Fixed Point Gas Detection Features ・ High Visibility Color Graphic HMI ・ Full Script Intuitive User Interface ・ Interface via Small Magnet or Bluetooth® App ・ 4-20 mA DC Output ・ Optional Modbus and Local Alarm Relays ・ OpCheck® Fault and Performance Diagnostics ・ Non-Hazardous Area Installation NEMA 4X Weatherproof Description Model SA-1N4 gas detection sensors are designed to detect and monitor toxic, oxygen and combustible gases in ambient air. Specific gas type is determined by a selected smart sensor module. Sampling is via diffusion. The design utilizes Safeguard Analytics smart sensor modules which include electrochemical sensors, photo ionization detectors, non-dispersed infrared and a multi spectrum combustible gas detection sensor. Each smart sensor module stores gas type, range of sensitivity, and the last zero and span calibration data points. All electronics are contained within a NEMA 4X weatherproof enclosure suitable for installation in non-hazardous area locations. Model SA-1N4 gas monitors feature non-intrusive calibration using a small magnet or an Android™ phone or tablet and the Safeguard OpCheck Bluetooth application. The color graphic display provides simple and intuitive user interface with real time readings and full script service instructions. Device status is readily determined by screen color; green normal no alarm condition, yellow alarm level 1, red alarm level 2 and blue fault condition. OpCheck OpCheck combines continuous supervision of the gas sensor element and associated circuits then adds analysis of performance data during routine calibration to create a high level of safety and reliability in every Safeguard Analytics gas detection sensor. Using the Bluetooth connection and an Android phone or tablet, OpCheck service reports are readily available in single device or site wide formats. The reports can be uploaded via text or email.
