L Series Pressure Transducers and Pressure Transmitters

L Series Pressure Sensors - LS, LD, LF

Sensing solutions designed with next generation technology for versatility and ruggedness – power and accuracy.
EVO PRODUCT PLATFORM PRESSURE TRANSDUCERS AND TRANSMITTERS

The L Series (LS, LD and LF) pressure transducers and transmitters are designed using the latest sensing technologies and aerospace-proven processes and quality systems, bringing high performance and reliability levels in easily configured standard option selections. These durable and environmentally robust pressure sensors are competitively priced and compact, with many versions available in a standard one-inch diameter package – making them the best choice for use in many test & measurement, oil & gas and industrial automation applications.

The LS, LD and LF Series pressure transducers and pressure transmitters are part of our EVO product platform – next generation sensor solutions. Quick availability brings our pressure sensors to you within 4-6 weeks, without the wait often associated with custom sensor configurations.

Reliable Performance in Easily Configurable Pressure Sensors

Achieve spot-on accuracy with our easily configurable LS, LD and LF Series pressure transducers and transmitters.


  • The LS Series is a single port pressure sensor product that represents the broadest range of fluid and gas pressure application ranging from test and measurement to aerospace use.
  • The LD Series is a differential (two port) pressure sensing product that is used for measuring pressure loading, flow, liquid level and liquid density.
  • The LF Series product incorporates a sensing diaphragm that is flush to the male port interface resulting in minimal “dead” volume being added to the measurement making it ideal for metering and dispensing applications.

Fundamental to the next generation EVO product line of pressure sensors, you can now specify a configuration that best fits the needs of your application without sacrificing accuracy or reliability. Get the pressure sensor you need, fast, with a quick turnaround time direct from the factory. The most durable and environmentally robust pressure sensors on the market are also the most compact, with all configurations available in four or six weeks, with stocking options available.

Distinguishing Features of LS, LD and LF Pressure Transducers and Transmitters


The LS Series pressure sensors bring features that meet or exceed traditional single port pressure sensor offerings.
 

LS Series

Delivery in 4 weeks or less

The LS Series pressure sensors bring features that meet or exceed traditional single port pressure sensor offerings. Configurable options include a wide range of output signal, operating pressure, sensing accuracy and compensated output temperature calibration options. A broad range of electrical terminations and pressure port configurations have been adapted to our core welded steel, shock and vibration resistant design.

The LD Series pressure transducers and transmitters are compact, reliable and rugged differential pressure sensors with high differential pressure capability.
 

LD Series

Delivery in 6 weeks or less

The LD Series sensors are compact, rugged differential pressure sensors with high pressure capability. These sensors offer long-term stability and feature low sensitivity to shock and vibration. Eliminating the need for two separate single port transducers, they can be calibrated for both unidirectional or bidirectional applications. The smaller size and all welded construction make these units ideal for applications exhibiting higher levels of shock and vibration.

LF Series pressure transducers are extremely small, accurate, reliable flush diaphragm pressure sensors for measuring dynamic and static pressures.
 

LF Series

Delivery in 4 weeks or less

The LF Series pressure transducers are extremely small, accurate, reliable flush diaphragm pressure sensors for measuring dynamic and static pressures. The design is made entirely of stainless steel with a one-piece sensing element offering rugged performance. The product sensing diaphragm is flush to the male port interface, resulting in zero additional “dead” volume – ideal for measurement in metering and dispensing applications.

Industrial Pressure Sensors Designed for Harsh Environments

Pressure sensors are used throughout test & measurement, oil & gas, and industrial automation industries to name a few. Use of pressure sensors is key to driving accurate and efficient processes with more accurate data and control measurements. We apply aerospace-proven processes and quality systems so that each part performs consistently and reliably in harsh environmental conditions. Our combination of knowledgeable personnel, engineering design expertise and manufacturing capabilities enable us to ensure you have the right product for your application, leading to better results at an optimum value.

Applications varying from materials testing equipment to rocket engine performance test rigs, require reliable, continuous high-performance sensor feedback. Pressure sensors are used in these situations to measure variables, such as hydraulic, fuel and atmospheric pressures.
Whether it is hydraulic fracturing, well stimulation or hydraulic pump monitoring, the flexibility to choose the best configuration for a pressure sensor ensures more reliable results. In these demanding applications pressure transducers can be used to control hydraulic pressure, monitor for field equipment failures, as well as provide level or depth monitoring.
Challenging factory automation applications need pressure sensors that are highly accurate and reliable. Our pressure sensors allow customers to continually improve quality and productivity through accurate data and control measurements. Industrial uses include sensing system pressure, monitoring pressure variations in a line, as well as accurately measuring fluid height.
