这些远场探头包含一个32 dB的前置放大器。这些探头具有更好的防磨效果、更厚的外壳,以及改进的差分响应和信噪比。这些探头用于检测铁磁性管件的点蚀、腐蚀、侵蚀等不规则型缺陷。这些探头备有单激励器、双拾波器和双激励器的不同类型。

远场探头


TRS - 单励磁器

Features

  • Includes a 32 dB preamplifier
  • Improved wear resistance and thicker casing
  • Improved differential response
  • Detects irregularities such as pitting, corrosion, and erosion in ferromagnetic tubingSonde_Tube_CF_TRSOS_03.psd

Probe outside diameter

Probe diameters ranging from 9 mm (0.35 in.) to 26 mm (1.02 in.) are built with a protective stainless steel casing and are available in increments of 1 mm. Larger probe diameters from 22.0 mm (0.866 in.) to 50.0 mm (1.968 in.) are available in increments of 2 mm.

Probes with a diameter greater than 28.0 mm (1.100 in.) have a lightweight design with the probe body made of plastic. This design also includes stainless steel wear rings on each end and a sturdy probe cable to endure multiple probe pulls. Coils are potted (in black on picture) for maximum protection.

Probe center frequency

The most current probe central frequency is 300 (300 Hz) and it ranges from 100 Hz to 1 kHz. Other frequency ranges exist:

  • 02K (2 kHz), ranging from 600 Hz to 6 kHz: not common; can be used for thin and lower permeability carbon steel, such as A-556 or Nickel 200. Probes with this frequency range have a lower gain preamplifier.
  • 15K (15 kHz), ranging from 5 kHz to 50 kHz: used for ferromagnetic stainless steel like SS349 (A-268), duplex stainless steel, or SEA-CURE ®. Probes with this frequency range have a lower gain preamplifier.

Probe cable

Probe cable material is manufactured in nylon (N) only.

Cable lengths are in meters: 20 m (65 ft) is the most common.

Also available in 30 m (100 ft) length.



TRX - 双励磁器

Features

  • Single or dual exciter operation selectable from the software interface
  • Includes a 32 dB preamplifier
  • Improved wear resistance and thicker casing
  • Better detection of irregularities in the vicinity of the support plateSonde_Tube_CF_TRS_03.psd
  • Better sensitivity to pitting when operated in dual exciter mode
  • Improved differential response and signal-to-noise ratio

370 37.0 mm (1.46 in.)
450 45.0 mm (1.77 in.)
550 55.0 mm (2.17 in.)
650 65.0 mm (2.56 in.)

Probe center frequency

The most current probe central frequency is 300 (300 Hz) and it ranges from 100 Hz to 1 kHz. Another frequency range exists:

  • 085 (85 Hz), ranging from 20 Hz to 200 Hz: used for a wall thickness greater than 6 mm (1/4 in.).

Probe cable

Probe cable material is manufactured in nylon (N) only.

Cable lengths are in meters: 20 m (65 ft) is the most common.
