OLCT 700 / 710

Series OLCT 700/710 industrial gas detection sensors are a new generation of intelligent sensor modules that incorporate and integrate several leading edge improvements. The sensors are specifically designed for harsh and extreme locations. This new and superior level of environmental durability in sensor design includes an electropolished 316 stainless steel housing, multi-layered transient spike protection circuitry and 100% encapsulated electronics. The sensor electronics are completely protected and immune to water ingress and corrosion. The gas detector sensor elements are all plug-in components and can easily be replaced in the field.

Operator interface is non-intrusive via a small handheld magnet. Configuration and routine calibration is intuitive and menu driven with fully scripted instructions. Sensor status is displayed on a built-in alphanumeric LED display. Model Series OLCT 700/710 intelligent sensor modules feature dual outputs, a linear 4-20 milliamp analog signal and a Modbus RS-485 serial output. It is becoming increasingly important that safety systems meet the Safety Integrity Level (SIL) requirements of IEC 61508 and IEC 61511. The SIL rating can only be determined by considering the complete safety system.

Series OLCT 700/710 sensor modules are designed with this in mind and feature a new and unmatched level of pre-emptive fault diagnostics. Application variables like input voltage range, operating temperature range, maintenance schedule, detector reliability and output integrity are all monitored and reported via the 4-20 mA and RS-485 serial output. As a component of a SIL rated system, the Safe Failure Fraction (SFF) of SERIES OLCT 700/710 sensors are designed to meet the requirements for any SIL 2 rated system.

Series OLCT 700's sensors utilise distinctive gas detection technologies to satisfy a wide range of industrial applications that require monitoring of, toxic and flammable gases.
