Oldham is pleased to introduce its wireless system with the OLCT 80 field detector/transmitter. This new model allows wireless connectivity in ATEX 1 zones.
Features and benefits of the OLCT 80 Wireless include:
An infrared remote controller and on-board display for non-intrusive, one-man calibration;
Flameproof or intrinsic-safety sensors;
A design suitable for explosive areas;
Low power requirements;
Universally accepted frequency of 2.4 GHz/900MHz; and
Flexible input/output options, including analog, TOR and Modbus RS485
Developed in compliance with the strictest specifications, OLCT 80 transmitters are the standard in the gas detection market.
Designed to meet the demanding needs of the largest industrial companies, the OLCT 80 is a major achievement in terms of technical performance and cost optimization. Available as remote version, flameproof or intrinsic safety approved sensors depending on gases to be detected. Detects O2, combustible, toxic and refrigerant gases. Non-intrusive, one-man calibration.
New XP IR infrared sensor for detection of combustible gases or CO2
Stand-alone central unit
For relay control, the OLCT 80 can operate as a standaloneunit: an indisputable advantage in a classified ?explosion risk zone.
Flexibility of connection modes
OLCT 80 sensors can be connected either:
In loop (opto-isolated - up to 16 sensors),
4-20 mA,
Under direct power and operate as a central unit.
Operation traceability
The operator can check records locally for the most recent time-date stamped events.
Communication
Remote dialogue with the sensor using IR remote control.
Measurement power supply redundancy
Independent ports allow a redundant connection to the measurement unit.
Low power requirements
The leading edge technology used in the OLCT80 transmitter makes it very energy efficient.
This major advantage means that more sensors can be connected, with smaller wire cross-sections and overgreater distances.
