Introduction

Model A-5 pressure transducers are all-welded stainless steel sensors built for rugged industrial applications that require high accuracy and measurement stability. Pressure ranges span from 0.5 psi to 60000 psi. They utilize complete four-arm 350 ohm strain gage bridges. The Model A-5 is available with a variety of options for extended temperature operation, electrical terminations and high-level outputs including 5 Vdc or 10 Vdc and 4 mA to 20 mA. Most high-level output models have internal shunt calibration circuits as a standard feature to allow easy set-up of the sensor to the data system. An optional internal signature calibration chip provides calibration information for automatic set up with the Model SC four-or-twelve channel digital indicator.

The gage Model A-5 is a strain gage based transducer. This design references the primary pressure sensing diaphragm to the atmosphere, and provides a stable zero regardless of the transducer environment.

The absolute Model A-5 has an all-welded vacuum reference chamber assuring long-term stability

Setup

Configuration options include:

  • Extended operating temperature range
  • Electrical connection
  • Amplified output (5 Vdc or 10 Vdc and 4 mA to 20 mA)
  • Most amplified models have internal shunt calibration circuits as a standard feature to facilitate sensor configuration on the acquisition system.

The Model A-5 is offered in 2 variations:

  • "Gauge" version: the pressure measurement is made with the atmospheric pressure as reference. It allows to have an offset independent of the environment
  • Absolute" version: the measurement is made with a fully welded vacuum cavity as reference, which increases the long term stability.

Applications

  • processes
  • oil and gas
  • packaging
  • pumps and compressors
