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.

New Diaphragm-Operated Pressure Switches for Tough Environments

Riverdale, NJ, May 31, 2017 – For operation in tough environments, Sigma-Netics, Inc. has added two diaphragm-operated options to its portfolio of ruggedized pressure switches. Similar products were only previously available in piston-based operations.

The new 745 and 785 series of pressure switches are designed for low-pressure, high-sensitivity applications, including off-road or industrial OEM equipment, train braking systems, compactors, compressors and fuel systems. For maximum environmental protection, the 785 model is equipped with a 2- or 3-pin Deutsch connector.

Compliant with IP67 standards, both models have a temperature range of -40 to +250°F and are designed to thrive in tough environments containing oil, fuel, water, dust, vibration or shock. Custom configurations are available.
