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 contacting conductivity measurement the DirectLine® transmitter modules can be mounted integrally or remotely with DL4000 conductivity cells.
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 contacting conductivity cell 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 special mounting applications, a remote mounting option is available which connects the electronics module to the Conductivity cell via a cable. The module can be mounted on a 2" pipe, wall or DIN rail.
Signal output of the DirectLine® transmitter is a standard 4-20mA output proportional to conductivity range determined by the cell and transmitter selection. The transmitter may be connected to any host monitor or control device that accept 4-20 mA loop powered inputs including: :
