Honeywell APT2000 Conductivity Transmitter

The Honeywell APT2000 Conductivity Transmitter is a two-wire Conductivity Transmitter, available for contacting or toroidal conductivity cells.  Continuously measures conductivity, chemical concentration and salinity in industrial processes within the chemical, food and dairy, pulp and paper, refinery, and metals industries.


The Honeywell APT2000 Conductivity transmitter has 4…20mA output as standard, with optional HART bi-directional communications allowing remote monitoring/control of the process.


The APT2000 is highly reliable. Constant monitoring of the conductivity sensor and transmitter electronics allows the APT2000 to immediately detect and display any error. Diagnostics are shown on the LCD screen in form of a pictograph or error code. An LED flashes on the front of the transmitter to alert operators and a 22mA signal is sent to the control room to indicate an error.


Available as wall, pipe or panel mount, the APT2000 has an IP65 water and corrosion resistant enclosure. A large LCD display with easy to read and understand pictograph images mean the Honeywell APT2000 is extremely user friendly. The APT2000 transmitter can also be remote controlled via HART communications from handheld device or the control room, adding additional visibility and control to the process.
