Rightrax HT Specifications

Online Corrosion Monitoring System

HT350x Sensor

Nominal frequency 

5.0 Mhz

Nominal bandwidth 

100%

Operating mode 

Pulse echo

Typical measuring range  3- 16 mm (0.120 - 0.63”) in mild steel

Measuring range is affected by material properties, coupling and other factors

Contact diameter 

7 - 21 mm (0.820”) depending on contact surface radius

Couplant

Metal foil

Coupling pressure 

Varies depending on test surface dimensions and finish

Mounting 

Adaptable clamping system

Cabling

CMX configuration – 5 m (16.4 ft) length cable to open leads (no connector)

Stand alone configuration  - 5 m (16.4 ft) length coax cable

Delay length 

17.7 mm (0.7”)

Delay material

304 Stainless steel

CMX-HT Sensor Node

Probe system

Single element 5Mhz probe with stainless steel delay line. The probe is clamped onto the pipe and coupled to the 

surface with a gold foil.

System thickness 

resolution

± 0.0025 mm 

(0.0001”)

The resolution of the thickness reading through the complete system is the smallest change that can be reliably 

detected. This is influenced by short-term temperature fluctuations. These variations will result in changes in the 

temperature profile across the pipe wall.

Temperature Range

-20 to +350°C 

(-4° up to 

662°F)

Skin surface temperature of test surface.

Thickness resolution 

single reading

± 0.01 mm 

(0.0004”)

With temperature variations at rates less then 1°C (2°F) per minute over a 5°C (10°F) range, the resolution is 

improved to the value obtained using regression analysis.

Thickness resolution  

with regression

± 0.0025 mm 

(0.0001”)

Reading errors due to short-term fluctuations are removed after taking a series of readings over time and 

performing a regression analysis.
