OLC (T) 100 Fixed Gas Detector
Brand: OldhamThe OLC/OLCT 100 range of fixed detectors has been designed for detection of explosive gases, toxic gases or oxygen.
At Oldham, our products are always application driven, solution-oriented. Options include:
- OLCT 100 transmitter with 4-20 mA output
- OLC 100 detector with a Wheatstone bridge output for detection of explosive gases
Available in explosion-proof or intrinsically safe versions, the OLC(T) 100 is suitable for detection of all gases in ATEX zones.
The OLCT 100 is available in a stainless steel version, offering increased resistance to corrosive elements (ideal for marine, wastewater treatment plants, food processing activities.. . ).
This stainless steel intrinsically safe version is certified for use in zones 0 (gas) and 20 (dust), whereas all other versions of the OLCT 100 are certified for use in zones 1 (gas) and 21 (dust).
