700/710 Series flammable and hazardous gas detection

Written by: Tom Austin-Morgan | Published:

Oldham has launched the OLCT 700 and OLCT 710 gas transmitters. The 700/710 Series comprises three models -FP, TP or IR- for the detection of flammable, H2S or CO2 gases.

The OLCT 700 can be used in combination with an increased safety approved junction box from your furniture. The OLCT 710 is ready to use and consists of an OLCT 700 attached to a junction box that contains the terminals and an optional surge protection module.

The OLCT 700/710 Series is designed for harsh and extreme locations. It is claimed to provide reliable operation across a temperature range from -40 to 75°C. The plug-in sensors can be replaced in the field. Operator interface is non-intrusive via a handheld magnet and it includes intuitive embedded software.

SIL 2 certified according to IEC 61508:2010 functional safety standard, OLCT 700/710 instruments are also ATEX 2G certified for use in ATEX zones 1 and 2.

While the Model TP is using a poison-resistant catalytic bead sensor to detect combustible gases, the Model IR includes an infrared sensor to monitor combustible or CO2 gases.

The Model TP is equipped with a proprietary solid state metal oxide semiconductor sensor (MOS) and is suited to H2S detection in severe applications where the detector can be exposed to high concentration/temperature and very low/high humidity applications in wastewater treatment plants and the oil and gas industries

The 700/710 Series is compatible with all Oldham MX controllers and is ModBus compatible with the MX 40 which can connect to up to 32 detectors.
