Honeywell’s DirectLine® transmitter modules are the next generation family of analytical transmitters.  Unique architecture in the DirectLine transmitters combines the latest in microelectronics technology with the proven performance of Honeywell’s unique sensing technologies, providing unequaled savings during installation, startup, operation and maintenance.  For ORP measurement the DirectLine transmitter modules can be mounted integrally or remotely with the DL3000 ORP electrode.

The DirectLine architecture consists of an electronics transmitter module and a sensor which may be mounted integral to the transmitter or remotely eliminating the need and added cost of a separate analyzer or transmitter. The transmitter modules are intrinsically safe, in a weatherproof, corrosion-resistant sealed composite enclosure.   

Completing the system is a Honeywell Meredian ORP sensor connected to the sensor side of the transmitter and a 4-20 mA weatherproof output cable on the power/output side. The transmitter and ORP electrode is design for outside use in harsh environments where moisture, dust and chemical attack may be present. The module can be mounted on a 2" pipe, wall or DIN rail.

Signal output of the DirectLine transmitter is a standard 4-20madc output proportional to ORP. This signal may be connected to any host monitor or control device that accept4-20 mA loop powered inputs including:

• Single loop Honeywell or competitive controllers
• Honeywell’s HC900 modular control systems
• PLCs with analog inputs
• DCS systems
• Honeywell’s Trendview data acquisitions systems
