pressure transducers | pressure sensors | OEM

Harsh applications and environments call for equipment that can meet particular demands. For these types of demands required by Original Equipment Manufacturers (OEMs), Ashcroft is excited to announce the release of the S1 pressure transducer.

Designed for large-volume manufacturing, the new Ashcroft S1 is a high-quality pressure transducer at an economical cost that is available with quick lead times. Specially made for applications that include mobile hydraulics, performance racing, agriculture and refrigeration, the S1 is a reliable solution for harsh environments.

This article will dive into the features and specifications of this new pressure transducer so you can see if it’s the right fit for your process.

Important Features

The S1 features a compact and rugged design that offers a variety of housing and connection material options along with high EMI/RFI immunity ratings.

Other features include:

  • All Stainless-steel thin film pressure CVD-based sensor technology for exceptional cycle life and repeatability
  • TruAccuracy™ performance that ensures rated accuracy out of the box so it’s ready for installation with no additional calibration adjustments required
  • High vibration and shock resistance
  • IP65 and/or IP67 levels of ingress protection (depending on the electrical connection used)
  • The ability to operate in temperatures from -40°F to 257°F (-40°C to 125°C).
  • Flexibility for a large offering of different process connections, electrical connections, outputs and pressure ranges


This pressure transducer utilizes an all-Stainless-steel (17-4 PH) sensor element with available options of aluminum, brass, carbon steel or Stainless steel for the process connection and housing.


Reference Temperature:
72 °F ±2 °F (21 °C ±1 °C)

Total Error Band (TEB) Accuracy*:
±1.0% of Span: From 0º C to 85 ºC (32 ºF to 185 ºF)
