Model PT295 Series is a 24 VDC powered gas detector to monitor combustible or Hydrocarbons vapors in air. Detection range is 0-100% LEL (lower explosive limit).
The complete sensor consists of a 316 stainless steel sensor head assembly and an interface module enclosed in a flame proof instrument enclosure. A linear 4-20mA analog signal proportional to 0 to 100% of the detection range is generated by the interface module. Also a digital display and a fully programmable alarm relay is also provided on the interface module.
The detectors feature a simple non-intrusive automated calibration without any manual adjustments. Analog signal and alarm relay are inhibited during calibration mode to avoid any false alarms.
