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?
- Determine the temperature units you will utilize:
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.
These products provide valuable complementary solutions for those applications requiring high level analog outputs and where the sensor(s) are exposed to conditions detrimental to internal signal conditioning or the required sensor configuration will not accommodate an internal amplifier.
Together with Stellar Technology sensors and connector and cable assembly, Precision Digital readout instrumentation, these signal conditioners provide our customers with a complete measurement system solution.
At Stellar Technology, out options for signal conditioning are wide ranging. Some of the units we provide include the following:
Strain Gage Handheld with Battery Powered Display – This unit is available in two separate ranges which gives the operator the ability to display and consult two different units of measurement. The annunciator lets the operator know which range has been chosen, and measurements for gross, net, peak, and valley are all simple to choose.
Precise Digital Readout Instrumentation – For this option of signal conditioners, we can supply three variations to our customers. One is a strain gage, load cell and mV meter; another option is our dual-line 6-digit display meter; and lastly, we have a low-cost, 4-digit display meter. You can easily view all the product specs at the link above, and be sure to contact our team if you have any questions.
DIN-Rail Signal Conditioners – We can supply numerous options when it comes to this form of signal conditioner. These DIN-rail mounted signal conditioners can be fixed at a point that is away from the environment that is being sensed, adding to operator convenience. These units have been designed to operate as LVDT signal conditioners, force sensor signal conditioners, and more, all in conjunction with Stellar Technology’s products.
In-Line Signal Conditioners – In circumstances when a transducer is exposed to high temperature, corrosiveness, or high humidity, in-line signal conditioners are the model of choice. We have several options available to our customers, and you can view full specs for each model on the link above.
