At Stellar Technology, we provide a selection of DIN-rail mount signal conditioners and in-line signal conditioners to complement our millivolt per volt output pressure transducers.

These products provide valuable complementary solutions for applications requiring high-level analog outputs. They are also ideal for situations where the pressure transducer is exposed to conditions detrimental to internal signal conditioning or the required pressure transducer configuration will not accommodate an internal amplifier.


Custom-Designed Sensors

Stellar Technology also specializes in designing custom pressure sensors for specific applications. Our approach includes direct communication with your engineers to confirm each specification required for your application.

Our willingness to create one-of-a-kind sensors and transducers for unique applications sets us apart from the competition, and ensures that we can solve your application challenges.

  • Explosion-proof configurations designed for upstream oil and gas applications to meet BOEM and BSEE regulations

Cutting-Edge Pressure Technology

At Stellar Technology, we are continuously working to develop and use the very latest technology for each of our pressure sensors and transducers. Our hammer union pressure sensors are a perfect example of our continued innovation.

Some of the great features of this technology include:

  • As part of the next generation of pressure sensors, our hammer union pressure transducer combines a number of unique qualities to create a new and improved system
  • The all-welded construction allows for long-lasting durability and the seals, with an O-ring inside, help to keep out moisture
  • We also included a large port that is ideal for a variety of applications, as well as four smaller ports at the top of the mount to allow drainage of liquid no matter how you mount it
  • The hammer union pressure sensor is EMI- and RFI-protected, as well as shock- and vibration-proof

We even field-tested this product for more than a year before releasing it into the market to test its capabilities and ensure its readiness for you. That’s how dedicated we are to our customers.

How to Select a Pressure Transducer

Before you purchase a pressure sensor, there are a number of factors you should consider. These may range from the amount of pressure the sensor needs to measure to the environment in which the sensor will be used.

Once you’ve determined your specific needs and the requirements for your pressure sensor, you can find the right sensors for your company’s needs, or determine that a customized solution would be a better option.

We’ve divided these factors into five main categories for you to keep in mind as you search for the right pressure sensor for your application.

1. Performance Considerations

As you begin your search for the right pressure transducer, one of the most important considerations is whether it will perform at the level you require. You need to find a product that has the capabilities to handle your specific application.

To do this, you will need to determine:

  • The maximum pressure you intend to measure
  • The pressure reference required by your application (including absolute, sealed gage, true gage, vacuum, differential, etc.)
  • The engineering units you require (psi, bar, mbar, Pascal, atmospheres, inches of mercury, feet of water) or if the units need to be customer-specified
  • Accuracy, both static and thermal
  • Pressure conditions the sensor will encounter, including overpressure, burst pressure, dynamic loading, fatigue loading and vacuum range

2. Mechanical Considerations

  • Physical constraints (size, orientation, location)
  • Type of media (hydrogen, abrasive, corrosive, biological, radioactive)
  • Temperature of media
  • Pressure port and process connection
  • Configuration and other requirements, such as small diameter, flush diaphragm, secondary containment or explosion-proof, among others

3. Electrical Considerations

  • Electrical termination
  • Electrical output from the sensor - is it analog, digital, or a combination?
  • External zero and span potentiometers
  • DIN rail mount or in-line signal conditioning for mV/V units

4. Environmental Considerations

The environment in which the pressure sensor operates plays an important role in the choice of the sensor. In order to receive accurate readings, here are a few things you should keep in mind when choosing your sensor:

  • Operating temperature range - if not compensated correctly, it can change the readings drastically
  • Compensated temperature range
  • Electromagnetic and radio frequency interference (EMI/RFI) conditions
  • Is an Ingress Protection (IP) or National Electrical Manufacturing Association (NEMA) rating required?
  • Will the sensor be in a hazardous environment?
  • Is the sensor intrinsically safe or explosion-proof?
  • Will it be used indoors or outdoors? How will it withstand the elements, dust or dirt, extreme temperature or animals and other critters?
  • Is it submersible (for fresh water or salt water)? What are the depth parameters?

5. Special Requirements

Some systems may have specific requirements such as:

  • Collaboration requirements
  • Special approvals/certifications/testing or cleaning
  • Special labeling requirements
  • Frequency response
  • Shock and vibration resistance
  • Serviceability
