oldham olct80 gas detector
DESCRIPTION
Learn about the Oldham OLCT80 gas detector in this handy datasheet prepared by a1-cbiss.TRANSCRIPT
Oldham OLCT80Fixed Gas Detector Developed in compliance with the strictest specifications, OLCT80 fixed gas detectors provide market leading solutions
The OLCT80 is cost efficient and superior in technology performances
allowing it to be used across a multitude of applications. The OCLT80
provides distinguished performance in offshore, pharmaceutical and
typical oil and gas applications.
Stand Alone Central Unit The flexibility of the connection modes means that the OLCT80 sensors
can be connected either; in loop (opto-isolated - up to 16 sensors), 4-20
mA, or under direct power to operate as a central unit.
Reliability That’s Legislation Compliant The OLCT80 Series is certified to the specifications required by standards
EN 50054, 45544 and 50104 (environmental standards, explosive and toxic
gases and oxygen) and to the specifications of standards EN 50270, EN
60529 (electromagnetic compatibility, ingress protection).
Project Driven, Bespoke Solutions Using our expert engineering knowledge, the a1-cbiss project team
produce the design, specify equipment and integrate the system before
it’s delivered to site by our service and maintenance team
