Oldham OLC 100 & OLCT 100 Fixed Gas Detectors
The Oldham OLC 100 and OLCT 100 are robust fixed gas detectors designed for the continuous monitoring of combustible gases, toxic gases, refrigerant gases, and oxygen (O₂) in demanding industrial environments. Built for reliability and flexibility, these detectors are available with multiple sensor technologies and can be configured to meet a wide range of gas detection requirements.
The OLC 100 features a Wheatstone bridge output, while the OLCT 100 incorporates a 4-20 mA analogue transmitter output, enabling straightforward integration with gas detection controllers, PLCs, and safety systems.
For applications where catalytic sensors may be affected by contaminants or poisons, an infrared (IR) version is available to provide reliable combustible gas detection in harsh operating conditions.
