Shepherd Fixed Gas Sensor

Fixed Gas Sensors

Shepherd’s Fixed Gas Sensors are designed to monitor for gases directly at the leak source, lower the total cost of operations, and assist in cutting greenhouse gas emissions. The unit detects multiple gases and vapors, including CH4, CO2, H2S, LEL, CO, SO2, and O2. On request, sensor packages for ClO2, HCl, HCN, NO, NO2, O3, and PH may be integrated.

These rugged, all-in-one sensors are easy to deploy, set up, and name to indicate specific locations in the field (compressor, doghouse, separator, shale shaker, tank, VRU, etc.). Each multifunction sensor sends calibration status, battery levels, and gas concentrations to the Shepherd communications hub and receives firmware updates and alarm signals. The sensors are protected with corrosion-resistant housing and are rated Class I Division 1. The unit features an intuitive LCD screen for field crew status updates.

Detection

Electrochemical and microchip-based nondispersive infrared (NDIR) optical gas sensors are incorporated in our fixed gas detectors for single- or multi-gas detection. For some toxic gases with low concentrations, electrochemical detection measures the concentration of a target gas by oxidizing or reducing the target gas at an electrode and measuring the resulting current. For other gases, proprietary Shepherd NDIR technology uses an infrared light emitter and an infrared sensor to accurately detect gas type and concentration with uniquely low power consumption, under 3 mW. Shepherd’s Fixed Gas Sensors are proven to deliver high reliability, accuracy, and fast time to detection for growing gas concentrations.
