Below, you’ll find some of the most important aspects to take into account when deciding on the right temperature sensors for your equipment and finding the ideal temperature sensor manufacturers.

Performance Considerations for Our Temperature Sensors

To receive optimal performance from your temperature sensors, be sure to:

  • Identify the range of temperatures you will be measuring with the unit
  • Determine the operating media (fluid) that will be measured
  • Determine the temperature accuracy:
    • +/- degrees
    • +/- % of reading
  • Identify the frequency response that is required:
  • Seconds in fluids to give true reading
    • Function of probe parameters
  • Determine the temperature units you will utilize:
    • Fahrenheit
    • Celsius
    • Rankine
    • Reaumure
    • Kelvin
  • Determine your over-temperature conditions:
    • Will you ever exceed the maximum temperature range?
    • To what degree?

Displacement Sensor Models (LVDT) Products

Linear Variable Displacement Transformer (LVDT) sensors from Stellar Technology are used worldwide in the monitoring and gauging of pavement studies, mining equipment, oil & well drilling equipment, resistance weld stroke, valve position, and assembly processes. Take a look at all of our LVDT options below to find the displacement sensor that meets your application needs.

As a leading LVDT manufacturer, Stellar Technology also provides a selection of DIN-rail mount signal conditioners to complement our AC/AC LVDTs.

These products give you valuable complementary solutions for those applications needing high-level analog outputs in circumstances where the LVDT may be exposed to conditions detrimental to internal signal conditioning or the required LVDT configuration will not accommodate internal amplifiers.

The Benefits of Using LVDT Transducers or Sensors

When measuring displacement, it’s important to have accurate readings with your selected displacement sensor. With some LVDT sensors, you can measure movements as small as a few millionths of an inch, but these transducers offer many more benefits beyond accuracy, such as:

  • Long-Lasting Capabilities  – Because of the unique design, there is no physical contact across the sensing element, meaning there is no wear on the linear displacement sensor.
  • Friction-Free Operations – This design also allows for operations free of rubbing, dragging or other sources of friction, making them ideal for materials testing or high-resolution dimensional gauging systems.
  • Unmatched Durability – Between the design and the high-quality materials we use to make each of our LVDT transducers, our sensors are designed to withstand the elements.
  • Quick Response to Changes – As changes occur in the core position, LVDT transducers are able to quickly respond and adjust accordingly.

Performance Considerations for a Linear Displacement Sensor

The first step to finding the right LVDT sensor is to determine what exactly you need it to do. What do you need it to measure? What performance capabilities must it have?

Before looking for an LVDT transducer, you should first:

  • Determine the measuring range/scope that needs to be measured (the displacement from the null point)
  • Determine the relationship between the LVDT and the part being measured
    • Probe locates on part, but not attached
    • Probe is attached, but cannot be removed from LVDT body
    • Probe is attached and can be separated from LVDT body
  • Select armature type needed
    • Spring return (for applications measuring multiple targets)
    • Captive guided (for applications requiring longer measurement ranges – ±0.5” to ±18.5”)
    • Free unguided (for applications in which part moves parallel to LVDT body and requires frequent measurements)
  • Identify engineering units required (inches, centimeters, millimeters, customer-specified)
  • Accuracy of the sensor
    • Linearity
    • Thermal effect (how temperature affects the output)
    • Total accuracy (static + thermal)

Instrumentation and Signal Conditioners Products

Stellar Technology offers a full line of readout meters, in-line amplifiers and signal conditioners to complement our broad variety of pressure, load/force/torque, displacement, and temperature sensors.

Stellar Technology provides a selection of DIN-rail mount signal conditioners and in-line signal conditioners to complement our millivolt-per-volt output load cells, force sensors, reaction torque transducers and AC/AC LVDTs.
