|Gas Type||Natural Gas|
|Model Name/Number||olct 20|
Both models are designed for continuous gas monitoring. OLCT 20 monitors toxic gases and OLC 20 flammable. Housed in stainless steel, detectors are resistant to dust, moisture and corrosion, classified IP 66. Suitable for indoor and outdoor use. Oldham have aimed these as a cost effective solution, with a wide range of gases selectable see ordering information.
The OLC 20 Combustible transmitter has a Wheatstone bridge output mV, sensors have been designed to be reliable, quick responding and poison resistant.
Maintenance and commissioning is made simple, the detector is installed to housing using a M25 or 3/4” NPT thread. Sensors can be removed by turning. Sensors can then be replaced by precalibrated new ones, or calibrated outside the zoned area and refitted.
Based on the Oldham OLC 20 sensor unit, the OLC 20D detector is equipped with a 15 m long cable (standard version) and fitting gland for direct connection to a data logger. A high-temperature version allows operation at 200°C.
