Jireh ROTIX – 4 Probe Weld Scanner w/ PPS

Four probe cantilever scanning with a PPS (probe positioning system) and y-axis encoding (with optional encoder).

The Rotix – 4 Probe Weld Scanner with PPS (probe positioning system) is a manual chain scanner designed to provide encoded probe position of two phased array and two TOFD probes circumferentially around tubes and pipes. The integrated probe positioning system allows the operator to adjust the probe offsets without removing the scanner.

Adjustable Chain

With various link lengths and an adjustable buckle, pipe diameters of 3.8 cm – 96.5 cm (1.5 in 38 in) can be scanned. Quick release links allow for simple and easy scanning of various diameter scan surfaces.

Probe Positioning System

The Probe Positioning System (PPS) provides quick adjustment of the probe center spacing as well as allow an operator to center the four probes over the weld without requiring scanner removal.


The umbilical is modular and can be removed from the scanner. It can be used for one axis and two axis scans when used with optional accessories.


A brake is provided to lock the scanner in a required position.


All wheels are coated with urethane to reduce the effects of foreign debris obstructing the rolling of the scanner. Urethane also eliminates the sideways sliding of the scanner when used in vertical applications.

Removable Handle

The Rotix includes a removable cover which allows easy access to protected connections while also providing a means of cable management.

Built-in Encoder

An encoder is integrated into the body of the Rotix cart. The encoder output is fully compatible with all standard instruments.

Probe Holders

An integrated latch allows easy probe center spacing adjustment and scanner installation. Due to its modular design most major types of phased array wedges can be accommodated.


Covered by a limited 3-year warranty.

Component Identification


1 Stabilizer Wheel

A magnetized stabilizer wheel maintains frame bar balance during scan operations.

2 Slip Joint Probe Holders

Maintain constant contact between the inspection surface and the probe with low profile, spring-loaded probe holders. Extreamly adjustable, these probe holders accomadate most industry standard phased array and TOFD probes and wedges.

3 PPS Encoder

The optional PPS Encoder provides encoded y-axis travel information.

4 Cart

The ROTIX cart is paired with urethane wheels for smooth, unobstructed motion upon scan surfaces.

5 Short Link

Various amounts of single wheel short links are included in each kit configuration.

6 Short Link with Dovetail

Utilize the short link with dovetail to mount accessories such as cable management to the chain system.

7 Catch Link

Works in conjunction with the buckle to mount the scanner to the pipe/tube.

8 Buckle

The buckle connects to the catch link to complete the chain system. Adjust the buckle to control the chain’s tension around the pipe/tube exterior.

9 Long Link

Equivalent to (approx.) 3 short links, the long link is used for larger diameter scans.
