The LDI-127 and LDI-128 Series LVIT (Linear Variable Inductive Transducer) position sensors from Omega are contactless devices designed for factory automation and a variety of industrial and commercial applications such as solar cell positioners, wind turbine prop pitch and brakes, chute or gate positions on off-road or agri-vehicles and packing equipment.

With their modular compact design, superior performance, and excellent stroke-to-length ratio, the LDI-127/128 sensors are ideal for both industrial testing, laboratories, and in-plant or mobile equipment OEM applications.

LDI-127/128 sensors are offered in 10 full scale ranges from 25 to 450 mm (1 to 18"). Operating from a variety of DC voltages, these sensors offer a choice of outputs and all include the Field Programmability calibration feature. The products come with radial exiting cable and two swivel rod eye ends for easy installation. The LDI series also includes a smaller body version, the LDI-119, for those applications not requiring a heavy-duty unit.

A 250 ohm or 500 ohm resistor is required if purchasing the 4-20mA version

Analog I/Os:
0 to 10V output with 12 to 30V input, 35 mA max;
4 to 20 mA (3-wire) output with 18 to 30V input,
60 mA max 75°C (167°F max)
Measuring Range: 25 to 450 mm (1 to 18") full scale
Linearity Error: ±0.15% of Full Scale Output (FSO) typical, ±0.25% max
Resolution: 0.025% of FS
Update Rate: 300 Hz nominal
Operating Temperature: -20 to 85°C (-4 to 185°F)
Temperature Coefficient: 0.015% of FS/degree°C
Vibration: 5 to 20 Hz, 0.5" p-p; 20 to 2000 Hz, 4.2 g p-p
Shock: 1000 g, 11 ms
Terminations: IEC IP67 Humidity: 95% RH, non-condensing
Housing Material: Aluminum

How do I reverse the output signal on a LDI-128-300-A020A? Retracted all the way equals 20mA. Extended all the way equals 4mA.

Asked by: Aaron75
Hi, thanks for connecting with Omega. Unfortunately, it is not possible to change the direction of the output signal on the LDI series sensors. The field programming feature can be used to change to range over which the output signal applies, but it will always be an increasing signal for outward movement of the rod. Thank you and please feel free to contact us with any other questions you may have.

I am connecting a 4 wire LDI -119 to an iNet 1000C, What is the wiring diagram for the connections? I need to know what color wire goes to what input on the iNet device.

Asked by: Don G
Thank you for contacting Omega Engineering. The LDI-119 is a three-wire connection and you will need an external power supply to connect it to an INET system. This answer is a bit involved and I would suggest you call and discuss this with an engineer in our Pressure and Strain department.
