Smart Digital Sensors

SENCOM® technology allows sensors to transmit and receive data when connected to FLXA21 transmitter or to any PC with the SPS24 software installed. Digital or Smart sensors maintain specific measurement and calibration data on an integrated chip along that is an integral part of the sensor. This data can be exchanged between the sensor and either a process transmitter, or a laboratory PC using a data management software, like the SPS24. Using historical measurement, calibration and diagnostic data from the sensor, the SPS24 data management system provides technicians with the tools to predict maintenance and calibration frequency, estimate sensor life and project life expectancy. Calibration data can be downloaded or uploaded to and from the digital smart sensor to the FLEXA analyzer allowing for true plug and go field installation.

Data stored in the sensor includes:

  • Calibration Values (Asymmetry, Slope, Temperature Offset)
  • Sensor Status Signals (e.g. Glass Impedance Detection)
  • Reference Junction Resistance
  • Sensor details (Model, Serial Number, and Production Manufacturing Date)
  • The SENCOM® PC Software, SPS24, offers a unique means to optimize the performance of pH/ORP sensors for enhanced reliability and process safety. The software allows the operator to monitor pH/ORP sensor performance, calibrate and configure various parameters.

     

  • The FU24F is a digital smart pH/ORP sensor made with a chemical resistant PPS 40GF body for harsh pH applications.

  • The SC25F is a digital smart pH sensor in a 12 mm design that includes an integral temperature element and a Liquid earth electrode.

  • All-In-One pH and ORP digital smart sensor that keeps the motto "Simple is best" while combing the sensor with built-in intelligence and direct digital communication. 

SENCOM® is the first generation of Yokogawa digital sensors for pH and ORP measuring systems. Our engineers have combined Yokogawa's application proven process sensor line with the innovative capabilities of digital data communication. The SENCOM® smart sensor design provides improved maintenance management and diagnostics to further enhance the simplicity and reliability Yokogawa has always provided. In addition, digital sensors offer the ability to do all sensor maintenance and calibrations in the laboratory which can reduce operating costs (shorter process downtime) and improve process safety issues.

SENCOM® sensors can be calibrated in the laboratory, or at the process site using the analyzer buffer calibration function instead of stored data from the sensor. When the sensor is connected to the data management software the calibration is downloaded into the history file. The available calibration methods using SMART Sensors and FLEXA analyzer are:

  • pH: Manual/Automatic: Zero/Slope, Zero/Slope/ITP (3 point), Zero/Slope 1,2 (3 point)
  • ORP: Manual 1, 2 (point)
  • Temperature

The FLEXA analyzer can be used with either an analog sensor or the new digital SENCOM®. The FLEXA must have the appropriate sensor module installed matching the sensor type to be used. This allows users to keep lower stock levels of analyzers and simply stock the different sensor modules
