VECTOR- COMBUSTIBLE

The Vector represents a cutting-edge point gas detector equipped with a local display feature. It boasts the flexibility to monitor up to two sensors, either directly connected or remotely installed at distances of up to 500 ft. When it comes to combustible detection, the Vector offers versatility by accommodating plug-in sensors, including options for Infrared (IR) or catalytic bead types.

In terms of communication, the unit is equipped with multiple output options, allowing users to connect via 4-20mA, RS485, or relay for reliable integration into their systems. Calibration is made convenient through on-site, non-intrusive processes facilitated by the local display or HART handheld devices. The on-board memory maintains an event log, ensuring calibration records and diagnostics are securely stored.

The Vector serves as a versatile display unit, capable of receiving signals from all ESP Safety gas detectors, including SGOES, TGAES, and PGU. The OLED display provides a vivid representation of gas type, real-time concentration, and alarm levels. Housed in durable stainless steel, the detector combines advanced functionality with robust construction.

Key Features
  • The product is capable of being configured to accommodate 2 detectors, allowing for cost savings by monitoring 2 different gases in a single location or utilizing one display for 2 separate locations. 
  • The event data log is stored in the on-board memory and can be accessed via the display or RS-485 Modbus RTU. 
  • The OLED screen is able to simultaneously display a wide range of data, including gas concentrations, alarm levels, faults, and operational modes.

SGOES

The SGOES Gas Detector is designed to accurately measure the concentration of hydrocarbon gases in a monitored environment. Using infrared light (IR), its sensor detects and quantifies hydrocarbons, expressing concentrations as a percentage of the lower explosive limit (LEL) in the air. Two programmable alarm levels provide timely alerts.

Equipped with a continuous self-check function, the detector notifies users of any obstruction in its field of view or circuit integrity issues. Multiple output options (4-20mA, RS485, or system relay) ensure reliable communication. To address condensation concerns, an internal heater prevents damage, while the device’s low power consumption (less than 4.5W) ensures cost-effective operation.

The SGOES facilitates a seamless on-site non-intrusive calibration process through a magnetic wand or a HART handheld device, requiring calibration only every two years, highlighting its reliability. Unlike some sensors, it doesn’t rely on the presence of oxygen and is not sensitive to gases like nitrogen, oxygen, carbonic acid, ammonia, or hydrogen sulfide, making it ideal for environments with non-hydrocarbon gases. Available in both stainless steel and aluminum housing, the SGOES Gas Detector is a robust and versatile choice for monitoring hydrocarbons in diverse settings.

Key Features
  • Fast Response –High sensitivity to all hydrocarbon gases/vapors within 1-2 sec
  • Wide Operating Temperature –Makes SGOES great choice for challenging applications from -60°C to +90°C
  • 2 year Calibration Interval –The longest industry interval between calibration is 2 years
  • 5 year warranty –Long product life with low cost to operate over time
