ORP transmitter
DL422 Honeywell Process Solutions

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, start-up, operation, and maintenance. For REDOX / ORP measurement the DirectLine® transmitter modules can be mounted integrally or remotely with the Meredian II 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 unique Honeywell sensor connected to the sensor side of the transmitter and a 4-20 mA weatherproof output cable on the power/output side. The transmitter is designed for outside use in harsh environments where moisture, dust, and chemical attack may be present. For submersion or special mounting applications, a remote mounting option is available which connects the electronics module to the ORP electrode via a cable. The module can be mounted on a 2-inch pipe, wall or DIN rail.
