The T100 is a highly reliable 4-20mA, 2-wire transmitter housed in a rugged, compact metallic enclosure. It incorporates advanced SMT electronics and a plug-in electrochemical sensor based on micro fuel cell technology. This design is intended to be inherently stable and maintenance-free. The sensor uses capillary diffusion barrier technology, which results in a direct response to concentration and a low temperature coefficient, keeping it relatively unaffected by pressure.

Key Features

• 2-wire, 4-20mA Transmitter output.
• Plug-in electrochemical sensor based on micro fuel cell technology.
• Features built-in ZERO & SPAN controls for "one person" calibration.
• Uses SMD electronic circuitry.
• Certified ATEX II 2 G EEx ia IIC T4.
• Enhanced RFI and EMI resistance.
• Works with most 4-20mA controllers.

Gases Detected

The sensor detects gases that react at the electrode surface either by oxidation (e.g., CO, H2S, SO2, NO, H2, HCN, HCI, O2, C2H4O, SiH2, NH3) or by reduction (e.g., NO2, O3, CIO2, and Cl2).

The available full-scale ranges include:

• CO: 50 ppm to 2000 ppm
• H2S: 5 ppm to 1000 ppm
• O2: 5% to 30%
