The Honeywell Series 3000 range of transmitters comprehensively monitors toxic and Oxygen gas hazards in potentially explosive atmospheres. Suitable for mounting indoors and out, they are available in two versions and offer Searchline Excellent versatility. The Series 3000 MkII is contained in a flameproof housing, has an intrinsically safe sensor connection, and is predominantly used in Zone 1 applications. However, with the help of the optional remote mounting kit, the sensor of the Series 3000 MkII can be mounted in a Zone 0 environment.

The Series 3000 MkIII is for use with a separate suitable IS barrier (to be ordered separately), allowing the complete transmitter to be used in Zone 0 applications.

These low-powered gas detectors all feature a loop-powered 4-20mA connection, making them ideal for new and retrofit installations. Users can configure the detector through the easy-to-read LCD and intuitive interface, while fault diagnostic software and a programmable calibration period greatly simplify maintenance procedures.

The intrinsically safe smart sensors are supplied pre-configured and can be ‘hot swapped’ without removing the detector’s power, saving time and money during commissioning and routine servicing. A remote sensor mounting kit allows the sensor to be mounted up to 50′ (15m) from the transmitter, making it ideal for operation in difficult-to-access areas.

Series 3000 MkII and Mk III are supplied with all necessary accessories for easy installation. The detector has four mounting lugs for surface mounting and an optional pipe mounting kit. The electrical installation can be made using a conduit or cable with suitable mechanical protection. Available in painted Aluminium LM25 or Stainless Steel 316 with two ¾” NPT entries or two M20 entries with a suitable blanking plug (certification type dependent) included as standard. A weatherproof cap is also included for use in the harshest outdoor conditions.
