Pressure Transducers and Pressure Transmitters
A broad range of pressure sensors designed to reliably deliver more accurate data and control measurements. Standard and configurable options, including output signal, pressure range, sensing accuracy, pressure ports, electrical terminations and compensated output temperature calibration range.
Differential pressure transducers are used for measuring pressure loading, flow, liquid level and liquid density. These transducers offer long-term stability and feature low sensitivity to shock and vibration. Eliminating the need for two separate single port transducers, these sensors can be calibrated for both unidirectional or bidirectional applications.
Flush diaphragm pressure sensors provide accurate, reliable measurements of dynamic and static pressures with a minimum sensing dead volume. Special coatings are available for highly abrasive and corrosive environments. Miniature and sub-miniature sensors are available for confined environments.
Our small, lightweight space-rated pressure sensors combine rugged all-welded stainless steel construction with radiation-hardened electronic components to ensure reliable performance. Additional features include low sensitivity to extreme shock and vibration and wide compensated temperature range.
Sensing solutions designed to address extremely high-pressure applications to 100,000 psi are also ideal for fatigue rated applications up to 50,000 psi. Additional features include all-welded stainless steel design and low sensitivity to shock and vibration.
Sensing solutions designed and certified for years of safe service in the most demanding environments. Hazardous certifications include explosion-proof, flameproof and intrinsically safe approvals (CSA, ATEX, IECEx) for hazardous environment operation anywhere in the world.
Designed for long-term reliable performance in harsh subsea environments, these sensors feature rugged and reliable sensing elements to provide high level signals. Additional features include wide temperature range, low sensitivity to shock and vibration and infinite resolution.
Sensors for use in oil and gas applications are manufactured with special processes to minimize thermal effects and enhance shock and vibration immunity. Most are custom designed and manufactured using specialty materials suited to operations in harsh environments. Additional features include intrinsically safe and explosion-proof configurations designed to meet ABS and DNV certifications.
These transducers combine both a pressure sensor and temperature sensor in one small, lightweight package. This design reduces your sensing costs and required space envelope by effectively eliminating the second sensor package. They can be configured with either analog and digital and industrial network output options.

Selecting the Right Pressure Transducer
Finding the right pressure transducer for your application requires understanding the specific needs and the requirements for the environment in which the sensor will be used. While standard options will normally work well, some applications require custom sensor solutions. These 5 considerations are designed to be at top-of-mind as you search for the right pressure sensor for your application.
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
- 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
- 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
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?
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
