Series 3000 MkII transmitter ATEX 4-20 mA 2-wire loop fixed gas detector with display
The Series 3000 MkII gas transmitter is a fixed gas detector powered by a 4-20 mA 2-wire loop for use in potentially explosive atmospheres (ATEX zones). This Honeywell transmitter is a low power consumption fixed gas detector that can be integrated into any type of new or modern installation.
Equipped with a large LCD screen and magnetic switches, this toxic gas and oxygen fixed detector can be set up non-intrusively using a magnet directly through the glass window of the display. Detailed description
3000 MkII Series Gas Transmitter
Patented Surecell™ electrochemical sensors
The Series 3000 MkII gas transmitter uses Surecell™ electrochemical sensors, ideal for hot and moist environments. Made of stainless steel, the smart sensors are supplied preconfigured, tested and calibrated. These Honeywell transmitters are intrinsically safe and can be replaced while powered without having to shut down the detector, saving time for commissioning and routine maintenance.
Patented Reflex™ self-diagnosis
The Series 3000 MkII fixed gas detector has the patented Reflex™ diagnostic sequence which automatically checks whether the gas sensor is present, in open circuit or in short circuit. If the electrochemical sensor cell fails these tests, the sensor error code is displayed.
The Reflex™ sequence does not apply to nitrogen monoxide and oxygen sensors and regular performance checks and calibrations are still required.
A gas transmitter for regulations compliance
The Series 3000 MkII gas transmitter is compliant with the main certifications in Europe (ATEX), the United States (UL), Canada (c-UL), South America (Inmetro) and international standards (IECEx). It is even ATEX zone 0 certified in Europe!
Many accessories are available (as options) to facilitate the Series 3000 MkII gas transmitter’s implementation, such as the remote sensor mounting kit (up to 15 meters), the pipe fixing kit (for monitoring gases circulating in pipes) or the weather protection device.
