Additional information

Designed according to the most demanding requirements, the OLCT 80 detector transmitter is one of the most reliable fixed gas detector on the market. This fixed gas detector is available in remote version and uses intrinsically safe or fireproof sensors according to the target gases. The OLCT 80 has been especially designed to detect O2, the combustible, toxic and refrigerant gases: AsH3, C2H2, C2H4, C2H4O, C2H6, C2H6O, C3H6, C3H6O, C3H8, C3H8O, C4H10, C4H10O, C4H6, C4H8O, C5H12, C6H14, C6H6, C7H8, C8H10, CH20, CH3OH, CH4, Cl2, ClO2, CO, CO/H2 null, CO2, COCl2, F2, H2, H2S, HCl, HCN, HF, N2H4, NH3, NO, NO2, O2, O3, PH3, SiH4, SO2 and the volatile organic compounds (VOC).

 

Developed to meet the most demanding requests from industries, the OLCT 80 detector transmitter is a powerful and cost effective fixed gas detection solution. This high-end gas detector can be used in ATEX zone 1 and features a line-of-sight range up to 3 km.

 

This multi-function triple head fixed gas detector is equipped with a digital display, three alarm relays for high, low and fault alarms and two 4-20 mA inputs. Several other input and output types are also available: analog, TOR, RS485 Modbus.

 

The calibration of the OLCT 80 is non-intrusive and can be performed by only one operator either in automatic mode at the sensor location or in semi-automatic mode with confirmation at the gas detection controller.

 

Moreover, as the high-end gas detection technologies used by the OLCT 80 detector transmitter require low power, the gas detector is very energy efficient. This way, fixed gas detection operation costs are reduced.

 

According to the target gases, this detector transmitter can be equipped with XP IR infrared sensors as well as catalytic, electrochemical or semi-conductor sensors. The OLCT 80 can furthermore be configured in standard, stand alone or digital versions.
