Unpacking
Carefully remove the contents of the shipping carton and check each item
on the packing slip before destroying the packing materials. Any damage
must be reported to the shipping company. If you do not receive all of the
parts, contact Ametek at 800-635-0289 (US and Canada) or 248-435-0700
(International).
Most probes are shipped in a Tube. To remove the metal end cap, use a large,
flat blade screw driver or a metal rod and tap on the inner edge of the cap until
it pivots. Grab the cap and pull it out. Use caution as the edge of the metal
cap may be sharp.
If you have an RMA warranty claim, pack the
probe in a shipping tube or with stiff reinforcement
to prevent the probe from being bent in transit.

Chapter 1: 958A Overview
We know today’s industrial challenges are extreme, so we designed and built a sensor to meet and exceed
these demands, regardless of the application or environment. Innovation, proprietary technology and decades of
experience were the key to the development of our 958A Embedded Linear Displacement Transducer.
The 958A was designed with the mobile hydraulics market in mind. The 958A is a rugged, accurate, programmable
zero & span, auto-tuning, non-contact linear displacement transducer in a compact embedded rod-style package.
The embedded package style allows the unit to be totally installed inside of a hydraulic cylinder, thus protecting the
transducers from outside conditions. The transducer utilizes our field-proven Magnetostrictive technology to give
absolute analog position, accurate to 0.04% of the programmable sensing distance. A variety of different analog
outputs are available to meet your needs.
The 958 has a variety of truly unique features. The first one is the wide power range of 8 to 30 VDC @ 1.6 watts.
The LDT also has auto-tuning capability, the ability to sense a magnet other than the standard ring magnet and
adjust its signal strength accordingly. Our units offer a variety of different analog outputs, all with optional field
programmable Zero & Span points. Units can be ordered in English or metric span lengths from 2" to 100" (50mm
to 2540mm), and come standard with either integral cable assemblies, bare leads or M12 style connectors.
The 958A units offers a unique diagnostic capability. When the magnet is present and within the programmed
range the unit will output a voltage or current within its selected range (depending on location of magnet). If the
magnet moves beyond the programmed ranges the output will indicate this with a voltage or current outside of the
selected range.

Chapter 2: Installing the LDT
The 958A is designed for insertion into mobile hydraulic and clevis style cylinders. The hydraulic cylinder must be
prepped for an Embedded Style Linear Transducer.
Installation Notes: The 958A is offered in either a 10.29mm (.405") or an 8mm (.315) diameter guide tube. There
are 4 different magnet styles offered. When the magnet is installed in a ferrous material it is necessary to add a
non-ferrous spacer between the magnet and piston. Non-ferrous materials, such as brass, copper, aluminum,
non-magnetic stainless steel, or plastics, can be in direct contact with the magnet assembly and rod end without
producing any adverse results. See Figure 2-2.

Chapter 3: Connections and Wiring
Once the LDT has been installed, wiring connections can be made. Units are available with Integral cable
assemblies, bare leads or 5 pin M12 (A-Code) connector options. Refer to part numbering on unit in question for
proper wiring. See Appendix A for part numbering grid. See Figure 3-2 for connection options.
Once the LDT has been installed, wiring connections can be made. On units with the M12 connector option it is
recommended to uses an industry standard 5 pin 12mm Euro style cordset with a shield tied to the coupling nut.
On units with our Integral Cable option the shield is tied directly to the LDT’s housing. To reduce electrical noise
the shield must be properly used. Connect the cable’s shield to the controller system Ground. Always observe
proper grounding techniques and isolate high voltage (i.e. 120/240VAC) from low voltage (i.e. 24 VDC cables).
Warning: Do not use molded cordsets with LEDs!
It is preferable that the cable between the LDT and the interface device be one continuous run. If you are using a
junction box, it is recommended that the splice junction box be free of AC and/or DC transient-producing lines. The
shield should be carried through the splice and terminated at the interface device end.
NOTE: When grounding the LDT, a single earth ground should be connected to the Power Supply Common (circuit
ground). The LDT Power Supply Common should be connected to the Power Supply Common (-) terminal. The LDT
power supply (+VDC) should be connected to the power supply positive terminal (+). The LDT cable shield should
be tied to earth ground at the power supply. The LDT analog common should not be connected to earth ground
and should be used for connection to interface devices only.
The 958A offers up to 16-Bits of resolution, and is fully programmable over the entire active stroke length. Keep in
mind that there is a 1.18” Null Zone at the connector end of the LDT and a 2.49” Dead Band at the other end of the
LDT that the magnet must stay out of at all times. The units come fully programmed from the factory and do not
require re-programming unless desired.
The analog output is referenced to the analog common terminal and should not be referenced to any of the other
common terminals. For wiring, see Figure 3-1. For programming Zero and Span, See Section 3.4.
3.1: Wiring
Figure 3-1 shows two common methods for wiring the 958A to a customer supplied interface device, such as a PLC
or motion controller. The two different methods are commonly referred to as Single Ended Input and Differential
Input. Differential Input is the preferred wiring method.
With the Differential Input, the Analog Common wire is connected to the customer supplied input device and
the Power Supply Common is wired separately to the customers supplied power source. When wired using the
Differential method, the electrical noise and voltage offset errors produced by the currents running through the
Power Supply Common are eliminated. The Power Supply Common and Analog Common are internally connected
inside of the 958A LDT.

3.3: Features
Automatic Gain Control
The Automatic Gain Control feature will automatically search and find the magnet on power up and adjust the
signal strength to the optimum setting. If power is applied without a magnet on the LDT, the LDT will go into a fault
condition and transmit a voltage or current outside of the programmed range. See Chapter 1: 958A Overview, for
list of fault conditions and outputs. To correct this, turn power off and place magnet within the active stroke area,
re-apply power.
3.4: Setting Zero & Span Positions
As an option the 958A can be ordered with Programmable Zero & Span positions. See page 10 part numbering to
see if this option filed was selected. Note: If option “P” was not selected in part number configuration, the unit is
non-programmable.
All units come fully programmed from the factory and do not require re-programming unless desired. The units
are 100% absolute and will not lose programmed parameters on power loss. The Zero and Span points can be
programmed in any order and anywhere within the LDT’s active sensor area.
NOTE 1: Zero or Span can be adjusted individually without setting the other.
NOTE 2: Zero = 0V on 0-10 VDC, 0V on 0-5 VDC, .25 on .25-4.75 VDC, .5 on .5-4.5 VDC units and 4mA on 4-20mA
units.
There is a timing sequence that is used to unlock the probe for programming. This is to insure that the Zero or Span
positions cannot be accidentally re-programmed by someone in the field.
Manual Setting of Zero & Span
To set the Zero and Span position, follow these steps:
1. Apply power to the LDT.
2. Place magnet assembly where Zero is to be located, but within the active region of the probe.
3. Short the Program Input pin to the Power Supply Common for 4 seconds. Remove the short for 1 second.
Within 5 seconds, short the Programming Input pin to the Power Supply Common. This completes the Zero
programming process.
4. Place magnet assembly where Span is to be located, but within the active region of the probe.
5. Short the Program Input pin to the Power Supply Common for 4 seconds. Remove the short for 1 second.
Within 5 seconds, short the Programming Input pin to the Power Supply +VDC.
This completes the programming process.
NOTE: The LDT must be unlocked to program the Zero and unlocked again to program the Span. Once either the
Zero or Span is programmed the LDT will go back into the locked mode.
!
WARNING: During normal operation, electrically insulate the Program wire to prevent accidental setting of
Span.
