Axess ER & LPR Field Instruments

Axess Data Collection Unit 

The Axess DCU is a high resolution, battery powered, corrosion monitoring instrument capable of reading all types of electrical resistance (ER), linear polarization resistance (LPR) and galvanic probes.

 

The unit is operated with an integrated menu driven screen for ease of use, providing rapid measurements of metal loss for electrical resistance probes, corrosion rate for linear polarization resistance probes, and current or potential for galvanic probes.  The most recent reading is also viewable on the display.  

 

Up to 7,200 data points are preserved in the internal memory which can be downloaded to the Axess HHU via the RS-232 Serial ASCII connection, for transfer to the accompanying corrosion monitoring software (CDAS) for analysis.  The software is used to graph metal loss trends, calculate corrosion rates with data exportable in csv (comma separated value) format for import into excel and other applications.

Axess RS485 High Resolution Transmitter 

The Axess RS485 Transmitter is a high resolution, multi-functional on-line corrosion monitoring instrument. The high-resolution, 20-bit measurement provides a fast response, obtaining corrosion rates in hours instead of days.  The transmitter is multi-function and can read all types of Electrical Resistance (ER), Linear Polarization Resistance (LPR) and Galvanic probes.  The transmitter can be direct mounted at the probe location using a probe adapter or remote mounted nearby.  The AX-DG RS485 transmitter offers simple installation and RS485 Modbus communication, allowing up to 32 units to be connected in series on a single line.  Setup is simple, using switches to select probe type, Modbus address and other settings.  The transmitter has RTU or ASCII switch selectable communication protocols.

 

The transmitter is available in a weather-proof stainless-steel enclosure or flameproof copper-free aluminum enclosures.

Axess 4-20mA Transmitter 

The Axess 4-20mA Transmitter is a high resolution, multi-functional on-line corrosion monitoring instrument. The high-resolution, 16-bit measurement provides a fast response, obtaining corrosion rates in hours instead of days.  The transmitter is multi-function, and can read all types of Electrical Resistance (ER), Linear Polarization Resistance (LPR) and Galvanic probes.  The transmitter can be direct mounted at the probe location using a probe adapter or remote mounted nearby.  The AX-AN 4-20mA transmitter is loop-powered, for simple installation and operation.  A two-wire-connection is all that is required for both instrument power and data transmission.  Setup is also simple, using a set of switches to select the probe type to be measured. 

 

The transmitter is available in a weather-proof stainless-steel enclosure designed for applications which do not permit aluminum enclosures (such as offshore environments).  Alternatively, a weather-proof aluminum enclosure is also available.
