Description

Sierra Monitor SMC 4101-03 Electrochemical O2 Oxygen Gas Sensor 4-20mA w/ 5358-01

Electrochemical oxygen gas sensor transmitter with 4-20mA analog output. Measures oxygen concentration in fixed gas detection and industrial monitoring applications.

Specifications & What's Included

  • Model: SMC 4101-03
  • Output Signal: 4-20mA
  • Full Scale Range: 25% Oxygen
  • Power Requirements: 20VDC, 1A
  • Includes: Sierra Monitor 5358-01 Calibration Fitting
  • Manufactured: United States (Milpitas, CA)

Applications

This sensor type is used in fixed gas detection systems and industrial oxygen monitoring installations. Electrochemical sensors measure ambient or process oxygen levels in confined spaces, storage environments, and manufacturing facilities. The 4-20mA output integrates with standard industrial control systems and data acquisition equipment. These sensors are common in HVAC monitoring, laboratory safety systems, and process control applications requiring continuous oxygen measurement.

Condition: Used
This Sierra Monitor Corporation 4101-03 Electrochemical Oxygen Gas Sensor has been inspected and appears to be in good used condition. The blue housing and sensor probe are intact with no obvious physical damage. Because the unit has been uninstalled and in storage for some time, recalibration is recommended before returning it to service — the label shows a last calibration date of 1-21-97. The 5358-01 calibration fitting is included. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
