An Important Update About Sigma-Netics Operations During the COVID-19 Pandemic

As all of us confront the COVID-19 crisis, we wanted to let you know about the status of our operations. Sigma-Netics is an essential manufacturing business as a critical supplier in defense and medical supply chains. Both our New Jersey and Virginia facilities continue to operate—accepting new orders and shipping existing orders for pressure switches, pressure sensors and metal bellows.

The health and safety of our customers and employees is our primary concern, and we have undertaken additional sanitation measures and are practicing social distancing within our facilities. All employees not directly involved in assembly or manufacturing are working from home.

We will continue to monitor global and domestic conditions, and we will provide updates on changing business conditions if they occur.

Satisfying the Unique Pressure Sensing Needs of Submersible Vehicles

Recent growth in unmanned underwater vehicles (UUVs) across several industries is also creating a need for depth transducers that can satisfy unique sensing and instrumentation requirements. Not only must UUVs operate in difficult conditions, their designs are as varied as their missions. That’s why we introduced a depth measurement device for use with submersible vehicles — the SST 74X-UV Series transducer.

Sigma-Netics SST74X UV Transducer

Our SST 74X-UV transducer meets the submersible industry’s demand for precise depth measurement, boasting accuracy of ±0.15 percent full scale output (FSO) total error band (TEB). The sensor is also versatile, featuring a configurable-flange design that allows outboard or inboard bulkhead installation along with digital and analog outputs to allow designers to connect to their choice of instrumentation. Additional features and specifications include:

  • An easily cleanable wetted area.
  • Outer diameter: 0.75 inches (19 millimeters) max.
  • Lightweight: <0.2 pounds (90 grams).
  • Standard ranges: 0-100, 250, 500, -750, 1500, 2000, 3000, 5000, 7000, 10000 psia/psig/psis.
  • Wetted parts made from 15-5 PH stainless steel or Inconel.

Greater Design Freedom

The SST 74X-UV is the latest in our growing line of Sigma-Netics pressure transducers that perform in harsh operating environments. By combining accurate pressure sensing with a configurable-flange design and both analog and digital outputs, the SST 74X-UV transducer gives engineers the freedom they need to implement depth measurement into their UUV designs.

New Pressure Transducer for Submersible Vehicles

Riverdale, NJ, January 31, 2020 – Sigma-Netics, Inc., a global manufacturer of pressure switches, pressure transducers and metal bellows assemblies, has introduced the SST 74X-UV Series depth transducer — a highly accurate depth measurement device for use with submersible vehicles. Designed to address the unique sensing requirements of unmanned underwater vehicles, these compact, shallow-diaphragm sensors feature a configurable flange design that allows outboard or inboard bulkhead installation along with digital and analog outputs.

The saltwater- and freshwater-compatible SST 74X-UV transducer delivers ±0.15 percent full scale output (FSO) total error band (TEB) accuracy, and its heavy-duty construction ensures excellent vibration and shock resistance. Additional features and specifications include:

  • Outer diameter: 0.75 inches (19 millimeters) max.
  • Lightweight: <0.2 pounds (90 grams).
  • Standard ranges: 0-100, 250, 500, -750, 1500, 2000, 3000, 5000, 7000, 10000 psia/psig/psis.
  • Wetted parts made from 15-5 PH stainless steel or Inconel.

The SST 74X-UV is the latest in a growing line of Sigma-Netics pressure transducers that stand up to challenging operating environments. In addition to our standard catalog products, Sigma-Netics offers customized solutions for cases in which standard catalog products will not meet an OEM’s application requirements.
